This application is a division of application Ser. No. 08/312,650 filed Sep. 27, 1994 now U.S. Pat. No. 5,922,996. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to cables and conductors and, in particular, to insulation therefore. 
     2. Brief Description of the Prior Art 
     In alternating current or direct current electrical power transmission, electrical conduction processes in condensed matter, under certain conditions, consist of the transport of heat, electric charge, mass, and magnetism or some combination of the four in some possible response to an imposed temperature gradient, electric field, density gradient, or magnetic field. 
     Electrical conductivities vary greatly between various materials, and conductivities may vary by an amount of 20 decades or more between metals and most commercially used insulating materials. In electrical cables a thermodynamic equilibrium is established between the particular materials used as the electrical insulation and the electrical conductors. 
     Influences on the conduction processes in insulation are known as traps, polarizability or treeing. Such influences contribute to what is known as electrical breakdown, either thermal or electronic. External cold temperature plays a part in insulation degradation (i.e., cracking) by what is known as cold bend or static temperature. An insulation or dielectric material can under certain conditions experience dielectric breakdown or may spark over when the insulation or dielectric strength drops either because of deterioration, impurities, moisture or physical abuse or damage by the user or abnormal electrical conditions. The existence of foreign materials in the insulation and also what is known as electrically stressed insulation, may under certain conditions result in dielectric break down resulting in heating and unwanted shorts. Some dielectric heating may also result from molecular friction from alternating current which may result in a dielectric loss and dielectric strength drops. Presently today&#39;s commercial insulation on an electrical cable assembly or wire hides electrical damage and does not have the capabilities to indicate and/or locate varied inner cable faults and/or malfunctions and/or damage and/or hazards. 
     Therefore, it is an object of the present invention to provide an electrical cable assembly that will indicate, through an attention getting means, preferable visually through sight or smell or taste or touch, the presence of a fault and/or malfunction and/or damage and/or hazard in the electrical cable assembly. A further object of the present invention relates to a repair jacket and tape to be used in combination with an electrical cable assembly where in the repair jacket or tape also has the capability to indicate the presence of electrical repaired cable faults, and/or malfunction, and/or damage, and/or hazard by an attention getting means. 
     SUMMARY OF THE INVENTION 
     It is an object of this invention to provide a new jacket, sheath or insulation covering for electrical cables or a new electrical cable assembly with at least one attention getting stimulation means, which will be know as a reactee, having a noticeable awareness means, by giving off at least one response by a reacting material that may be at least one visual or color change that is temporary or permanent or in combination and/or testable and/or odoriferous and/or physically changeable that may extend or travel through some dimension of the cable that will: 
     detect an electrical overload condition of itself; 
     detect and/or locate the spot of internal electric sparks and arcs and/or a pre-shortening condition, and/or an intermittent malfunction; 
     detect and/or locate the spot where the beginning of an internal dielectric break down process is starting and/or taking place; 
     detect and/or locate the spot where internal dielectric break down is occurring and/or was occurring; 
     give information as to whether a particular circuit is on or off under the proper environmental and engineered conditions; 
     give an indication of an arc or spark and or dielectric break down and the conduction process occurring internally; 
     detect and/or locate its own internal electrical malfunction quickly without devices or electrical and electronic instruments, making itself capable of indicating its own condition or conditional level without reference to a normal function, and may automatically reset itself with no calibration needed; 
     allow inspectors to see dangerous cable and wires that should be taken out of service; 
     reduce the risk of fires, electrical shock and electrocution and thus make for a safer electrical distribution system; 
     warns of harsh environment temperature, example: cold bend, “WARNING—DO NOT BEND,” so cable insulation does not crack when cable assembly is bent; 
     give a visual warning of the existence of critical temperature ranges or thermal ratings for electrical insulation as is set forth by the National Electric Code or a governing agency or a manufacturer&#39;s specifications: 
     to deter a child or pet from playing with (i.e., especially putting in the mouth); 
     provide any of the above mentioned functions so that a partially color blind persons can see critical points or critical temperatures and detect and/or locate electrical problems; 
     provide any of the above mentioned functions so a totally blind person can tell a critical point or critical temperature and detect and/or locate electrical problems; 
     provide any of the above mentioned functions so that the hearing impaired person can identify a critical point or critical temperature and detect and/or locate electrical problems; 
     provide any of the above mentioned functions if desired a better higher surface electrical resistance of ohmic values by spacing strategically the visually reacting formulation so a surface area of higher resistance surrounds the surface area of a lower resistance visually reacting formulation or by adding at least one additive; 
     provide any of the above mentioned functions with a displayable form of moving colors, or a color moving effect, and/or a readable language or alphanumerics. 
     This new electrical cable assembly, repair jacket and tape, alone or in combination, consist of an electrically insulating means which can be described as containing or coupled to a reacting material. The reacting material, a reactee, reacts while maintaining its insulating properties to various cable conditions. The reacting material can be coupled to an electrically extending electrovisual wire, cord or cable. A reactor is an internal and/or outer abnormal condition occurring within or on an electrical cable assembly and having noticeable results to the outside of the electrical cable assembly through the reacting material, the reactee. The preferred action of the electrically insulating means is an outer visually reacting reactee reacting to an internal reactor. 
     The term “reactive” or “reacting” as used herein will be understood to mean a change which will gain the attention on one via the sense of sight or touch. Examples include color changes or lettering or words which suddenly appear and become visible or physical deformations like swelling, blistering, shrinking and/or melting. Other sensory-like changes will include non-palatability when a material or composition is chewed or bitten into, (i.e., hot pepper extract, citric acid, etc.) or audio resulting from special materials that produce sounds when undergoing physical deformation, and/or smell, from releasing material composition (i.e., methyl nonylketone, oil base odor releasing gels, a sulfur base composition that may contain chlorides, etc.). 
     The term “electrical cable” as used herein will be understood to mean or comprise an electrical wire, cable or cord, electrically insulated wire conductor, an electrical cable assembly or anything used in the form of an extending or rope-like insulating and conducting medium for the transmission, distribution, conduction or retainment of electrical energy. The electrical cable may have at least one delivery system, for example, an insulated conducting path, which is used as a facilitator for the transmission, distribution, conduction or retainment of electrical energy. The electrical cable assemblies disclosed in this patent application may facilitate electrical energy of the alternating current, direct current, analog, or digital type. The electrical cable assemblies discussed in the patent application may also use the inventive features in this patent application separately or in some combination. The term “visually reactive material” or “visually reacting material” as used herein may be, but is not limited to, a liquid crystal material because of (i.e., electrorheological fluid, magnetorheological fluid, thermochromic polymer gels). Preferred liquid crystals derive from the thermotropic group, particularly: cholesteric and/or chiral nematic subgroups. They may have designer formulations so that they function via color change within a predetermined range. The term “visually reactive material” or “visually reacting material” may also include electrical or magnetic field sensitive compounds that can also display a color change due to variations in electrical or magnetic field sensitive compounds that can also display a color change due to variations in electrical or magnetic fields. Additionally, some chemical compounds exist in materials that produce deformations in themselves and the surfaces to which they are coupled when subjected to pressure variations (i.e., pressure variations stemming from variations in heat within an electrical cable assembly). 
     The term “visually reacting material” as used herein may be a thermochromic liquid crystal material which may be selected from but not limited to one or more of the following: Methoxybenzylidenebutylaniline or terephthal-bis-p-butylanaline. Some preferred liquid crystal materials are commercially available from the company “Hallcrest” under trade names BN-g90 C5w, BCN-g100 C, BCN-g-30 C5w, BN-R88 F10w, BN-G98 FLOW or BN-R98 FLOW. “Visually reacting materials” of the type that visually indicate variations in electrical or magnetic fields may be commercially available from the company “E.M. Science Co.” under the trade name of Licrilite. 
     The term “visually reacting material” will also include thermochromic ink and/or die and/or paint compositions and/or a thermochromic polymer and/or a liquid crystal polymer. It is found that some visually reacting materials may be advantageously used in amounts from 0.05 to 5 grams per square foot. Attention getting materials or visual reactance may be in powered form. 
     The term “visually reacting material” will also include any other material that emits light or has a fluorescence property or changes in transparent, or in color in response to, changes in temperature or electrical activity. These materials may also exist in the form of slurries, inks, dyes, paint combinations or can be impressed/impregnated in any flexible or inflexible substance so that the material can be coupled in some manner to an electrical cable assembly, repair jacket and/or tape. 
     Some visually reacting materials may require a specific background or dropback of a certain color in order to properly contract the visually reacting material when it undergoes a color change. This background can be used to enhance, aid or manipulate the visual effect of the visually reacting material. The color of the background can be made from inks, paints, dyes or even the natural color of the cable or its insulation or the color stemming from their ordinary manufacturing processes. 
     Protective coverings, which may range from transparent to opaque, may be utilized to protect some types of visual reacting materials or reactees. The protective coverings may also have an electromagnetic frequency selectivity ability. They may also have some of the proprieties of filtering, absorbing or reflecting lightwaves so as to transform the reactions of the reactor or reactee in order to aid the reacting material&#39;s reactance to it. Protective coverings may also be designed for harsh environments or weatherproofing. This new electrical cable assembly, repair jacket and tape, alone or in combination, may also consist of this protective cover which can be described as containing or coupled to a reacting material, to be known as a reactee reacting to a reactor, while maintaining its protective properties. 
     The term “protective” will be understood to mean protection for visually reactive material from environmental harm. Some examples are the damaging effects of chemicals, solvents, oils, moisture, water, radiation, sun rays, insects and animals or weather conditions. Further, the electrical insulation of an electrical cable assembly, repair jacket or tape may contain insect, animal and/or child-protective or repulsive qualities (i.e., an unpalatable insulation composition, i.e. methyl nonylketone, hot pepper extract, citric acid, etc.). 
     Even a protective cover may have visually reacting results or physical deformations by way of polymer liquid crystals or thermochromic impregnated rubber compound coatings or heat-shrinking polyester coatings that blister, bubble or peel on a cable subjected to a malfunction which causes a variation in the cable&#39;s temperature or electrical/magnetic field. The protective cover may also be heat retaining or heat reflective or heat conducting depending on desired results that my be wanted from such protective coverings. 
     The term “transparent,” as used herein as a property of a protective covering will be understood to mean clear, color-tinted or semitransparent or as understood in the art. The transparent protective covering may have openings used as vents and/or transparent protective coverings may be made of a porous material (i.e., osmotic polymer or a semi-permeable membrane). 
     Another feature of the present invention is that the electric cable assembly may contain a bad tasting composition to prevent the cable from being chewed by rodents or other animals, which may act as a pet or child-proofing. In another extreme it may be designed to attract insects and rodents in order to trap or exterminate them. 
     The term “couple” will be understood to mean containing, or united with, any manufacturing process that makes (i.e., screening, layer, impregnate, film, paint, die, etc.) in order to join together various materials, structures, or layers of an electrical cable assembly, that has means for indicating all functions therein, in particularly the means. 
     The next three terms “damage”, “fault”, and “hazard” are mentioned together here not only because of their differences but because of their relative relationships with one another. The three terms “damage”, “fault”, and “hazard” as used herein will be understood to mean the following as described in the next three paragraphs. 
     The term “damage” as used herein will be understood to mean: any physical injury or harm suffered by an electrical cable assembly. This may include any abnormal material condition occurring, or that has occurred, or that may occur in, and/or on an electrical cable assembly, either to an insulation thereof (i.e., traps, polorizability, treeing, dielectric breakdown, thermo breakdown, etc.) and/or a conductor within the electric cable assembly (i.e., an open conductor, an intermittent conduction by conductor, an irregularity etc.). 
     The term “fault” as used herein will be understood to mean: any electrical conduction process, and/or electrical condition that is abnormal for an electrical cable assembly (i.e., shorts, ground, phase to phase, return to hot, overload, under voltage load resistance short, etc.). 
     The term “hazard” as used herein will be understood to mean: a risk of danger, because of an increment of deterioration to be and/or done, either by damage and/or fault to an electrical cable assembly. Thus a hazardous electrical cable assembly may have at least one damage resulting in at least one fault, and/or at least one fault resulting in at least one damage to an electrical cable assembly. Both damage and fault may, under certain conditions, give variation in temperature, and/or agenetic, and/or electrical fields. When the two results, fault nd damage feed one another, a serious situation develops that can get very dangerous, fires or electrocution and the likes will result especially when fuses or breakers do not work properly for whatever reason. Thus making my electrical insulated cable having means or manifestation abilities for indicating malfunction therein, an excellent warning means, detecting trouble, potential trouble, and/or location of, in and/or on an electrical cable assembly, by this new electrical cable assembly itself. 
     Therefore, I have invented a hazard and/or fault self-indicating electrical cable assembly, repair jacket and tape which may be used in conjunction with one another or alone. The electrical cable assembly may include electrical insulation surrounding electrical wires, wherein the insulation is covered by a layer of or impregnated with a reacting and/or visually reacting material. The layer of reacting material and/or the layer of visually reacting material or impregnated insulation may then be covered by a transparent protective cover and/or may be a protective cover with a means to path the release of responses of reactable materials, and protective cover may be reactive. In another embodiment, the electrical cable assembly and repair jacket may also have visually reacting material embedded in a groove that runs axially to the electrical cable assembly. Furthermore, the reacting and/or visually reacting material may be arranged on the outside of the electrical insulation in spaced repeating sets of locations and/or markings where a set is comprised of multiple locations and/or makings of reacting and/or visually reacting material. Each mark and/or location within a set would be capable of measuring a different magnitude of a hazard an/or fault and/or producing a different response to same magnitude of hazard and/or fault. Alternatively, each spaced repeating sets of markings can be spaced repeating sets of bands that encircle the cable assembly and give the appearance of motion. These locations and/or marks or bands may also be embedded into the transparent protective layer rather than layered atop the insulation. Reacting and/or visually reacting material may also be applied to the outer surface of the insulation in the form of descriptive words or alphanumerics so that these would communicate a hazard and/or fault to a user or observer in a special predetermined manner. 
     An embodiment of the hazard and/or fault self-indicating electrical cable repair jacket comprises a shell formed as a rectangular or tubular sleeve member where the shell is composed of an electrical insulation covered by a reacting and/or visually reacting material. The jacket may have a longitudinal split on one side to facilitate adapting it over and around an electrical cable, possibly for cable repair purposes, or electrical trouble shooting. Reacting and/or visually reacting material may be either layered on the outside or impregnated into the insulation and may be covered by a transparent protective cover like that of the cable assembly. In another embodiment, the electrical cable jacket may be a tubular sleeve-like member where the inner diameter of the jacket is larger than the outer diameter of an electrical cable so that a small gap is formed, possibly for fire-preventative purposes whereby the jacket acts as a flame conduit. 
     An embodiment of the fault-indicating electrical tape comprises a substrate with an adhesive backing on one side and on the opposed side a reacting and/or visually reacting material which may be covered by a transparent protective cover like that of the cable assembly. Alternatively, the electrical tape may include electrical insulation on the opposed side whereby visually reacting material may be embedded into this insulation. This tape will be flexible, and may be stretchable.

     DETAILED DESCRIPTION 
     Referring to FIGS. 1 a  and  1   b , this electrical cable assembly may include any features of FIGS. 1 through 17 including  17 . In FIGS. 1 a  and  1   b , this electrical cable assembly has a conductor  10  surrounded by an insulation  12 . Now taken the steps of progression of which improves and makes a new cable assembly out of the old one, it would be to preferably have a background or colored dropback, exposed by the outer surrounding surface of insulation  12  which preferably would be a dark background, and if not, an artificial dropback may be needed to be added which would then cover at least a portion of this outerly insulation of  12 . Insulation  12  is then surrounded by a layer of visually reacting material  14 . The visually reacting material  14 , may be a thermochromic material, a luminescence material, a liquid crystal material a odor-releasing material, or a taste-releasing material either used separately or in some combination. The thermochromic materials of it may include thermochromic ink, die, paint, etc. The liquid crystals at  14  may include liquid crystals polymers, or thermochromic liquid crystals, or thermochromic polymers. That layer of visually reacting material or reactee having its special purpose is covered by a transparent protective cover  16 . The transparent protective covering  16  may also be made of a cellophane, a clear polymer, a clear polyester, an osmotic polymer, a semipermeable membrane and the transparent protective cover may even have thermochromic properties. The osmotic polymers or semipermeable membrane covers of  16  are means in which to release the responses from reacting material of  14  and  17 . Any break in the conductor would cause the visually reacting material to glow or can become fluorescent or change colors in the vicinity of that break thereby indicating the location of the break and the facilitation of its repair, the reactor being or being started by electrical energy internally. Referring to FIGS. 1 a  and  1   b  also, the number  16  may be a physical deformation material, and the number  14  may be a fragrance or odor releasing material. In this alternate type of assembly both  16  and  14  are reactees having their own special purpose, reacting to an internal and/or external reactor. Referring to FIGS. 1 a  and  1   b  also, the number  16  may be an easy deformable material protective covering, and the number  14  may be a bad or very repulsive tasting material, in this alternate type of assembly only  14  would be a reacted having its own special purpose, reacting to an outer reactor. Referring to FIGS. 1 a  and  1   b  also, the number  16  may be a physical shrinking material and/or number  12  may be physical swelling material while number  14  may be a pressure sensitive material producing a visual change or fluorescence when  16  and/or  12  is activated. 
     Referring to FIGS. 1 a  and  1   b  also, the number  16  may be an opaque deformable material protective covering, and the number  14  may be a luminescence phosphorescence and/or fluorescence material that would be covering number  12  the insulation of an electrical cable assembly. Also, the protective transparent cover  16  is a means to release visual responses of visually reactive material  14 , and the protective transparent cover may be thermo chromic. 
     Also referring to FIG. 1 c  an alternate cable assembly may consist of number  13  being a odoriferous releasing material or  13  may be a taste able material or  13  may be a combination of both odor releasing and bad tasting materials with a protective cover  17  that has openings or vents at  9  in which  9  makes a means to path the release of said material responses. The openings or vents may be on an angle  8 , making a close able flap  7 , so the material of  13  does not get on anything when cable is being handled. The protective cover  17  may have pores represented by number  8  and  9 , the protective cover  17  may also be a transparent protective covering. Also the said materials at numbers  13  and/or  14  may be classified as react able or reacting materials having an attention getting and/or awareness means, which makes an excellent electric cable assembly for handicap people that may be blind or hearing impaired. The material of numbers  13  and/or  14  may be used also as a pet or child proofing electric cable assembly, as well as a handicap cable, because they will be notified by an announcement from this kind of electrical cable assembly that something is wrong, or something is being done wrong. The vapors or gas of an odoriferous (odor and/or fragrance) material number  13  may be activatable by the internal heat from a malfunction occurring within the electrical cable assembly and may travel through pores  8  and/or  9  or alternate porous semipermeable membrane of osmotic polymer covering number  16 , also number  17  may open and lose pores and/or vents  9  and/or  8  by thermo expansion nd contraction the thermo energy coming from internally of cable assembly. 
     Also referring to FIG. 1, it should be mentioned that the visually reacting or an attention getting material of  14  completely surrounds the conductor  10 , so even if conductor  10  or insulation  12  was not circular there would still be a viewing range of at least 360 geometric degrees as in FIG. 15 at number  146  of the reacting materials in FIG. 1 number  14 . 
     Referring to FIG. 2, this electrical cable assembly may include any features of FIGS. 1 through 17 including  17 . In FIG. 2 the electrical cable assembly includes two lengths of electrical conductors  18  and  20  and in both conductor  18  and  20  here is an irregularity  22  and in the insulation  24  there is a impurity  21 , detectable under certain conditions by the cable&#39;s electrical insulation  24  which is impregnated with a visually reacting material, and may have an optional protective transparent covering  26 . In this type of alternate cable assembly the reactee is in the cable&#39;s insulation. 
     Referring to FIG. 3, this electrical cable assembly may include any features of FIGS. 1 through 17 including  17 . In FIG. 3 the electrical cable assembly includes conductors  28 ,  30  and  32  along with insulation  36 . Layers of visually reacting and/or reactive material which react at different temperature ranges or some physical component of electrical energy either directly or indirectly and upon their activation appear in different colors at same critical condition are shown at  38 ,  40  an  42 . The entire cable is covered by an optional transparent protective cover  44 . Another assembly method is to consecutively have embedded in this protective cover  44 —starting at  45 A or either embedded into cable insulation  36  starting at  37 ; or layered in consecutive sections at  39  between an optional protective transparent cover  44 , and an optional outer dropback of outer cable insulation  36 ; layered sections or pockets of the first type of visually reacting or reactive material at  45 A,  45 B and  45 C. The second type of visually reacting or reactive material is housed in or layered at pockets at  46 A,  46 B and  46 C. The third type of visually reacting or reactive material are at the layers or pockets at  47 A,  47 B and  47 C. Some malfunctions in the cable as would cause visual or physical reaction in the visually reacting or reactive material are shown, for example, in the conductor  28  at numeral  29  dielectric breakdown is in the insulation  36 , at numeral  48  shorting is in the insulation  36 , at numeral  50  is in the conductor  32  making a load condition. Also referring to FIG. 3 a luminescence material, fluorescence and/or phosphorescence may coat an electrical cable assembly at  38 , then it may be coated with a clear substrate or covering at number  40 , so as to coat substrate or covering  40  with a thermochromic material at  42  which is dark or opaque at normal electrical and/or insulating conditions and then has transparency to abnormal electrical and/or insulating conditions which is protected with a protective cover  44 . 
     Referring to FIG. 4, principles of which may be used in any FIGS. of  1  through  17  including  17 . In FIG. 4 there is shown a diagram in which various colors are visible at same temperature in the cable shown in FIG.  3 . At the point shown at numeral  52  colors are blue, yellow and red at 50 degrees C. At the point shown at  54  colors are red to yellow to blue at 40 degrees C. to 50 degrees C. At numeral  56  colors are red to yellow to blue at 45 degrees C. to 55 degrees C. At point  58  colors are red to yellow to blue at 50 degrees C. to 60 degrees C. Point  60  coincides with  54 , point  62  coincides with  56  and point  64  coincides with  58 . This chart indicates that if the critical temperature of an electrical cable assembly is, for example, 50 degrees C. then a color can be seen by a partially color blind person at numeral  52 . At 50 degrees C. three colors would be visible at once, they are in one spot, or each color may neighbor each other at same general location of an electrical cable assembly. Each different color at numeral  52  comes from each different reacting range of numeral  54 ,  56 , and  58 . A partially color blind person may only see one, or possible two of these colors, but they would see at least one. 
     Referring to FIGS. 5 through 7, there is shown a jacket that may have any features of FIGS. 1 through 17 including  17 . In FIGS. 5 through 7 the jacket is to be used to retrofit an existing electrical cable assembly with the features of this invention. The cover has a split  66 , pockets or locations of thermal liquid crystal or visual reactive material  68  and  70 , and clear protective heat reflective cover  72 . There is an electric insulating and heat conducting jacket  74 , and the space  76  between this jacket cover  74 , and the clear protective cover  72 , may have a heat absorbing sealing material or be vulcanized together sealing the space  76 . The entire or part of this structure may also have mechanical memory, clipping onto or off of a cable, being reusable. 
     Referring to FIGS. 8 and 9, another electrical cable assembly that may include any features of FIGS. 1 through 17 including  17 . In FIGS. 8 and 9 another electric cable assembly with a variety of inner cable assemblies having same purpose is shown. FIGS. 8 and 9 have a cable jacket  78  and at least one abrasive resistance groove and/or refillable groove  80  containing the visually reacting and/or attention getting and/or protective material  83  which is overlaid by an optional transparent layer of protective coating  82  which may also be abrasive resistant at  81  by being inside of groove or indentation  80 , and still covering the visually reacting material  83  making a viewing lens also. This electrical cable assembly also includes at least one cable getting gatherer or string cable strengthener or cable filler or cable separator indicated by number  84  which may be comprised of thermochromic: paper, textile fabric or rubber. Also included may be an inner cable assembly of thermochromic impregnated insulation  86  at X and/or liquid crystal  88  at Y over which there is a, not necessarily, clear protective coating  90  because of being in an insulating housing  79  or having an outer jacket  78 . Alternately at Z  86  may be a conventional insulation with a simple coating of liquid crystals  88 .

Also referring to FIG. 14, a heat shrinkable tape  138  for any electrical cable assembly not of this patent application. 
     Referring to FIG. 15, there is an electrical cable assembly that may include any features of FIGS. 1 through 17 including  17 . In FIG. 15 there is a conductive element  142 , surrounded by insulation  144 , and an exploded view of a layer of visually reacting material  146  which is covered by a transparent protective cover  148 . Visually reacting materials which are sensitive to different temperatures or some physical component of electrical energy whether directly or indirectly, are separated by separations as at  150 , so that different sections of different types of visually reacting material will indicate increases or decreased in temperature, or increments of electrical faults, or overload conditions by movement of the visually activated section of the cable. Preferably adjacent sections blending or over-lapping into one another will contain materials which are visually reacting in adjacent temperature ranges, or increments of electrical faults, or over load conditions so that said changes in temperature and so forth will be most likely to give a clear appearance of movement. It will also be seen that the separations between the various visually reacting materials may be arranged transversely as in section  152 , these separations may be arranged to give the appearance of bands in/or on the cable jacket and to create the appearance of longitudinal movement. Examples of possible temperature ranges at which materials in these bands would be activated are also shown in section  152 . Coatings or layers of different types of visually reacting material or thermochromic ink may also be included in the form of lettering as in section  154  where possible temperature ranges for activation are also shown. Separations may also be arranged longitudinally as is shown in section  156 , where possible temperatures changes for activation are also shown to create the appearance of a colored strip having rotational movement around cable or give the illusion of the cable rolling. Finally as is shown in section  158  a background of coating applied with lettering coating may also be established by concentric layers as was shown in FIG. 3 to indicate increments of temperatures or electrical faults, in section  154 . Possible ranges for activation of the visually reacting materials in those ranges is also shown at  158 . Cable assembly may be designed to have separate features separately, or in some combination. Temperature ranges that are in FIG. 15 are there for example only. 
     Referring to FIG. 16, there is an electrical cable assembly that may include any features of FIGS. 1 through 17 including  17 . In FIG. 16 there is a conductive medium  160 , surrounded by insulation  162 , and visually reacting material  164  that may be impregnated into the insulation  162  which is covered by a transparent protective cover  166 . On the transparent protective over  116 , there is lettering with holographic ink as at  168  which may be a coating thickness layer of visually reacting material which indicates the presence of an electrical malfunction. Over his lettering there is a transparent protective covering of holographic film  170 . Also referring to FIG. 16 a conductor  160  surrounded by a principle insulation  162  with a luminescence, or non-changing color and/or descriptive terminology added at  164  and  168  with a thermochromic material that changes from same dark color or opaque at normal electrical conditions, to having transparency during abnormal electrical conditions at  166 , which is protected with an optional protective covering at  170 . 
     Referring to FIG. 17, FIG. 17 is an electric cabling assembly that may include any features of FIGS. 1 through 17 including  17 . In FIG. 17 there is a conductive medium at  172 , surrounded by insulation  174 , and visually reacting materials in the form of understandable language  176  which may be visual information or descriptive terminology  176 , which is covered by a transparent protective cover  178 . On the insulation  174  some of the visually reacting material reacts temporary as at  182 , some of the visual reacting material may react permanently as at  188  and  190 , because the visually reacting material is the same color as the insulation  174 , and if the insulation  174  were a different color, then a drop back would be needed surrounding insulation  174  so as to camouflage, the understandable language  176  this makes a camouflage means, that would be printed on the drop back. The understandable language  176  is not seen, until activation occurs at a predetermined electrical and/or thermal condition, for example the phrase at  184  may appear before  186 . The phrases of  188  and  190  could be last to appear if harmful electric condition were not corrected. Likewise, in FIG. 17 the insulation  174  may be impregnated and or covered with a visual reactive material, then an understandable language  176  printed on with normal ink, being both the same color, again phrases would be camouflaged until a predetermined electrical and/or thermal condition was to occur for activation of  176  phrases this also makes a camouflage means. In both processes an optional transparent protective cover could be tinted to aid the visual results. In both processes it may be desirable to employ the use of a visual and/or heat retardant or inhibitor, to be an ingredient in any of the visual reacting material  176  and/or the insulation  174 , in order to predetermine the timing or occurrence of the visual activation process, and/or rate of visual activation duration. The mass at a cable assembly would also be another factor. In both processes some of the understandable language  176 , may be designed to disappear. An example is the word normal, which may contrast the background at  174  during normal conditions and then camouflage itself into the background or dropback of  174  either temporary and/or permanently at predetermined conditions, in predetermined fashions. In both processes and other Figures of this patent, an artificial background may be needed to cover the outside of insulation  174  to aid visual result, if the insulation is not of a suitable natural color. 
     Referring to FIGS. 1,  2 ,  3 ,  9 ,  13 ,  14 ,  15 ,  16 ,  17  some General rules for building reacting insulated electrical cables. If an attention getting material having some response triggered at some predetermined hazard, has a high enough insulating value, the right durability factors, flexibility, and meets all proper electrical or insulating standards. It may be used solely as insulating means coupled directly to a conductor, and should handle without reacting to processes of normal electrical conduction by the conductor. In cases where an attention getting material does not always meet the standards required for an electrical cable assembly, it will then have to be a structure comprisement, or a consistent of a known insulation that does, and will still meet the required standards after that manipulation. Depending on the environmental influences to attention getting material would warrant or not, the use of a protective cover, that would have a means to release the responses of the attention getting material.
