Abstract:
1. A multi-conductor cable adapted for use, particularly, in a mechanical cable track, wherein the cable is subjected to contraction in the extension mode of the track, and a wiping or milking action is applied to the outer contact surface of the cable, the cable comprising: two or more insulated conductors, the conductors are 20 AWG or larger in size; and a dual layer jacket, the dual layer jacket having an inner layer jacket having a thermoplastic elastomer having a tensile modulus of at least 1550 psi to resist stretching forces externally applied to the cable, and an outer layer jacket having a thermoplastic elastomer having a tensile modulus no greater than 1300 psi, wherein the inner layer and outer layer are co-extruded, which co-extrusion naturally forms distinct, but inseparable layers as between the inner and outer layer jackets without the need for adhesives or bonding agents, which cable exhibits flexibility, and can withstand prolonged exposure to −40° C. temperatures.
