Patent ID: 8371028

Claim:
A method for increasing the current carried between two high voltage conductor support towers, the method comprising: removing a first high voltage carrying cable having a weight suspended between the towers, said first cable having a steel core and an amount of a first conductor surrounding the core, wherein said first cable having an outer surface diameter; forming a second cable comprising a composite core, said forming comprising, commingling a thermoset or thermoplastic resin with reinforcing fibers, pultruding or extruding said commingled resin and fibers to form said composite core, hardening said composite core to form a solid composite core, and surrounding said solid composite core with a second conductor forming said second cable having an outer surface diameter, wherein the second conductor carries more electrical current than the first conductor, wherein the weight of the second cable is not greater than the weight of the first cable, and wherein the second conductor has a higher conductivity than the first conductor, and wherein an outer surface diameter of the composite core is smaller than an outer surface diameter of the steel core; and replacing said first high voltage carrying cable with the second cable on the towers such that the second cable is suspended between the towers, wherein said commingled resin and fibers are pultruded or extruded to form said core having sufficient length for forming the second cable having sufficient length for replacing said first cable.
