Method for increasing the current carried between two high voltage conductor support towers

1. 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,

comingling a thermoset or thermoplastic resin with reinforcing fibers,

pultruding or extruding said comingled 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 an amount of a second conductor greater than the amount of the first 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

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.

2. The method as recited in claim 1 wherein removing the first cable comprises removing the first cable using a set of tools, and wherein replacing the first high voltage carrying cable comprises mounting the second cable on said towers using a set of tools of the same type as the set of tools used to remove the first cable.

3. The method as recited in claim 1 wherein removing the first cable comprises removing the first cable using a set of tools, and wherein replacing the first high voltage carrying cable comprises mounting the second cable on said towers using tools from the same set of tools.

4. The method as recited in claim 1 wherein the second cable is mounted on a location on each tower previously occupied by the first cable.

5. The method as recited in claim 1 wherein an outer surface diameter of the composite core is smaller than an outer surface diameter of the steel core.

6. The method as recited in claim 1 wherein comingling comprises comingling strands or ropes of thermoplastic resin with said reinforcing fibers.

7. The method as recited in claim 1 wherein pultruding or extruding comprises pultruding said comingled resin and fibers to form said core.

8. The method as recited in claim 7 wherein said reinforcing fibers are selected from the group of fibers consisting essentially of glass, boron and carbon.

9. The method as recited in claim 1 wherein said reinforcing fibers are selected from the group of fibers consisting essentially of glass, boron and carbon.

10. The method as recited in claim 1 further comprising selecting transmission and distribution (T&D) accessories that are mountable on said first cable and mounting said accessories on the second cable.

11. The method as recited in claim 1 further comprising using the same tools to remove the first cable and to install the second cable.

12. The method as recited in claim 1 wherein the second conductor is smelted aluminum.

13. The method as recited in claim 1 , wherein the outer surface diameter of the second cable is the same as the outer surface diameter of the first cable.
