Abstract:
1. A fiber reinforced plastic wire for a strength member of an overhead transmission cable, comprising: a wire having a predetermined diameter and composed of thermoset matrix resin; and a plurality of high strength fibers dispersed parallel to a longitudinal direction in an inside of the wire, wherein the high strength fibers are surface-treated with a coupling agent by immersing high strength fiber strands in a coupling agent solution that comprises the coupling agent and a solvent, agitating the high strength fiber strands, removing the solvent from the plurality of high strength fiber strands, applying ultrasonic waves to the high strength fiber strands, immersing the high strength fibers into an uncured composition of the thermoset matrix resin and cooling the thermoset matrix resin to improve interfacial adhesion to the matrix resin.
