    Abstract: Disclosed is a fiber reinforced plastic wire used as the overhead transmission cable. The fiber reinforced plastic wire for a strength member of an overhead transmission cable according to the present invention includes 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, the high strength fibers being surface-treated with a coupling agent to improve interfacial adhesion to the matrix resin. The fiber reinforced plastic wire of the present invention has the high tensile strength at the room temperature and the high temperature since its high strength fiber is surface-treated with a coupling agent. The fiber reinforced plastic wire can be also effectively used as the strength member in the overhead transmission cable since it has the excellent low coefficient of thermal expansion, etc. and is light-weight.

    Abstract: The disclosed method of making a shape-stranded rope includes twisting large wires into strands by twining them in at least one layer about a core with a sheathing of a soft deformable material, plastic drawing of the strands, forming the strands into a shaped profile and twisting the strands into the rope. The plastic drawing is effected until every round wire of the strand acquires a wedge-like profile, with the wires adjoining the sheathing becoming partly embedded in this sheathing, and the strand acquires a substantially smooth peripheral surface. The method enables, while using round wires, to increase the structural density of the strands, and also to enhance the flexibility, strength and wear resistance of the shape-stranded rope, the rope manufactured by the disclosed method being usable by various industries.
