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:
A steel cord is configured so that, when the steel cord is used as a tensile cord for an elastic crawler, a center-core dislocation and the earl y breakage of the wi res of a core are prevented. A steel cord comprises: a core which comprises a single core strand, and a sheath which is formed by twisting together six sheath strands arranged around the core. The core strand has a layer-twisted structure comprising: a center-core portion which is formed by twisting three core wires together; and an external layer portion which is formed by twisting together eight to nine core wires arranged around the center-core portion. The sheath strands each have either a bundle twisted structure which is formed by twisting twelve to nineteen sheath wires or a multi-layer twisted structure which is formed by twisting twelve to nineteen sheath wires in layers. The diameter (dc) of the core wires is greater than the diameter (ds) of the sheath wi res. The average gap (Gc) between the core wi res of the external layer portion is 0.015 mm or greater, and the average gap (Gs) between the sheath strands is 0.1 mm or greater.
