Electric wire and cable

摘要

An electric wire includes a conductor having a cross-sectional area of not less than 135 mm2 and not more than 165 mm2, an insulation provided so as to cover the outer periphery of the conductor, and a wire sheath provided so as to cover the outer periphery of the insulation. The amount of deflection is not less than 250 mm when, at 23° C., one end of the electric wire is fixed to a fixture table so that another end horizontally protrudes 400 mm from the fixture table and a weight of 2 kg is attached to the other end, and cracks and breaks do not occur when wound with a bending diameter of three times the diameter at −40° C.

1. An electric wire, comprising:
a conductor having a cross-sectional area of not less than 135 mm2 and not more than 165 mm2; an insulation provided so as to cover the outer periphery of the conductor; and a wire sheath provided so as to cover the outer periphery of the insulation, wherein the amount of deflection is not less than 250 mm when, at 23° C., one end of the electric wire is fixed to a fixture table so that another end horizontally protrudes 400 mm from the fixture table and a weight of 2 kg is attached to the other end, and cracks and breaks do not occur when wound with a bending diameter of three times the diameter at −40° C., wherein the insulation and the wire sheath comprise a resin composition comprising a base resin that contains 100 parts by weight in total of a chlorinated polyethylene with a chlorine content of not less than 30% and not more than 45% in an amount of not less than 20 parts by weight and not more than 60 parts by weight and a polyolefin resin other than the chlorinated polyethylene, and wherein the polyolefin resin is an ethylene-vinyl acetate copolymer.
