摘要

A DC high-voltage wire comprising: a conductor; a resin composition layer coating the conductor, the resin compsotion layer comprising a polyolefin resin containing carbon black in an amount of not less than 10 parts by weight per 100 parts by weight of the polyolefin resin, having an insulation resistance of not more than 10<1><0> OMEGA .cm; an insulating layer coating the resin compsition layer, the insulation layer comprising polyethylene having a softening temperature of not lower than 105 DEG C; and a fire retardant protective coating layer coating the insulating layer, the fire retardant protective coating layer comprising (1) a terpolymer of ethylene, vinyl acetate and vinyl chloride, and/or a terpolymer of ethylene, methyl methacrylate and vinyl chloride, and (2) a copolymer of chlorinated ethylene and vinyl chloride; the resin composition layer, the insulating layer and the fire retardant protective coating layer each being crosslinked.
