ABSTRACT:
Disclosed is a heat-resistant, high-voltage insulated lead wire for direct current, which meets the demand for higher heat resistance, and its insulating coating over the conductor is formed by a polyolefin resin composition. The polyolefin resin composition is a flame-retarded resin composition comprising of a mixture of a polyethylene whose crystalline component has melting point higher than 125.degree. C. and a copolymer of ethylene and .alpha.-olefin, which contains a multifunctionalized monomer having unsaturated carbon-carbon bond moiety in the molecule as an indispensable component. The insulating coating made of this resin composition is irradiated by an ionizing radiation to give a heat-resistant, high-voltage lead wire for direct current, which has a perpendicular flame resistance (VW-1) acceptable in the UL Standards and has a temperature rating of higher than 125.degree. C.
