INSULATED ELECTRICAL CONDUCTOR

摘要

. An insulated electrical conductor having outstanding elevated temperature properties comprising a conductor coated with an extruded first and second layer of crosslinked polymeric insulation material. The first layer is a crosslinked polyolefin. The second layer surrounds the first layer and comprises a crosslinked copolymer of ethylene and chlorotrifluoroethylene containing from 1 - 10% by weight of the copolymer of a crosslinking coreactant selected from the group consisting of (a) diallyl, dimethallyl and dimethallyl esters of alkyl, cycloalkyl and aralkyl dicarboxylic acids, (c) dimethacrylate glycol esters and (d) blends of said crosslinking coreactants and from 1 to 10% by weight of the copolymer of a stabilizer selected from the group consisting of alkaline earth metal oxides and lead salts.
