<p>PROBLEM TO BE SOLVED: To provide a power cable with high heat-resistance, a high extrusion molding property, high water-tree resistance, and having an insulator with a high peeling-off property, high recovering workability, and high recyclability. SOLUTION: A power cable has a conductor 1, an inner semi-conductive layer 2b, and an insulator 3b, and the inner semi-conductive layer 2b is made of high molecular weight ethylene-vinyl acetate copolymer, semi-conductive carbon black, etc., and the insulator 3b is made of straight-chain polyethylene having a melt tension of 3 g or more and a melting point of 120 deg. or higher.</p> |
