<p>PROBLEM TO BE SOLVED: To obtain a power cable with high heat-resistance, high flexibility, a high extrusion molding property, high water-tree resistance, and having a small shrink-back 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 and semi-conductive carbon black, and the insulator 3b is made of heat resisting straight-chain polyethylene formed by polymerizing ethylene, propylene, and butene-1.</p> |
