External semiconductive layer peelable semi-conductive water-crosslinkable resin composition of the water cross-linked polyethylene insulated power cable

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for an external semiconductor layer of a water crosslinked polyethylene insulating power cable superior in heat resistance and tensile strength, and to provide the water crosslinked polyethylene insulating power cable manufactured by using it. ;SOLUTION: An external semiconductive layer of a water crosslinked polyethylene insulating power cable which has an internal semiconductive layer, a water crosslinked polyethylene insulating layer, an external semiconductor layer and a jacket layer formed on a conductor from inside to outside is formed of a separative semiconductive water crosslinked resin composition consisting of specified amount of (a) specified ethylene-vinyl acetate copolymer, (b) specified polypropylene, (c) specified organopolysiloxane, (d) carbon black, (e) unsaturated alcoxysilane, (f) organic peroxide, and (g) silanol condensed catalyst, and the water crosslinked polyethylene insulating power cable is manufactured by using the resin composition.;COPYRIGHT: (C)2001,JPO
