Abstract

Method of manufacturing an electric cable that has a metallic core and one or more metallic shields and is provided, between this core and the metallic shield or between two consecutive metallic shields, with at least one layer of electrically semiconductor material and a layer of Electrically insulating material easily separable from each other, characterized in that it comprises: preparing an electrically insulating composition, based on polyethylene or a crosslinkable ethylene copolymer and an electrically semiconductor composition based on crosslinkable polyethylene chlorosulfonate; simultaneously placing these two compositions between the metal core and the metal screen or between two consecutive metal screens of said cable, in the form of an insulating layer and a semiconductor layer respectively; and carrying out a heat treatment that performs a simultaneous crosslinking of the two layers.
