A METHOD OF APPLYING A SYNTHETIC PLASTCI COVERING TO AN ELECTRIC CABLE WITH A POLYOLEFIN COVERING.

摘要

A method of applying a covering to an electric cable having an outer layer consisting of a polyolefin, in which a layer of cross-linkable or vulcanizable olefinic co polymer of at least two olefins is provided on said layer consisting of polyoiefin, a tubular body consisting of thermally conductive material particularly a metal, is placed around said layers and said tubular body is heated so as to effect vulcanisation of cross-linking of the copolymer layer, and wherein said tubular body is made of two half shells having peripherally extending external grooves.
