Abstract

Improvements in or relating to fittings or terminations for electrical conductors characterized by the method of covering a joint or termination between electrical conductors which comprises slightly irradiating a length of polyethylene or polypropylene tube, heating the irradiated tube above the melting point of plastic which has not been subjected to irradiation, deform said length of tube, place it on the joint or termination and heat the tube to make it adopt its original shape and shrink on the joint.
