Abstract: An electric cable joint arrangement includes two cables each having a cable end. Each cable has a metallic conductor surrounded by extruded polymeric insulation. Contiguous ends of the conductors are aligned and connected together by a joint, a screen extending over the joint, and a resilient insulating body shrunk onto the insulation to insulate the joint arrangement. At least one pin extends through a close-fitting bore in the insulation of each cable end and is embedded into the conductor. The screen extends over each pin. An associated method includes exposing insulation, forming at least one bore through the insulation, driving a pin through each bore until the pin is embedded into the conductor, aligning and connecting together ends of the metallic conductors, and providing a screen extending over a conductor joint and an area of each of the pin and a resilient insulating body shrunk onto the cable insulation.

Abstract: A composition of matter useful for strippable shields for electric power cables comprises:a base polymer which is a copolymer of ethylene with a mono-unsaturated ester;conductive carbon black in an amount to give the composition an electrical resistivity below 500 .OMEGA.m; andas adhesion-controlling additive, a copolymer of ethylene with a mono-unsaturated ester containing from 0.5 to 2% by weight of side-chains each of which comprises an inflexible ring structure bonded to a backbone carbon atom of the copolymer with at most five atoms interposed between them.The compositions have the advantage of being less rubbery than current strippable-screen compositions and can be made successfully with copolymers of lower ester content.
