ABSTRACT:
A joint between high voltage cables is formed by employing a connector having the same diameter as the cable dielectric. A layer of stress controlling material extends from the cable screen on one side of the joint, along the cable dielectric, across the connector, along the dielectric of the other cable and on to the screen of the other cable. A layer of conducting material extends on top of the stress controlling layer and longitudinally encompasses the conductor connector and overlaps the dielectric of both cables. An insulating layer encloses the conductive layer. Further layers of conductive and/or stress controlling material may be applied around the joint. In addition to being used in the formation of a joint between high voltage cables, a layer of stress controlling material with a layer of conducting material on its outer surface is employed in forming a termination of a high voltage cable.
