摘要： An electrical power cable with a stranded conductor, a semi-conductive stress control layer around the conductor, a layer of insulation around the stress control layer, a semi-conductive insulation shield layer around the layer of insulation, an imperforate metal strip with overlapping edge portions around the shield layer and a polymeric jacket around the metal strip. The strip is free to move with respect to the jacket and the shield layer with expansion and contraction of the cable elements with temperature changes, and the overlapping edge portions of the strip are bonded together by an adhesive which permits the edge portions to move relative to each other with such temperature changes without creating fluid passageways between the edge portions. A cushioning layer can be between the shield layer and the strip and preferably, the cable is water sealed.
