Abstract: An elastomeric material for providing electrical stress control comprises 5 to 40 volume percent low structured carbon black, 0.5 to 10 volume percent of high structured carbon black, up to about 30 volume percent of high permittivity inorganic fillers, and a remainder of polymeric carrier material and functional additives.

Abstract: A multi-layer heat-shrinkable tubular sleeve (100) comprises an outer layer (110) and an inner layer (120). The outer layer (110) is arranged around the inner layer (120). The outer layer (110) comprises a partially crystalline thermoplastic material with a major part of partially crystalline thermoplastic material with a crystallinity of more than 60%. The inner layer (120) comprises a partially crystalline thermoplastic material or an elastomeric material.

Abstract: A covered cable assembly includes a cable and a sealing assembly. The cable includes a metal sheath and a cable core. The metal sheath has a sheath terminal edge defining a sheath opening. The cable core extends through the metal sheath. The cable core includes an electrical conductor and an oil-impregnated paper insulation layer surrounding the electrical conductor. An extended cable core section of the cable core extends through the sheath opening and beyond the sheath terminal edge. The sealing assembly includes an oil barrier tube, a sealing mastic and a pressure retention tape. The oil barrier tube surrounds the extended cable core section. The sealing mastic surrounds the cable about the sheath terminal edge and overlaps portions of the metal sheath and the oil barrier tube adjacent the sheath terminal edge to effect an oil barrier seal between the metal sheath and the cable core at the sheath opening. The pressure retention tape surrounds the sealing mastic to limit displacement of the sealing mastic.

Abstract: A method of assembly is disclosed comprising the steps of collocating a plurality of individual cables in a first elastomeric tube held in a stretched condition by an engaged hold-out mechanism and disengaging the hold-out mechanism causing the elastomeric tube to contract and to urge the cables together. The resultant cable assembly is also disclosed and comprises a plurality of individual cables urged together by a first elastomeric tube coupled to a disengaged hold-out mechanism.

Abstract: A heat-shrink tube for an electrical power cable comprises a sleeve having an insulating inner layer, a conductive outer layer and a thermoplastic mid-layer located between the inner and outer layers. The mid-layer is recovered by the application of heat thereto. The insulating inner layer is preferably comprised of an elastomeric material and the thermoplastic mid-layer is rigid and acts to retain the inner layer in a radially expanded state prior to its recovery.

Abstract: A sheet-like electrical stress control article includes at least one void-filling layer of elastomeric void-filling material having some electrical stress control functionality (for example, containing 20 to 70% by weight of electrically conductive or semi-conductive fillers) and at least one support layer of elastomeric material selected and/or formulated (for example, with 45 to 65% by weight fillers) to require increasing applied stress to produce therein a given unit of strain as it approaches its break point The thickness and composition of the respective layers are selected so that the article is stretchable during application thereof to parts of a cable and the increasing stress required to stretch the support layer resists over-elongation of the void-filling layer.
