  • Publication number: 20170207617
    Abstract: A dry power cable termination has an insulation sleeve, a silicone rubber tube and a stress control cone. The insulation sleeve has an inlet and an outlet opposite to the inlet. The silicone rubber tube is disposed over an exterior of the insulation sleeve; and the stress control cone is received within the insulation sleeve. A power cable is inserted from the inlet of the insulation sleeve and extends out from the outlet of the insulation sleeve. The stress control cone is fitted over the power cable so as to prevent a local electric field concentration from occurring at a cutting end surface. The dry power cable termination furthermore has a shielding sleeve, an electrode, an electric connection assembly and a clamping pipe. The shielding sleeve is received within the insulation sleeve and fitted over an exposed segment of an insulation layer of the power cable.

  • Publication number: 20170085075
    Abstract: A pre-expanded cover assembly for protecting a cable splice connection including a cable, the cable including an electrical conductor surrounded by a cable insulation layer, includes a splice body assembly and a removable holdout. The splice body assembly includes a tubular, cold-shrinkable, electrically insulative, elastomeric splice body having an interior surface defining an interior passage. The splice body assembly further includes a tubular layer of a conformable medium pre-mounted on the interior surface of the splice body. The conformable medium is a flowable material having a high electrical permittivity. The splice body assembly is mounted on the holdout such that the holdout maintains the splice body in an elastically radially expanded state, and the holdout is selectively removable from the splice body to permit the splice body to elastically radially contract.

  • Patent number: 9343882
    Abstract: The disclosed power cable enables optical fibers to be installed after the power cable has been installed, thereby forming a hybrid cable. Segments of the power cable are manufactured with fiber installation tubes containing pulling members. When the power cable segments are coupled together, the fiber installation tubes and pulling members also are coupled together to form a fiber installation conduit and an extended pulling member. A fiber pull arrangement can be coupled to the extended pulling member and drawn through the fiber installation conduit within the power cable at any time subsequent to installation of the power cable.

  • Publication number: 20160036213
    Abstract: A cold shrinkable termination for an electric power cable that includes an insulation tube and stress control glue. When the cold shrinkable termination is mounted on the electric power cable, the stress control glue fills a gap between the electric power cable and the insulation tube so as to prevent local electric field concentration from occurring at an exposed end of the electric power cable. The stress control glue has a dielectric constant within a range of 5 to 100. In this cold shrinkable termination, a stress control glue with high dielectric constant is provided to optimize the electric-field distribution on an insulation surface of the electric power cable. Thereby, the structure of the cold shrinkable termination is simplified and the cost thereof is reduced. The cold shrinkable termination may be adapted to an electric power cable used to transmit voltage less than 26/35 kV.
