  • Patent number: 4494890
    Abstract: A connector for high tensile load attachment to an elongated rod, such as a resin bonded, glass reinforced rod, includes a high strength, elongated, metal cylindrical retainer having an internal shoulder formed at one longitudinal end and a plurality of outer peripheral threads formed at the other longitudinal end for the threaded attachment of a hook or other load bearing device. The connector further includes a plurality of metal collets or rings, whose inner peripheral profile configurations are that of a pair of truncated cones placed base-to-base, serially, longitudinally received within the retainer. The slopes of the cones of the collets received within the retainer are independently, variably preselectable to achieve optimum results. The junctions or edges defining the intersections of the bases of the cones are rounded off to avoid excessive stresses being transmitted to the rod.

The connector further includes a plurality of metal collets or rings, whose inner peripheral profile configurations are that of a pair of truncated cones placed base-to-base, serially, longitudinally received within the retainer. An organic potting compound, for example an epoxy resin, is poured into the space between the rod and the collets and is allowed to cure.

  • Patent number: 4223179
    Abstract: A cable termination connector assembly for physically receiving and securely retaining the bared end of a current carrying center conductor of a high voltage power cable and for making an external electrical connection to the center conductor includes a multi-barrel connector for use with many different sizes of high voltage power cables. A plurality of elongated, generally axially extending apertures are formed in the connector for receiving the wire strands of a segmented or nonsegmented center conductor of a high voltage power cable. In a specific embodiment, the apertures are canted or inclined with respect to the longitudinal axis of the center conductor and the multi-barrel connector to minimize the length of cable insulation that is cut away or stripped back and thereby increase the dielectric strength or reduce the size of the termination assembly and facilitate insertion of the wire strands.

  • Patent number: 4212696
    Abstract: An organic composite electrical insulator system includes one or more modular ethylene propylene copolymer elastomeric molded insulators or sheds bonded by a thin line bond to an epoxy or polyester resin bonded fiberglass structural member. In one embodiment, the organic composite insulator system may take the form of a suspension insulator used to support a high voltage power cable from a transmission tower. The suspension insulator includes a pair of metallic end connectors mechanically attached to opposite longitudinal ends of an elongated polyester resin bonded fiberglass core rod. The space between the end connectors along the rod is filled with a plurality of modular ethylene propylene elastomeric molded insulators or sheds having inner diameters smaller than the outside diameter of the rod in order to obtain a slip fit and thereby compressively load the interface surfaces between the sheds and the rod during the manufacture of the rod.

  • Patent number: 4198538
    Abstract: A suspension insulator for supporting a high voltage power cable suspended from a transmission tower includes an elongated rod for supporting a load in tension, a plurality of insulating shells serially disposed along the rod and end connectors for attaching a high tension load to the rod. At least one of the end connectors includes an elongated metal cylindrical retainer having one or more metallic members with one or more inclined surfaces disposed within the retainer and circumferentially disposed around the rod. The space between the inclined surface or surfaces and the rod is filled by an epoxy resin compound.In order to prevent excessive heating of the compound due to external flashover of the suspension insulator and the possible resultant separation of the end connector from the rod, the suspension insulator includes a generally cylindrically shaped, electrically conductive, current bypass sleeve disposed about the retainer to provide a current path physically remote from the epoxy resin compound.

  • Patent number: 4133970
    Abstract: An electrical insulation system includes a new and improved monolithic, polymeric, porous, open cell, fully impregnable, dielectric solid and an impregnating substance that may be applied to the dielectric solid either at the factory prior to shipment or in the field prior to or during installation. The dielectric solid is preformed to enable the quick and easy field installation of the insulation system in electrical apparatus. In addition, the porous, open cell nature of the dielectric solid in which very small communicating open cells are substantially evenly distributed throughout substantially all of the dielectric solid enables a dielectric fluid, such as a dielectric oil, to pass through the dielectric solid and thereby impart the self-healing characteristic of impregnated layered paper insulation to the new and improved insulation system. In a fluid dielectric system, the impregnating substance may be a dielectric oil or other dielectric liquid.

  • Patent number: 4079186
    Abstract: An entrance fitting assembly is disposed at an interface between a high voltage power cable and a high pressure oil filled cable termination to physically and electrically terminate the power cable skid wires, to seal the power cable pipe system to the cable termination and to filter the dielectric liquid flowing between the power cable pipe system and the cable termination. The entrance fitting assembly includes a centering and support plate for receiving and securing the cable skid wires, an elastomeric semi-stop or oil seal and an oil filter. In accordance with a preferred embodiment of the present invention, the oil filter is formed by a monolithic, polymeric, porous, open cell solid in a configuration of a thin annular disc.

  • Patent number: 4046958
    Abstract: A cable termination connector assembly for physically receiving and securely retaining the bared end of a current carrying center conductor of a high voltage power cable and for making an external electrical connection to the center conductor includes a multi-barrel connector for use with many different sizes of high voltage power cables. In a specific embodiment, four, elongated, axially extending apertures are formed in the connector for receiving the wire strands of a segmented or nonsegmented center conductor of a high voltage power cable. For smaller power cables, only one or two of the four apertures may be used; for larger power cables, three or four of the apertures may be used.
