Abstract: A method and means are disclosed for dissipating heat in a high voltage cable termination which includes a plurality of axially stacked annular capacitor elements disposed coaxially over the prepared end of a high voltage cable and disposed within an annular insulator so that a temperature gradient normally exists radially across the capacitor elements. A thermally and electrically conductive annular disc is interposed between each adjacent pair of stacked capacitors for dissipating heat from the area inwardly of the capacitors to the area outwardly thereof. The conductive discs enable a significantly greater increase in terminator ampacity, and may be employed in both AC and DC high voltage systems.

Abstract: An internal shield ring for the air entrance bushing of a gas-insulated bus system tapers inwardly at its free end and has a reduced spacing with respect to the central bushing conductor to increase the dielectric stress between the end of the shield ring and the central bus. This reduces the stress on the external bushing insulation material and thus permits a reduction in the bushing diameter.

Abstract: A seal is used to prevent the escape of gas from a gas pressurized plastic-jacketed, multi-conductor cable where the conductors of an unjacketed portion of the cable enter a cabinet of a terminal which is exposed to temperature cycling. The seal includes a sleeve made of an elastomeric material having one end which engages an end section of the cable jacket with the conductors of the unjacketed portion of the cable extending through the other end of the sleeve into the cabinet. The seal also includes a metallic tube which is disposed about the elastomeric sleeve with one of the end portions of the tube which is aligned with the cable jacket being in compressive engagement with the sleeve and jacket. A plugging compound in the other end portion of the tube and which is compliant with the sleeve material encapsulates the conductors and the other end of the sleeve which extends into the plugging compound.

Abstract: A coaxial, hermetically sealed end structure is described for electrical instrumentation cables. A generally tubular ceramic body is hermetically sealed within a tubular sheath which is in turn sealed to the cable sheath. One end of the elongated tubular ceramic insulator is sealed to a metal end cap. The other end of the elongated tubular insulator has an end surface which is shaped concave relative to a central conductor which extends out of this end surface. When the end seal is hermetically sealed to an instrumentation cable device and the central conductor is maintained at a high positive potential relative to the tubular metal sheath, the electric field between the central conductor and the outer sheath tends to collect electrons from the concave end surface of the insulator. This minimizes breakdown pulse noise generation when instrumentation potentials are applied to the central conductor.

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.

Abstract: This kickless water-cooled resistance welding cable consists of an elongated elastomeric hose containing two pairs of stranded copper wire conductors or "ropes" of opposite alternating polarities mounted in the four peripheral grooves of an elongated elastomeric separator of cruciform cross-section with a central cooling water passageway therethrough. These grooves are of circular cross-section such that when the separator is twisted longitudinally the groove side walls compress and tightly grip the conductors while these are cooled by water flowing into the grooves through perforations from the passageway. The conductors are connected at their opposite ends to copper terminals, each of which includes a pair of elongated semi-cylindrical copper terminal halves with an insulating strip between them and with two pairs of circumferentially-spaced bosses containing cable conductor sockets arranged in alternating polarity.

A pulling eye is provided having a passageway formed generally coaxially within a shank portion thereof and extending to the body of the eye wherein a transversely disposed threaded opening is formed to communicate with the coaxial passageway. The shank is threaded for mating engagement within complementary threads formed in the second axial end of the shell. Stainless steel tubing, or the like, is soldered within the coaxial passageway of the pulling eye.

The shell is crimped onto the conductors and the stripped portions of the cable repositioned over the shell.

Abstract: An internally cooled high-energy cable is equipped with terminal connector assemblies for supplying electric current thereto and withdrawing the current therefrom, and with terminal connector assemblies for supplying a cooling medium to the cable and discharging the spent cooling medium therefrom. A connecting pipe connects the two assemblies at each end of the cable and conducts the cooling medium from one to the other. The flow-through cross section of the channel for conducting the cooling medium through the cooling medium terminal connector assembly is smaller than the flow-through cross section of the cooling channel of the cable which results in more rapid flow of the cooling medium through the former channel and in enhanced cooling effect, so that the heat resulting from the decline in the electric potential of the cooling medium in the cooling medium terminal connector assembly is effectively dissipated.
