  • 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: 3943315
    Abstract: An improved high-voltage circuit-interrupter of the gas-blast type is provided having improved gas-partitioning and particle-collecting means so provided as to prevent the entrance of small insulating, or metallic particles into the high-pressure storage chamber of the interrupter. A non-perforated insulating support member provides support for the high-voltage conductor, and, additionally, seals off the high-pressure gaseous storage region within the high-pressure chamber from the contact interrupting chamber, where, due to contact engagement and disengagement, relatively small metallic particles may be generated, and if allowed to wander into the high-pressure storage chamber provided between the high-voltage conductor and the outer grounded tube of the high-pressure storage chamber, would precipitate, or encourage high-voltage breakdown, or flashover between these two conducting members which are at widely-different voltages, say, for example, 200 K.V.
