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. A pair of oval point set screws associated with each of the apertures of the connector exert a high pressure to force the wire strands of the center conductor against the inner walls of the apertures to securely retain the wire strands within the connector and to break-up aluminum oxide coatings formed on the wire strands of aluminum center conductors. The connector assembly further includes a metallic cap plate that physically supports the multi-barrel connector and that provides an effective heat sink to maintain a uniform temperature throughout the duty cycle of the cable termination. The connector assembly also includes a connector housing that rests on the cap plate, that seals the connector and the interior of the cable termination and that supports a threaded connector stud for making an external electrical connection.
