Abstract
A semi-conductive tubular assembly ( ) or molded rubber cap is used in a cable joint for medium voltage electric power cables ( ). The conductors ( ) of the cables are connected together by a connector ( ) constituted by a bolted contact assembly having a tubular shape and wherein the conductor ends are maintained by bolts. Two rubber caps ( ) preferably overlap each other in the middle of the connector. Each cap has an internal shape adapted to compensate for the gap resulting from the difference in diameter between the conductor insulation and the connector, as well as for the eccentric position of the latter with respect to the conductors. By mating the change of shape ( ) between the underlying connector ( ) and the conductor insulation ( ), the caps provide a relatively cheap and efficient solution for an electrically reliable product, e.g. by reducing local electric stresses. In addition covering the sharp edges, mainly of the underlying connector, the molded rubber cap has an outer surface that provides a conical transition with a relatively slow slope for smoothing the above diameter transition.
