发明名称 Joint for low and medium voltage electric cables
摘要 A cable joint for joining the ends of two electric cables operating at voltages up to 60 kilovolts in which the bared conductor ends are conductively joined by a ferrule and the bared insulation of the two cables is at least partly covered by a pair of tight fitting elastomeric sleeves. The sleeves and the joined conductor ends are surrounded by a monolithic sleeve of dielectric material which tightly engages the elastomeric sleeves and which has a conductive, cylindrical electrode at its inner surface which surrounds at least the joined, bare conductors. Conductive rings on the conductors interconnect the conductors with the electrode. The monolithic sleeve is surrounded by a layer of semi-conductive material which interconnects the semi-conductive screens of the cables, and the semi-conductive layer may be surrounded by further layers for conductively interconnecting metal sheaths of the cables and for providing mechanical protection for the joint.
