Abstract
Abstract A cable sealing end includes a base fitting configured for mounting on a base; a top fitting configured for securing an overhead conductor; an insulating body made of polymeric material; a conductive connection device configured to form a connection between a cable conductor and the top fitting; and a supporting element. The supporting element includes an elongated metal body; a top plate disposed on the elongated metal body and securable to the top fitting; and a metallic cylindrical structural component. The structural component projects into an interior of the insulating body and has a base flange disposed adjacent to the base fitting. The structural component has a length of one quarter to one third of a length of the insulating body. An entire length of the elongated metal body and the structural component, with the exception of the base flange, are embedded in the insulating body.
