Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To provide a connection for a power cable having stable characteristics, which is capable of reducing deformation in a cable insulator and maintaining precise boundary pressure, by ensuring that the expansion of a pre-molded insulator is likely to escape in the longitudinal direction. SOLUTION: The pre-molded insulator inserted into between an epoxy unit (or porcelain tube) and the cable insulator is pushed in from the rear side by push hardware, and thereby the mated faces of the pre-molded insulator and the epoxy unit and the mated faces of the pre-molded insulator and the cable insulator are pressed against each other and brought into tight contact. In this structure, the flat portion formed on the periphery of the pre-molded insulator is reduced in outside diameter and the flat portion is positively moved away from the epoxy unit, so that a gap can be ensured between the peripheral flat portion of the pre-molded insulator expanded during temperature rise and the inner face of the epoxy unit. Thus, it is not caught in the radial direction and the expansion can escape in the longitudinal direction, that is, in the direction of the axis of the cable.  The flat portion, small in outside diameter, preferably comprises steps formed out of the conductive layer of the pre-molded insulator to which no electric field is applied.
