Abstract
Abstract A cable termination assembly for terminating a high voltage current-carrying conductor includes an outer porcelain housing and an inner polymeric liner of low durometer, cast in the housing before insertion of the cable. The liner is bonded to the housing wall to prevent air voids. A metal base member amy be employed and may include an upstanding shielding collar extending part way into the housing and being joined thereto by the cast liner.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
A cable termination apparatus for terminating a cable including current carrying conductor means having an outer cable insulation means, comprising: a rigid housing having an inner bore wall defining an inner bore; a substantially incompressible, but nonetheless deformable flexible on-piece hollow liner of cast polymeric material having a liner bore wall defining an inner conductor-receiving bore of smaller size than the cable insulation means, the liner bore wall having an enlarged entrance end and an upper end which is enlarged to accommodate liner material displaced toward the upper end of the liner bore wall when the conductor means is inserted in the entrance end of the liner bore wall; and said liner being in continuous intimate contact with the inner bore wall of said housing so as to substantially eliminate voids at the interface between said liner and said inner bore wall.
