ABSTRACT:
A mandrel having a tapered surface expanding from a first dimension at a first end to a larger dimension at its second, and having a central bore larger than the diameter of a high voltage cable, is forced into the bore of a premolded or extruded high voltage component to expand, at least a portion of such bore to the diameters of such mandrel. A locking device is fixed to the component to retain the mandrel in place and retain the premolded or extruded component in its expanded state. In use the cable is inserted through the mandrel bore into the cover bore and the locking device released. As the cover returns substantially to its former dimensions, the hoops forces applied to the tapered mandrel force the mandrel out from the cover bore and it may be removed from the cable if desired.
