ABSTRACT:
An apparatus and method for producing an insulated connection between a pair of insulated electrical cables by means of curing uncured insulation wrapped around joined conductors in the cables. The apparatus comprises a multiple part mold assembly having a cylindrical cavity, mechanisms for heating and cooling the mold parts and an assembly for creating a radially inwardly directed, substantially constant pressure on the curing insulation while allowing radial expansion and contraction of the insulation and mold parts during heating and cooling. The pressure-creating assembly comprises a pair of rectilinear power devices and a pair of cables wrapped around the mold parts and tensioned by the power devices, this assembly applying a radially inwardly directed, equal and substantially constant force to the mold parts. Preferably, the mold assembly comprises three equal parts, each defining one-third of a cylindrical body and each having rollers on the outer surface for receiving the cables therein.
