ABSTRACT:
Electrical cables having cross-linked polymer insulations are spliced by heating the insulations nearest the ends to be joined to a temperature such that the cross-linked polymers become amorphous, then expanding and axially moving the insulations away from the conductors such that they can be joined, then cooling the displaced insulations, then joining the conductors, and then reheating the insulations such that they return to generally their original shape and position around the conductors. The prior art technique of bevelling the insulators nearest the cable ends prior to conductor joining, with concurrent waste of insulating material, is made unnecessary.
