THE PROCESS FOR FORMING AN INSULATED ELECTRICAL CONDUCTOR WHICH COMPRISES (1) APPLYING AROUND AN ELECTRICAL CONDUCTOR WRAPS OF AN ORIENTED, STRETCHED POLYOLEFIN CROSSLINKED BY IRRADIATION WITH HIGH ENERGY ELECTRONS, THERE BEING INTERPOSED BETWEEN THE WRAPS OF SAID ORIENTED, STRETCHED POLYOLEFIN AND THE SURFACE OF SAID ELECTRICAL CONDUCTOR A LAYER OF THERMOPLASTIC POLYOLEFIN HAVING A SOFTENING POINT ABOVE 80*C. AND (2) HEATING THE RESULTING ASSEMBLY AT A TEMPERATURE ABOVE THE SOFTENING POINT OF SAID THERMOPLASTIC POLYOLEFIN AND IN THE RANGE IN WHICH SAID ORIENTED, STRETCHED POLYOLEFIN TENDS TO SHRINK TO EFFECT SHRINKAGE OF SAID ORIENTED, STRETCHED POLYOLEFIN, THEREBY CAUSING MIGRATION OF SAID THERMOPLASTIC POLYOLEFIN TO FILL IN THE VOIDS USUALLY PRESENT WHEN SAID ORIENTED, STRETCHED POLYOLEFIN IS HEATED AND SHRUNK IN THE ABSENCE OF SAID THERMOPLASTIC POLYOLEFIN.
