ABSTRACT:
An electric power cable line is arranged in which the insulating layer is increased to a greater thickness at two end portions of each cable than a thickness at the other or center portion of the same. Since the insulating layer is increased in thickness at the end portions of the cable, thus an electrical stress exerted on the overall layer construction of the end portions is lowered. Hence, the dielectric strength of the end portions of the cable becomes high and the power cable line will thus be increased in the operational reliability.
