An electric power cable line and a method of fabricating the same.

摘要

An electric power cable line is arranged in which the insulating layer (16) is increased to a greater thickness (T2) at two end portions (42) of each cable (40) than a thickness (T1) at the other or center portion of the same. Since the insulating layer is increased in thickness at the end portions (42) of the cable (40), thus an electrical stress exerted on the overall layer construction of the end portions (42) is lowered. Hence, the dielectric strength of the end portions (42) of the cable (40) becomes high and the power cable line will thus be increased in the operational reliability. <IMAGE>
