WIPO Patent Application WO/2018/151371
Kind Code:
A1
Abstract:
The present invention relates to a power cable, particularly, a super high-voltage underground or submarine cable for long-distance direct-current transmission. Specifically, the present invention relates to a power cable in which an insulation layer itself has high dielectric strength, an electric field applied to the insulation layer is effectively reduced, and, particularly under a low-temperature condition, a void is restrained from occurring in the insulation layer and semiconducting layers respectively arranged on the upper and the lower part of the insulation layer, thereby effectively restraining partial discharge, dielectric breakdown, etc. due to an electric field concentrated on the void.
