POWER CABLE
Document Type and Number:
WIPO Patent Application WO/2018/174330
Kind Code:
A1
Abstract:
The present invention relates to a power cable and, in particular, to an underground or undersea cable for long-distance ultrahigh-voltage direct current transmission. Specifically, the present invention relates to a power cable wherein an insulation layer itself has high dielectric strength, an electric field applied to the insulation layer is effectively alleviated, and particularly when, after the power cable is installed under a low temperature environment, the power cable is left at a low temperature for a long period of time until current flows therethrough, occurrence of a large void in the insulation layer is suppressed, so that partial discharge, dielectric breakdown, and the like due to electric fields concentrated in the void can be effectively prevented.
