Title:
POWER CABLE
Document Type and Number:
WIPO Patent Application WO/2018/135700
Kind Code:
A1
Abstract:
The present invention relates to a direct current power transmission cable, particularly, an extra-high voltage underground or submarine cable. Specifically, the present invention relates to a power cable which: can suppress the occurrence of a deoiled void in an insulation layer and the like to suppress partial discharge, dielectric breakdown, etc., which may be caused by an electric field concentrated on the void, and thus extends lifespan of the cable; can effectively prevent degradation of dielectric strength, which may be caused by permeation of copper powder from a copper conductor into the insulation layer, and thus additionally extends lifespan of the cable; can restrain the damage of an insulation sheet, a semi-conductive film, etc. in spite of repetitive bending and unbending, thereby maintaining an interlayer structure formed by winding thereof; and can have improved flexibility and workability, and an improved bending property and pulling installation property, etc.
