Title (EN) POWER CABLE
(FR) CÂBLE D'ALIMENTATION
(KO) 전력 케이블
Abstract:
(EN) The present invention relates to a power cable, and particularly, to an ultra-high voltage underground or submarine cable for long-distance direct current transmission. Specifically, the present invention relates to a power cable having an insulation layer having a high dielectric strength in itself, and enabling the effective mitigation of an electric field applied to the insulation layer, and particularly, inhibiting the generation, in the insulation layer, etc., of a de-oiled void that does not contain insulating oil, thereby effectively inhibiting partial discharge, a dielectric breakdown, etc. caused by an electric field concentrated at the void, and thus enabling the lifespan of the power cable to be prolonged.
(FR) La présente invention concerne un câble d'alimentation et plus particulièrement, un câble sous-marin ou souterrain ultra-haute tension destiné à la transmission de courant longue distance. Plus précisément, la présente invention concerne un câble d'alimentation pourvu d'une couche d'isolation présentant en elle-même une résistance diélectrique élevée, qui permet une atténuation efficace d'un champ électrique appliqué à la couche d'isolation, et plus particulièrement, qui empêche la production, dans la couche d'isolation, etc., d'un vide déshuilé qui ne contient pas d'huile isolante, empêchant ainsi efficacement une décharge partielle, une rupture diélectrique, etc. engendrées par un champ électrique concentré au niveau du vide, et permettant ainsi de prolonger la durée de vie du câble d'alimentation.
(KO) 본 발명은 전력 케이블, 특히 장거리 직류송전용 초고압 지중 또는 해저 케이블에 관한 것이다. 구체적으로, 본 발명은 절연층의 자체적인 절연내력이 높고, 상기 절연층에 인가되는 전계가 효과적으로 완화되며, 특히 절연층 등에 절연유가 존재하지 않은 탈유 공극(void)이 발생하는 것을 억제하여 상기 공극에 집중된 전계에 의한 부분방전, 절연파괴 등을 효과적으로 억제함으로써 수명이 연장될 수 있는 전력 케이블에 관한 것이다.
