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, effectively inhibiting a local potential difference at the edgewise direction in the insulation layer, and a surface flashover in the length direction of the cable caused thereby, 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 à ultra-haute tension destiné à la transmission longue distance de courant continu. Plus précisément, la présente invention concerne un câble d'alimentation pourvu d'une couche d'isolation présentant en elle-même une résistance diélectrique élevée, et permettant une atténuation efficace d'un champ électrique appliqué à la couche d'isolation, et plus particulièrement, une inhibition efficace d'une différence potentielle locale au niveau de la direction latérale dans la couche d'isolation, ainsi qu'un contournement de surface dans la direction longitudinale du câble ainsi provoqué, ce qui permet 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 내의 연층 방향에서의 국부적인 전위차 및 이에 의한 케이블 길이 방향의 연면 파괴를 효과적으로 억제함으로써 수명이 연장될 수 있는 전력 케이블에 관한 것이다.
