Title
(EN) HIGH-VOLTAGE POWER CABLE
(FR) CÂBLE D'ALIMENTATION HAUTE TENSION
(KO) 고전압 전력 케이블
Abstract
(EN) The present invention relates to a high-voltage power cable. Specifically, the present invention relates to a high-voltage power cable which has excellent dielectric strength including dielectric breakdown voltage and impulse breakdown strength, and even when the temperature of a cable insulator rises as power transmission progresses or a negative impulse or polarity reversal occurs, can implement and maintain dielectric characteristics.
(FR) La présente invention concerne un câble d'alimentation haute tension. Plus particulièrement, la présente invention concerne un câble d'alimentation haute tension qui présente une excellente résistance diélectrique comprenant une tension de claquage diélectrique et une résistance au claquage par impulsion, et même lorsque la température d'un isolant de câble s'élève à mesure que la transmission de puissance progresse ou qu'une impulsion négative ou une inversion de polarité se produit, peut mettre en œuvre et maintenir des caractéristiques diélectriques.
(KO) 본 발명은 고전압 전력 케이블에 관한 것이다. 구체적으로, 본 발명은 절연파괴전압 및 임펄스 파괴강도 등 절연 내력이 우수하고, 특히 송전이 진행되어 케이블 절연체의 온도가 상승할 때나 부극성 임펄스 또는 극성 반전이 이루어진 경우에도 절연 특성이 구현 및 유지될 수 있는 고전압 전력 케이블에 관한 것이다.
