Zusammenfassung: | The present invention relates to a power cable; specifically, relates to an ultra-high voltage underground or submarine cable. More specifically, the self dielectric strength of an insulating layer is high; an electric field applied to the insulating layer is effectively buffered; and the deterioration of the insulating layer is able to be prevented in the connection process of a cable. As such, a lifespan is extended; and at the same time, a thickness of the insulating layer is minimized to reduce an outer diameter of the cable, thereby being able to improve flexibility, pulling, and workability of the cable.
본 발명은 전력 케이블, 특히 초고압 지중 또는 해저 케이블에 관한 것이다. 구체적으로, 본 발명은 절연층의 자체적인 절연내력이 높고, 상기 절연층에 인가되는 전계가 효과적으로 완충되며, 케이블의 접속 공정시 절연층의 열화를 방지할 수 있어, 수명이 연장되는 동시에, 절연층의 두께를 최소화하여 케이블의 외경을 감소시킬 수 있기 때문에 케이블의 유연성, 포설성, 작업성 등이 향상될 수 있는, 전력 케이블에 관한 것이다. |
