Zusammenfassung: | The present invention relates to a power cable (1), which may solve or at least relieve problems of an existing technology. The power cable (1) comprises: power cores (3a, 3b, and 3c) that includes a conductor (5), an insulation system which includes an inner semi-conductive layer (9) arranged around the conductor (5), an insulation layer (11) arranged around the inner semi-conductive layer (9), and an outer semi-conductive layer (13) arranged around the insulation layer (11), a first metal waterproof layer (15) which is arranged around the outer semi-conductive layer (13) concentrically to the outer semi-conductive layer (13), a semi-conductive polymer layer (19) which is arranged around the first metal waterproof layer (15) concentrically to the first metal waterproof layer (15), and a second metal waterproof layer (21) which is arranged around the semi-conductive polymer layer (19) concentrically to the semi-conductive polymer layer (19); and an outer sheath (25) that is arranged around the second metal waterproof layer (21).
전력 케이블 (1) 은 전력 코어 (3a) 로서, 도체 (5), 도체 (5) 의 주위에 배열된 내부 반도전층 (9), 내부 반도전층 (9) 의 주위에 배열된 절연층 (11), 및 절연층 (11) 의 주위에 배열된 외부 반도전층 (13) 을 포함하는 절연 시스템, 외부 반도전층 (13) 과 동심으로 외부 반도전층 (13) 의 주위에 배열된 제 1 금속 방수층 (15), 제 1 금속 방수층 (15) 과 동심으로 제 1 금속 방수층 (15) 의 주위에 배열된 반도전 폴리머 층 (19), 및 반도전 폴리머 층 (19) 과 동심으로 반도전 폴리머 층 (19) 의 주위에 배열된 제 2 금속 방수층 (21) 을 포함하는, 상기 전력 코어 (3a, 3b, 3c); 및 제 2 금속 방수층 (21) 의 주위에 배열된 외부 피복 (25) 을 포함한다. |
