Power cable

Abstract

A power cable includes a conductor; an inner semi-conductive layer covering the conductor; an insulating layer covering the inner semi-conductive layer, the insulating layer being impregnated with an insulating oil; an outer semi-conductive layer covering the insulating layer; a metal sheath layer covering the outer semi-conductive layer; and a cable protection layer covering the metal sheath layer. The insulating layer is formed by cross-winding insulating paper and impregnating the insulating paper with the insulating oil. The inner semi-conductive layer and the outer semi-conductive layer are formed by cross-winding semi-conductive paper and impregnating the semi-conductive paper with the insulating oil. A thickness of the outer semi-conductive layer is 7.5 to 15% of a total thickness of the inner semi-conductive layer, the insulating layer, and the outer semi-conductive layer.
