The present invention relates to a power cable, particularly, an ultra-high voltage underground or submarine cable for long-distance direct current transmission. Specifically, the present invention relates to a power cable in which an insulating layer has a high dielectric strength, and an electric field applied to the insulating layer is uniformly and effectively relieved and, particularly, the power cable is structurally stable, has an excellent bending property, and suppresses partial discharge, dielectric breakdown, and the like of the insulating layer, thereby enabling the lifespan to be extended and, simultaneously, productivity to be improved.
