The present invention relates to a power cable. The power cable according to the present invention includes a flat conductor, an internal semiconducting layer which surrounds the flat conductor, an insulation layer which surrounds the internal semiconducting layer, an external semiconducting layer which surrounds the insulation layer, a metal sheath which is formed on the outer side of the external semiconducting layer, and a cable protection layer which is formed on the outer side of the metal sheath. The flat conductor includes a plurality of flat wire layers in which flat wires are stranded. The purpose of the present invention is to provide the power cable capable of preventing the insulation layer from being twisted by controlling the sum of reaction torque according to the stranded direction of each layer of the flat wire layers. |
