Provided is a DC power cable including a conductor, an inner semiconductive layer, an insulation and an outer semiconductive layer. In particular, the inner semiconductive layer or the outer semiconductive layer may be formed from a semiconductive composition containing a polypropylene base resin or a low-density polyethylene base resin and carbon nano tubes; and the insulation may be formed from an insulation composition containing a polypropylene base resin or a low-density polyethylene base resin and inorganic nano particles. The resulting power cable may have improved properties such as volume resistivity, hot set, and so on, and excellent space charge reducing effect.
