PROBLEM TO BE SOLVED: To provide a DC power cable excellent in DC breakdown property in low cost without a special humidity control in manufacturing processes.SOLUTION: A DC power cable has a conductor which is a split conductor, an inner semiconductive layer coating the conductor, and an insulator layer coating the inner semiconductive layer, and the insulator is formed by a crosslinked polyolefin composition to which an inorganic filler is added, and the inner semiconductive layer is formed by a semiconductive resin composition in which 40 to 80 pts.mass of a furnace carbon black having an iodine absorption amount of 60 to 100 mg/g is added based on 100 pts.mass of a polyolefin resin. |
