Electric power wire

The utility model discloses an electric power wire, which comprises a steel core, a conductor and an outer insulation protective layer. An inner insulation layer is wrapped outside the steel core, the cross section of the conductor is shamrock-shaped, the conductor is hollow, and the inner insulation layer is sleeved in the conductor. The outer insulation protective layer is wrapped on the outer surface of the shamrock-shaped conductor. The electric power wire has the advantages that the steel core with high tensile strength is arranged in the electric power wire to enable the wire to have high tensile strength, the center of the conductor is hollow, the length of the outer surface is lengthened, contact face is large, resistance is reduced, conductivity is strong, conductive performance is good, the natural law of current collected on skin is satisfied, and the electric power wire is light in weight.
