A corrosion resistance branch line for an electric pole is provided to manufacture portions of an inner insulated conductor and outer stranded wires with hard-drawn copper wires, while fabricating portions of the outer stranded wires with ACSR(Aluminum Conductors Steel Reinforced) wires, thereby improving conductivity and sufficiently supporting a tensile force. An inner insulated conductor(110) is made of hard-drawn copper wires(121) having excellent conductivity, while outer stranded wires(120) dispose aluminum steel reinforced wires(123) having excellent tensile forces and the hard-drawn copper wires(121) in turns. The aluminum steel reinforced wires(123) are formed with synthetic resin coating layers(125) on an external surface thereof, and cut off chemical reactions and corrosion transitions between members by the synthetic resin coating layers(125). |
