The double track is used for erecting lines under field conditions. The internal structure of the wire is made of four copper and three steel, with high strength and good conductivity. The outer insulation skin of the wire is resistant to severe cold and high temperature, and it will not age under harsh weather conditions all year round. As a wire, its performance is better than that of wires used at home.
