Steel-cored aluminum stranded wire is made up of aluminum wire and steel wire, which is suitable for overhead transmission lines.
It is internal steel core, external aluminum wire is wound around the steel core by means of stranding; The steel core mainly plays the role of increasing strength, and the aluminum stranded wire mainly plays the role of transmitting electricity.
Steel reinforced aluminium conductor LGJ, has simple structure, convenient erection and maintenance, line low cost, large transmission capacity, and across the rivers and the valley of laying and other special geographical conditions, has good conductivity and enough mechanical strength, tensile strength, pole distance can be amplified, etc. Therefore, it is widely used in aerial transmission and distribution lines of various voltage levels.
