ACSR is made of twisted aluminum wire and steel wire, suitable for overhead transmission lines.The inside of it is a steel core, and the outside is twisted with aluminum wires around the steel core; the steel core mainly plays the role of increasing the strength, and the aluminum stranded wire mainly plays the role of transmitting electric energy.

Steel-cored aluminum stranded wire, LGJ, has the advantages of simple structure, convenient erection and maintenance, low line cost, large transmission capacity, and is conducive to the laying of special geographical conditions such as across rivers and valleys, and has good electrical conductivity and sufficient mechanical strength. It has the characteristics of high tensile strength and the distance between the tower and pole can be enlarged.Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.
