Steel-cored aluminum stranded wire is made by twisting aluminum wire steel wire, is suitable for overhead transmission lines.

It is a steel "core" inside, an aluminum wire is wrapped around the steel core by a twisting method on the outside; the steel core mainly plays the role of increasing the strength, the aluminum stranded wire mainly plays the role of transmitting electric energy;

For high-voltage transmission lines with steel core aluminum stranded wires, Guangxi cable manufacturers reminded that due to the limited path of the line, it is impossible to set up multiple lines on one path, people have come up with a path, a set of iron towers, hanging multiple wires That is, a line is equivalent to the method of setting up multiple lines; for 500KV transmission lines, most of our countries use the method of hanging four wires, which is called paralleling the same tower.

The steel core aluminum stranded wire has the advantages of simple structure, convenient erection maintenance, low line cost, large transmission capacity, is conducive to the laying of special geographical conditions such as crossing rivers valleys. It has good electrical conductivity, sufficient mechanical strength, high tensile strength. , Tower distance can be enlarged so on. Therefore, it is widely used in overhead transmission distribution lines of various voltage levels.
