Characteristics and uses of steel cored aluminum stranded wire;
Steel cored aluminum stranded wire, also known as aluminum conductor steel reinforced or ACSR, refers to a reinforced conductor consisting of single or multiple layers of aluminum stranded wire twisted around a galvanized steel core wire. Mainly used in the power and transmission line industries.
For high-voltage transmission lines, due to the limited path of the line and the impossibility of installing multiple lines on one path, people have come up with the method of using one path, one set of iron towers, and hanging multiple wires, that is, one line is equivalent to installing multiple lines; For 500KV transmission lines, China mostly adopts the method of hanging four wires, which is called the same tower parallel installation. Advantages of steel cored aluminum stranded wire;
Steel cored aluminum stranded wire has the characteristics of simple structure, easy installation and maintenance, low line cost, large transmission capacity, and is conducive to laying in special geographical conditions such as crossing rivers and valleys. It has good conductivity and sufficient mechanical strength, high tensile strength, and the tower distance can be enlarged. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels.
The models of steel cored aluminum stranded wire are divided into: JL/G1A JL/G1B JL/G2A JL/G2B JL/G3A
Among them, G1A or G1B refers to ordinary strength steel wire.
G2A or G2B refers to high-strength steel wire.
G3A refers to ultra-high strength steel wire.
