Zunyi City Steel Core Aluminum Stranded Wire Manufacturer Guizhou Special Steel Core Aluminum Stranded Wire

Description :

　　1. Related structures

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

　　It has a steel "core" inside and is wrapped around the steel core with aluminum wire twisted together on the outside; Steel core mainly serves to increase strength, while aluminum stranded wire mainly serves to transmit electrical energy;

　　2、 Related models

　　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.

　　Model difference: Taking JL/G1A-240/30 steel core aluminum stranded wire as an example.

　　In the national standard (GB/T1179-2008), it is represented by the current JL/G1A-240/30;

　　In the national standard (GB/T1179-1983), it is represented by LGJ-240/30.

　　3、 Main applications

　　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.

　　4、 Related advantages

　　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.
