The steel cored aluminum stranded wire is made from aluminum wire and steel wire twisted and become, is suitable for overhead transmission lines.
1. Aluminium conductor steel reinforced structure:
Its internal is steel "core", the outside is twisted with aluminum wire by winding around the steel core; steel core mainly from the role of increasing strength, the aluminium strand mainly plays the role of transmission of electric energy;
2. Aluminium conductor steel reinforced relevant models:
The ACSR model is divided into: JL / G1A JL / G1B JL / G2A JL / G2B JL / G3A
G1A or G1B refers to the ordinary strength of the steel wire.
G2A or G2B refers to high strength steel wire.
G3A refers to the extra-high strength steel wire.
3. The main application of aluminium conductor steel reinforced structure:
For the high-voltage transmission lines, because the route path is limited, and can not be in a path on a number of lines, people come up with a path, a set of towers, hanging a number of wires, that is, a line equivalent to a number of Line of the method; for the 500KV transmission lines,our country mostly adopt the way of hanging four wires, this way of wiring is called the same tower and frame.
