Product Knowledge of Steel Core Aluminum Stranded Wire


Steel Core Aluminum Stranded Wire


The steel-cored aluminum stranded wire is made of stranded aluminum wire and steel wire and is suitable for overhead transmission lines. The inside is a steel "core", the outside is wrapped around the steel core by stranding with aluminum wire; the steel core mainly plays the role of increasing strength, and the aluminum strand mainly plays the role of transmitting electric energy.

Steel-cored aluminum strand wire is the main application variety in the main line of power system in our country. In the future, the steel-cored aluminum strand will still be the main product used in China's power network. This is mainly due to the characteristics of steel-cored aluminum strands and the design characteristics of China's power grid.

Application of steel core aluminum stranded wire:

For the high voltage transmission line, because the path of the transmission line is limited and it is impossible to set up multiple lines in one path, people have come up with a method of adopting one path, a set of iron towers and hanging multiple wires, that is, one line is equivalent to multiple lines. For the transmission lines of 500KV, most of our country uses the way of hanging four wires, which is called the parallel of the same tower.
