Aluminum bar

For indoor high-voltage power distribution or high-power low-voltage power distribution room.

The aluminum bar refers to the rectangular and long strip aluminum which is used as the electrical equipment wire. The aluminum bar is mainly used for the high- and low voltage apparatus, switch contact, power distribution equipment, bus duct and other electrical engineering. The aluminum bar is taken as the conductive bus, and has the advantages of low resistivity, large bending degree and so on. Silver-white light metal. It has ductility and extensibility.

1. High electric conductivity, the electric conductivity is up to 56.5-60.

2. Light weight, high strength, the surface has strong corrosion resistance and oxidation resistance.

3. No magnetic property, so as to avoid magnetic hysteresis consumption with other metal.
