Aluminium tubular busbar specifications for Φ40 - Φ400, the latest research and development of electricity use Φ250 aluminium tubular busbar and 13 meters maximum length, Φ300can reach 10 meters, tensile strength reached more than 220 mpa, far beyond the present domestic production at the levels of industry, reached the advanced world first-class level, due to the adopted many new technology in production, make the electric performance of aluminium tubular busbar has improved significantly.
 
Insulated semi-insulated aluminium tubular busbar is an extension of our company chalco's products and services. It is a good material for connecting 35KV and 110KV household internal and external switch cabinets and transformers. It is not only beautiful, easy to maintain, but also has better electrical conductivity than rectangular aluminium tubular busbar.

The aluminum wire in the middle of the aluminium tubular busbar is called the "damping wire", because the alternating current has the "skin effect", so the damping wire inside the aluminium tubular busbar is only a stable and balanced function.
For example, an empty bottle can drip around on the ground, and put a small amount of water in the bottle, it is not easy to rotate, that is the reason! The aluminum wire in the middle of the aluminium tubular busbar should be placed without steel core. It is placed in the aluminium tubular busbar. It is not connected with the terminal plate, but plays a stabilizing role to prevent the aluminium tubular busbar. from resonating and causing violent vibration.
