1. The bus bar is divided into hard bus bar and soft bus bar.
2. According to different shapes, hard busbars can be divided into: rectangular busbars, tubular busbars, trough busbars, diamond busbars, etc.
3. Rectangular busbar is a commonly used busbar. Depending on the material, there are aluminum busbars (aluminum bars) and copper busbars (copper bars). The advantage of rectangular bus is that it is easy to install, the operation changes very little, and the current carrying capacity is large, but the cost is higher.
4. Tubular busbars are usually used in cooperation with knife switches. The current multi-directional steel pipe manifold is convenient for construction, but the current carrying capacity is very small. Although aluminum tubes have a large current-carrying capacity, the construction process is difficult and is rarely used nowadays.
5. Trough and diamond busbars are used for high-current busbridges and power distribution occasions that require high thermal and dynamic stability.
6. Soft busbars are usually used outdoors. The outdoor space is large, the line spacing is wide, the heat dissipation effect is good, the construction is convenient, and the cost is low.
In general, when installing a tubular bus, the device should also be installed according to the application of the surrounding environment. Ensure safety in production and operation.
