Function and Type of Busbar

1. The role of the busbar
The function of a busbar is to collect, distribute and transmit electrical energy. As the busbar is in operation, there is a huge electric energy through, short circuit, under great heat and electric power effect.

2. Types of busbar
According to the structure of the busbar is divided into hard bus and soft bus, hard bus is divided into rectangle busbar and tube busbar. Rectangular busbar is generally used in the main transformer to the distribution room, its advantages are convenient construction and installation, small changes in operation, large load, but high cost.
Soft busbar is used for outdoor, because of the large space, the wire will not swing to cause insufficient distance between the lines. The construction of soft busbar is simple and the cost is low. In the design of substation, for the bus bar above 35kV, there are aluminum alloy made of tubular busbar.
This kind of busbar structure can reduce the distance between busbars. The knot is clear and the maintenance is small, but the busbar fixing equipment is more complicated.
