In the power transformation and distribution device, the current sent from the power supply will first be concentrated on the busbar, and then the current will be distributed from the busbar to various lines for users to use. Since the busbar is a conductor that collects and distributes current, it plays an important role in power transformation and distribution devices. The busbar is also called the busbar. It is divided into three types according to material properties: copper, aluminum, and steel. However, considering the conductivity, resource reserves, price, etc., it is more reasonable to use aluminum as the busbar material. Steel is mostly used for grounding and zero busbars. ...
