Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switchgear, with high-voltage busbars, such as power plants, etc.

The main function of a switchgear is to open, close, control, and protect electrical equipment in the process of power generation, transmission, distribution, and energy conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. There are many classifications of switchgear. For example, they can be divided into removable switchgear and fixed switchgear through the installation of circuit breakers; or according to the structure of the cabinet, they can be divided into open switchgear, metal-enclosed switchgear, and metal Closed armored switchgear; according to different voltage levels, it can be divided into high-voltage switchgear, medium-voltage switchgear and low-voltage switchgear.
