Such as instruments, automatic control, motor magnetic switches, all kinds of AC contactor, and some also set high voltage room and low voltage room switchgear, with high voltage bus, such as power plants, and some also have to protect the main equipment of the low week Loaded.


The main function of the switchgear is to open and close, control and protect the electrical equipment in the process of power generation, transmission, distribution and power conversion. Components in the switchgear are mainly circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices.

Or according to the structure of cabinet, it can be divided into open type switchgear, metal enclosed switchgear, and metal Closed armored switchgear; according to the different voltage levels can be divided into high voltage switchgear, medium voltage switchgear and low voltage switchgear. Mainly used in power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textile, factories and mines and residential quarters, high-rise buildings and other different occasions.
