XGN15-12 Package High voltage switchgear

The main function of switch cabinet is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and electric energy conversion.  The components in the switch cabinet mainly include circuit breaker, disconnecting switch, load switch, operating mechanism, mutual inductor and various protective devices.  There are many classification methods of switchgear, such as the circuit breaker installation can be divided into moving switchgear and fixed switchgear;  Or according to the different structure of the cabinet, it can be divided into open switch cabinet, metal closed switch cabinet, and metal closed armored switch cabinet;  According to the different voltage levels can be divided into high voltage switchgear, medium voltage switchgear and low voltage switchgear.  Mainly applicable to power plants, substations, petrochemical, metallurgical steel rolling, light industry textile, factories and mining enterprises and residential areas, high-rise buildings and other different occasions.
