As the name implies, high-voltage and low-voltage switchgear is the equipment connected with high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, and then go to the low-voltage cabinet through transformer voltage reduction. The low-voltage cabinet then goes to each power distribution box, which is nothing more than electrical equipment assembled with protective devices such as switches and circuit breakers. Distribution cabinet installation

The high and low voltage switch cabinet is an electrical equipment. The external line enters the main control switch in the cabinet first, and then enters the sub control switch. Each branch circuit is set according to its needs. Such as instrument, automatic control, motor magnetic switch, various AC contactors, etc. some are also equipped with high-voltage room and low-voltage room switch cabinet, and high-voltage bus, such as power plant, etc. some are also equipped with low cycle load shedding for main equipment.
