High-voltage distribution panels refer to electrical products used in power systems for generation, transmission, distribution, power conversion, and consumption, serving functions such as switching, control, or protection. They operate at voltage levels ranging from 3.6kV to 550kV and mainly include high-voltage circuit breakers, disconnecting and earthing switches, load switches, automatic reclosing and sectioning devices, operating mechanisms, explosion-proof distribution equipment, and switchgear cabinets. The high-voltage switchgear manufacturing industry is a crucial component of the transmission and transformation equipment manufacturing sector, holding a very important position in the entire power industry.
