High-voltage distribution cabinets refer to electrical products used in power systems for generation, transmission, distribution, energy conversion, and consumption, serving functions such as switching, control, or protection. These products operate at voltage levels ranging from 3.6kV to 550kV and primarily include high-voltage circuit breakers, high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosers and sectionizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgears. The high-voltage switchgear industry is a crucial part of the power transmission equipment manufacturing sector, holding a very significant position in the entire power industry.
