The HXGN15-12 box-type fixed AC metal-enclosed ring network switchgear (referred to as "ring main unit") is a new type of switchgear designed to meet the needs of urban power grid renovation and construction. In the power supply system, it is also used for breaking load current and short-circuit current, as well as closing short-circuit current. It is suitable for AC 3-10kV, 50Hz distribution systems. Widely used in urban power grid construction and renovation projects, industrial and mining enterprises, high-rise buildings, and public facilities, it serves as a ring network power supply unit and terminal equipment, functioning as a spring-operated mechanism for electrical energy. This mechanism can be operated either manually or electrically. The grounding switch and isolating switch are equipped with manual operating mechanisms. This ring main unit features strong completeness, small size, no combustion, and reliable "five-prevention" functions.
