AC Metal Ring Main Unit Switchgear 12kV

The switchgear is a new-generation medium-voltage distribution device specially designed for urban power grid transformation and construction projects. It is widely used for receiving and distributing electric power in ring network systems, while also performing load current switching, short-circuit current interruption, and short-circuit closing operations. The equipment adopts a compact metal enclosed structure and features strong integration, small footprint, and safety and reliability (no risk of combustion or explosion).

Designed for dependable operation and convenient control, the ring main unit adopts a spring operating mechanism and can be operated either manually or electrically according to application requirements. The grounding switch and disconnector are equipped with manual operating mechanisms to ensure operational safety and maintenance convenience. In addition, the unit provides a reliable “five-prevention” interlocking function, enhancing system security and preventing misoperation. 

It is an ideal solution for substations, industrial facilities, commercial buildings, and municipal distribution systems requiring safe, compact, and efficient medium-voltage power control.
