HXGN-12 AC metal distribution board (ring main unit)
I. Product Overview
HXGN-12 AC with metal enclosed distribution equipment (called ring main unit, RMU) is a new type of high voltage distribution system designed for urban electrical repair and construction applications. It is suitable for interrupting load current, short circuit current and creating short circuit current in power systems.
The distribution equipment is equipped with a vacuum load switch and a spring mechanism supporting both manual and electrical operation modes. The earthing switch and disconnector have manual controls. Featuring complete components, compact dimensions, no risk of fire or explosion, and reliable "five-prevention" functions, it adapts to the safe operation requirements of various power distribution scenarios.
