The HXGN15-12(SF6) series fixed AC metal-enclosed ring main unit (RMU) is developed by integrating advanced international technologies, specifically designed for rural and urban power grid renovation and construction in China. It adopts an SF6 gas-insulated three-position switch as the main isolation unit, with a compact air-insulated busbar system. By incorporating sensor technology and state-of-the-art protective relays, along with flexible assembly solutions, it fully adapts to evolving market demands. Suitable for 50Hz AC power systems up to 24kV, it is used for power reception and distribution. The cabinet is riveted after CNC machining, achieving IP3X protection level, and features reliable mechanical interlocking and anti-misoperation mechanisms. Key advantages include compact size, lightweight design, long lifespan, low maintenance, cost-effectiveness, aesthetic appearance, and user-friendly operation. The HXGN15-12(SF6) complies with IEC60420, GB3906, and DL/T404-916 standards.
