XGN-12 Gas-Insulated Ring Main Unit – Compact & Safe Solution for 12kV Distribution
⚡ Compact Design Meets High Safety – Ideal for Urban & Renewable Power Grids
The XGN-12 Gas-Insulated Ring Main Unit (RMU) is a 12kV fully sealed switchgear system using SF6 gas insulation for superior dielectric performance and safety. It’s engineered for applications where space, reliability, and operational safety are top priorities, such as urban substations, wind farms, and industrial plants.
With a modular design, it allows various configurations—load break switch (LBS), circuit breaker (VCB), and fuse-switch combinations—making it adaptable for different grid layouts.
