XGN15-12 High Voltage AC Metal-Enclosed Ring Main Switchgear: Incoming &

The XGN15-12 SF₆ Insulated Ring Main Switchgear (RMU) is a compact 12kV medium-voltage switchgear designed for safe, reliable, and efficient power distribution in utility, industrial, commercial, and renewable energy applications.

As a fully metal-enclosed switchgear, the XGN15-12 uses an SF₆ insulated load break switch (LBS) as the core switching device and can be equipped with vacuum circuit breakers (VCBs), fuse switch combinations, transformer protection units, metering modules, and intelligent monitoring systems according to project requirements.

Designed for modern distribution networks, the XGN15-12 provides high operational reliability, excellent insulation performance, flexible configurations, and low maintenance requirements. It is widely used in ring network, radial network, and terminal power distribution systems.

The XGN15-12 is engineered to improve the safety, efficiency, and reliability of medium-voltage power distribution.

The sealed SF₆ insulation system provides excellent dielectric performance and stable switching capability, ensuring dependable operation even in demanding environments.

Its modular metal-enclosed construction minimizes installation space, making it suitable for compact substations, commercial buildings, and urban distribution networks.

Available configurations include:

• Load Break Switch (LBS)
• Vacuum Circuit Breaker (VCB)
• Fuse Switch Combination
• Incoming & Outgoing Feeder Units
• Transformer Protection Panels
• Metering & Automation Modules

The modular design allows customized solutions for utility companies, EPC contractors, and industrial power projects.

Complete mechanical and electrical interlocking systems help prevent incorrect switching operations while protecting operators and electrical equipment.

The sealed switching chamber reduces routine maintenance requirements and supports long-term stable operation, lowering the total cost of ownership.
