The CYRM-12 Gas-Insulated Ring Main Unit (RMU) Switchgear is a 12kV metal-enclosed distribution system designed by Conya Electric. It uses SF₆ gas insulation within a sealed stainless-steel tank to ensure reliable performance, compact size, and zero maintenance.
Each unit can be configured with modular components—including load switch modules, load switch-fuse combinations, vacuum circuit breaker units, and busbar incoming modules—allowing flexible system design for different applications.
Built with advanced materials and insulation technology, the CYRM-12 offers excellent electrical and mechanical strength, minimal environmental influence, and easy installation. Its intuitive and safe operating layout provides clear visibility of switch positions, while the large feeder wiring capacity supports a wide range of medium-voltage power distribution networks.
SF₆ Gas-Insulated Metal-Enclosed Structure: The CYRM-12 series ring main unit switchgear adopts a sealed SF₆ gas-insulated metal-enclosed design in a common box structure. This ensures full insulation, arc-resistance, and reliable protection for medium-voltage power distribution systems.
Modular Configuration Options: The switchgear can be flexibly configured with load-switch units, load-switch-fuse combinations, vacuum circuit-breaker units, and busbar incoming modules, meeting diverse system requirements.
Advanced Materials and Technology: Built with high-quality insulating materials and advanced manufacturing technology, the CYRM-12 provides excellent electrical and mechanical performance with long service life and operational stability.
Reliable in Harsh Environments: Its sealed gas-insulated enclosure prevents moisture and dust intrusion, making the equipment less affected by environmental or climatic conditions, ensuring consistent performance in demanding installations.
Compact, Space-Saving Design: The compact cabinet dimensions reduce installation footprint and simplify on-site integration, making it suitable for urban substations, industrial facilities, and high-rise buildings.
Maintenance-Free and Flexible Operation: The sealed gas system requires no routine maintenance and allows for flexible modular combinations to suit various network topologies.
User-Friendly and Intuitive Layout: The clear, intuitive panel layout supports safe, straightforward operation and visual indication of switch positions. The large feeder wiring capacity makes it adaptable for different wiring configurations and expansion needs.
