PROFESSIONAL RING MAIN UNIT (RMU) MANUFACTURER

• The XGN15‑12 12 kV Air-Insulated Ring Main Unit (RMU) is indoor fixed-type AC metal-enclosed switchgear designed for 50 Hz, 11 kV/12 kV ring-main and terminal distribution systems.
• Atmospheric-pressure air is used as the principal insulation medium. The RMU can be configured with a vacuum or SF₆ load-break switch, switch-fuse combination or vacuum circuit-breaker. A completely SF₆-free version is also available.
• Its compact, modular and expandable design provides flexible configuration, reliable interlocking and convenient installation. It is suitable for municipal networks, industrial facilities, commercial buildings, prefabricated substations and infrastructure projects.
• The product is designed in accordance with IEC 62271‑1, IEC 62271‑200, IEC 62271‑102, IEC 62271‑103, IEC 62271‑105 and IEC 60529. Final ratings and configurations are subject to project requirements and applicable type-test reports.

The GoWatron SRM6-12 is a 12kV SF₆ gas-insulated ring main unit, designed as a compact and modular medium-voltage switchgear assembly. All primary high-voltage live components are fully hermetically sealed inside a stainless steel gas tank to achieve full insulation and complete enclosure. The equipment is highly resistant to dust, moisture, condensation, salt fog and small animal intrusion, enabling long-term maintenance-free and stable operation. Supporting free combination and expansion of multiple functional modules, it adapts to diverse power distribution solutions. Widely deployed in municipal power grids, renewable energy stations, industrial and commercial parks and prefabricated substations, the product is manufactured and tested in strict accordance with national and IEC international standards to ensure safe and reliable operation for all projects.
