XGN15-12 AC Metal-enclosed Ring Main Unit Switchgear

Compact Design: Depth 1200mm, height 2200mm, footprint only 0.72㎡, suitable for scenarios with limited switch room space

High Reliability: SF6 gas annual leakage rate <0.1%, mechanical operation without lubrication, maintenance cycle up to 10 years

Flexible Expansion: Standard configuration 2 inlets and 3 outlets, expandable to 4 inlets and 6 outlets, meeting complex network topology requirements

The XGN15-12 AC Metal-enclosed Ring Main Unit Switchgear (commonly called an RMU) is a compact, high-performance device for medium-voltage 12kV power distribution. It’s a core component in ring network power systems—setups that use multiple power sources to ensure continuous supply. Unlike open-type switchgear, the XGN15-12 uses SF6 gas insulation, which provides superior electrical insulation and arc-quenching capabilities while shrinking the unit’s size. Its metal-enclosed design enhances safety by containing electrical components, preventing accidental contact, and reducing the risk of electrical hazards. The XGN15-12 complies with the GB/T 11022 standard, a global benchmark for medium-voltage switchgear, making it a trusted choice for urban power grids where space and reliability are top priorities.

Urban Ring Network Power Supply

In urban power grids, the XGN15-12 is the backbone of ring network power supply systems. These systems use multiple power sources to ensure continuity: if one source fails, the XGN15-12 quickly transfers the load to another source, minimizing outages. Its compact design fits perfectly in urban switch rooms, which are often located in dense areas with limited space.

Residential Community 10kV Distribution

Residential communities need reliable power for hundreds or thousands of households. The XGN15-12’s high reliability and low maintenance needs make it ideal here—its long maintenance cycle reduces service visits, and its metal-enclosed design keeps residents and technicians safe. It also ensures stable power for essential services like lighting, heating, and household appliances.

Commercial Center and Industrial Park Power Systems

Commercial centers (like malls or office towers) and industrial parks have high power demands and require uninterrupted supply to avoid revenue loss or production downtime. The XGN15-12’s flexible expansion capabilities let it adapt to growing power needs, while its SF6 gas insulation ensures stable performance during peak load periods. Its ability to handle short-circuit currents also protects critical equipment from damage.
