Product Description
MGS Series 12-36kV SF6 Insulated RMU Switchgear 630A 20kA
12kV | 13.8KV | 24KV | 33KV | 36KV High Voltage Cabinet Panels
The MGS Series Ring Main Unit is an extensible, SF6 insulated switchgear solution designed for medium voltage distribution networks. Available in 10 configurations to suit various switching applications in 12/24/36 kV systems, it provides a complete solution for secondary distribution networks with identical user interfaces to ABB equipment.
Key Features
- All high voltage live parts contained in a 3mm stainless steel, air-tight SF6 gas tank
- Complete SF6 insulation ensures exceptional reliability and maintenance-free operation
- Available with either switch-fuse combination or circuit-breaker with relay for transformer protection
- Optional integrated remote control and monitoring unit
- IP67 protection for gas tank and fuse holder, IP4X for RMU enclosure
- Successfully tested for internal arc (20kA for 1s) and water treatment (11kV for 24 hours)
Service Environment
- Temperature range: -20℃ to +40℃
- Humidity: 90% daily average, 95% monthly average
- Maximum installation altitude: 2500m
- For non-polluted environments free from corrosive/flammable gases
- Not suitable for areas with frequent violent shaking
Typical Applications
- Compact secondary substations
- Small industrial facilities
- Wind power plants
- Commercial buildings (hotels, shopping centers, offices)
- Special installations (airports, hospitals, tunnels, underground railways)
- Light mining applications
