Secondary Gas Insulated Switchgear
What is secondary gas-insulated switchgear (GIS)?
Secondary GIS are key components of medium voltage substations designed for MV applications from 12 kV to 40.5 kV. They use gas as the insulation medium between live components in a sealed-for-life design.
What are benefits of secondary GIS?
- Compact design and modular structure save space and suit diverse environments.
- Robust and reliable performance.
- Reduced maintenance needs.
- Enhanced safety with internal arc protection and monitoring systems to help protect equipment and operators
Secondary GIS is used in urban distribution networks, industrial sites, renewables, critical infrastructure, data centers, airports, and public transport systems.
What are Ring Main Units (RMUs)?
RMUs are secondary GIS at load connection points in ring-type distribution networks. Our IoT-connected RMUs offer simple solutions with added benefits.
