High Voltage GIS Gas Insulated Switchgear (72.5kV / 110kV / 145kV / 220kV / 252kV)
Our GIS Gas Insulated Switchgear is a compact, fully enclosed high-voltage switchgear system using SF6 gas as the insulating and arc-quenching medium. It is designed for reliable operation in urban substations, industrial plants, power utilities, renewable energy projects, and harsh environments where space saving and high safety are required.
The system integrates circuit breaker, disconnector, earthing switch, busbar, and instrument transformers into a sealed metal enclosure, ensuring high reliability, long service life, and minimal maintenance.
