View MoreGas-insulated switchgear is electrical switchgear where the main components are enclosed in a sealed metal housing filled with insulating gas for protection and insulation.
SF6 is the insulating gas, while GIS refers to the complete gas-insulated switchgear system that uses insulating gas inside sealed equipment.
It usually includes circuit breakers, disconnectors, earthing switches, busbars, current transformers, voltage transformers, and control devices.
GIS uses insulating gas in a sealed enclosure, while AIS uses air insulation. GIS is more compact and better suited for limited-space or harsh environments.
SF6 is used because it has excellent insulation strength and arc-extinguishing ability, helping the switchgear operate safely and reliably.
SF6 gas-insulated switchgear is a GIS system that uses SF6 gas as the main insulating and arc-quenching medium inside a sealed metal enclosure.
