AIS (Air Insulated Substation) SF₆ Circuit Breaker up to 800 kV is a high-voltage switching device used in air-insulated substations to control, protect, and isolate electrical equipment in transmission networks. It utilizes sulfur hexafluoride (SF₆) gas as the insulating and arc-quenching medium, which provides excellent dielectric strength and high interrupting capability, enabling safe and reliable operation even at ultra-high voltages like 800 kV.
