Sulfr hexafluoride Gas Hazards and How to Avoid Them - WIKA blog

Sulfur hexafluoride, a highly effective insulator and arc quencher, is commonly found in the power transmission and distribution industry. But to protect equipment, personnel, and the environment, users must be aware of the common sf 6 gas hazards and how to avoid them. Sulfur hexafluoride (SF 6), when sealed inside power transmission and distribution (TD) equipment, insulates switchgears, circuit breakers, and disconnectors by quenching dangerous arcs.
