Sulfur Hexafluoride, SF6, is an excellent dielectric with unique arc interruption properties that have led to its successful and widespread use in circuit breakers as well as in gas insulated substations. Under ideal circumstances, when a discharge occurs, each fluorine on the SF6 may capture an electron and dissociate from the sulfur.SF6 Gas Analyzer - Huazheng Electric Manufacturing ...

Sulfur dioxide. Sulfur dioxide (SO 2) is a colorless gas with a strong smell.It gets into the air when fuel that contains sulfur is burned.
