  • 15 FAQs about SF6 Gas and SF6 Breakers - WIKA blog

    What is SF6 gas? Sulfur hexafluoride is an octahedral (eight faces and six vertices) molecule. It consists of six fluorine atoms surrounding a sulfur atom. What are the characteristics of SF6 gas? SF6 is colorless, odorless, nonflammable, and nontoxic. It is virtually inert, which means it is stable and does not react with other chemicals under normal conditions. Why is SF6 gas such a good dielectric medium? First, dielectricity is the ability to transmit electricity without conductivity, and dielectric strength refers to how well something can withstand high voltage without breaking down. What is the importance of arc quenching in T&D equipment? When switching or opening an electrical circuit that deals with more than 250 volts, as the contacts start to open, an arc forms between them.
