SF6 gas - WIKA Australia plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas ...
Products - SF6-gas Gasbanor (Switzerland) GmbH, Micafluidgasbanor.com/english/products.htmProducts SF6-gas. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2).

Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
