GIS Technical Presentation | Electrical Substation ... Gas is a colorless, odourless, non-toxic, non-flammable synthetic gas. SF6 Gas is around 5 times heavier than air and is among one of the heaviest known gases. Under normal conditions SF6 gas is chemically inert & stable; its reactivity is among the lowest of all substances. The excellent insulating properties of SF6 are resulting from to the strong electron affinity (electro-negativity ...4.5/5(7)
SF6 gas - WIKA 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 ...
