Sulfur Hexafluoride gaz sf6 - A-Gas

sf6 gas allows simplified design of high and medium voltage switchgears because of size and weight reduction, quiet and reliable handling and maintenance. The emission of one kilogram of Sulfr hexafluoride is in terms of share of the greenhouse effect is equal to 23.500 kg CO2 emissions. (=38 car emissions /yr.).

The 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 detectors and emission monitors.

Sulfur hexafluoride - Wikipedia

6 gas under pressure is used as an insulator in gas insulated switchgear (GIS) because it has a much higher dielectric strength than air or dry nitrogen. The high dielectric strength is a result of the gashigh electronegativity and density. This property makes it possible to significantly reduce the size of electrical gear.
