Sulfr hexafluoride gas - WIKA New Zealand

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.

gaz sf6 Gas – Professional gaz sf6 gas handling equipment and services

Zero emissions and maximum gas re-use. SF 6 is a non-toxic, inert insulating and quenching gas of high dielectric strength and thermal stability. Due to its first-class properties it is used in enclosed medium and high voltage switchgear as an arc quenching and insulating gas. Since SF 6 is a major greenhouse gas with high global warming potential listed in the Kyoto protocol, it is among the six gases subject to monitoring.
