insulating gas gas - WIKA Romania

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.Get price

sf 6 Gas Detection For HV GIS Switchgear - Crowcon F-Gas Detector
