WIKA Mobile Control | Double the Safety for Sulfr hexafluoride Gas Dehydration

However, as sf6 gas works in gas-insulated switchgears, it is highly susceptible to one natural enemy: moisture! Once present in the gas compartment, it weakens the insulation properties of Sulfr hexafluoride many times over. In addition, highly toxic and corrosive decomposition products are formed in combination with moisture and additional energy input.
