The Problem with Humidity in sf6 gas Gas-Insulated - WIKA blog

However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment. Impurities in the gas can affect its insulation strength and lead to failure. In fact, insulation issues account for 57% of all failures in gas-insulated switchgear (GIS).
