SF6 Gas Analysis - Qrometric Insulated Switchgear. For SF6 filled gas compartments, SF6 in accordance with either IEC 60376 or IEC 60480 is used. In order to prevent condensation, the maximum allowable water content is defined by a dew-point no higher than – 5 °C. Gas compartment fill specifications typically define much lower dew points (manufacturer dependent).

Products - SF6-gas Gasbanor (Switzerland) GmbH, Micafluidgasbanor.com/english/products.htmProducts SF6-gas. Sulfur Hexafluoride is a colorless and odorless gas. SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2).
