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).
Health index and risk assessment models for Gas Insulated ...· The failure rate of Gas Insulated Switchgear (GIS) operating under tropical conditions is about twice the value reported by the third CIGRE's survey in 2007. Three major failure modes that lead to catastrophic failure of a GIS in tropics are the insulation breakdown, the primary joint-conductor failure, and the driving mechanism failure.
