Aug 23, 2020Gas insulated substations (GIS) primarily use sulphur hexafluoride gas as the primary insulator. SF6 is non-toxic, maintains atomic and molecular properties even at high voltages, high cooling properties, and superior arc quenching properties. In addition, is safe.Gas Insulated Substations - Conference 2018 in Washington DC

Switch-disconnectors are nowadays used only in MV installations, most commonly in MV switchgears and in MV overhead lines (see Figure 1) and they have usually an arcing chamber (air or SF6 insulated) to extinguish the arc, but they also perform that extinction in the air (Air Break Switch – ABS).[PDF]Medium-voltage product offer - Schneider Electric

SF6 is widely used as an insulating and arc quenching gas in medium and high voltage transformers. As equipment ages, it is being repaired or replaced with more efficient equipment which typically uses 1/3 the quantity of SF6. This creates a need to recover the SF6 for recycling or disposal.[DOC]REQUEST FOR PROPOSAL
