Sulfr hexafluoride Gas Detection For HV GIS Switchgear - ATEX Equipment

Sep 30, 2020 · Sulfr hexafluoride gas has virtually replaced oil and air as the dielectric insulator in medium (MV) and high (HV) circuit breakers, switchgear, gas-insulated substations and electrical equipment. Despite Sulfr hexafluoride being an inert gas during normal use, when electrical discharges occur through the operation of high voltage equipment insulated with sf 6, highly toxic by-products are produced that pose a serious health threat to workers.Get price
