Abstract

Mixtures of SF6 with nitrogen or perfluoromethane are needed for equipments to operate correctly at temperature as low as −50°C. Improvement of experimental setups and analytical techniques have permit the detection and identification of new gaseous byproducts formed when these mixtures are exposed to electrical discharges. Formation of NF3, N2F2 and some perfluoromethylsulfanes has been revealed in addition to other heavy compounds containing the SF5° radical. The paper also presents results obtained with SF6-air (dry and wet) mixtures.
