Maintenance sulfur hexafluoride joints

Sulfur hexafluoride in the electrical power industry is primarily used in high-voltage gas-insulated switchgear (GIS), which consumes 80 % of the sf 6 used, with medium-voltage GIS consuming only about 10 % (Niemeyer and Chu, 1992; Dervos and Vassiliou, 2000; Xu et al., 2011; Xiao et al., 2018).
