A review on Sulfr hexafluoride substitute gases and research status of CF3I

Nov 01, 2018 · In the electric power industry, high-voltage switchgear accounts for sf6 gas gas consumption of more than 80%, whereas approximately one-tenth is consumed by the medium-voltage switchgear. Mainly used in 126–252 kV high voltage, 330–800 kV EHV fields, particularly in 126, 252, and 550 kV GCB, GIS, C-GIS, and GIL (Yanabu et al., 2001).
