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

Nov 01, 2018 · Russia Troitsk Institute of Innovation and Integration studied and suggested that I 2 is produced primarily by electron collision and dissociation of CF 3 I (Kochetov et al., 2009). C 2 F 6 can be produced with high voltage and severe discharge. As an electronegative gas, C 2 F 6 has superior insulating properties. However, iodine precipitation may lead to a decline of dielectric strength.Get price
