SF6-alternative gases for application in gas-insulated ...· However, the boiling points of CF 3 I (–22.5 °C at 0.1 MPa) and c-C 4 F 8 (−6 °C at 0.1 MPa) are much higher than that of SF 6, and this limits the application of pure CF 3 I or c-C 4 F 8 in high-voltage apparatus [5, 96]. A possible way to overcome these problems is using a mixture with a gas that has a lower boiling point.
