Decomposition pathway of C4F7N gas considering the participation of ions
Journal of Applied Physics, 2020Recently, fluoronitrile C4F7N is regarded as a promising alternative gas for SF6, and its global warming potential (GWP) is extremely high. C4F7N has good insulation properties and a relatively low GWP, so it can be used as an insulation medium for gas-insulated switchgears.

Assessment on the toxicity and application risk of C4F7N: A new SF6 alternative gas
Journal of Hazardous Materials, 2019C4F7N (fluorinated nitrile) gas mixture has been utilized as the gas insulating medium to replace the most greenhouse gas SF6 (sulphur hexafluoride). Nowadays, there are few reports on the toxicity mechanism of C4F7N and studies on the application risk of C4F7N is insufficient.
