“…13,14 Similarly, C 4 F 7 N has to be mixed with CO 2 due to its high boiling point, which limits its insulation and arc-extinguishing performance. 15 Thiazyl triuoride (NSF 3 ) is commonly known as a chemically stable, colorless gas that is used as an important precursor for the preparation of various sulfur-nitrogen-uorine compounds. Recently, the results of a quantum chemical calculation based on a structure-activity relationship model show that NSF 3 is most likely to be an insulating gas with a low greenhouse effect.…”

The usage and emission of SF 6 has been regulated because of high Global Warming Potential (GWP) and long atmospheric lifetime as an insulator in high voltage power transmission equipment. This paper proposes cC 4 F 8 O and its mixtures as a substitute for SF 6 with low GWP and superior insulation performance. cC 4 F 8 O is synthesized by 1,4-diiodoperfluorobutane and fuming sulfuric acid with the yield of 55.7% under optimal conditions. The GWP of cC 4 F 8 O is about one-third that of SF 6 and its dielectric strength is about 1.2-1.4 times that of SF 6. CO 2 and N 2 are mixed with cC 4 F 8 O to lower liquefaction temperature and GWP. The investigation of breakdown voltage and self-recoverability of gas mixtures has shown that the insulation performance and stability of cC 4 F 8 ON 2 is better than cC 4 F 8 O-CO 2 mixtures. The decomposition process of cC 4 F 8 O might produce some nonflammable or inexplosive by-products, such as C 2 F 4 , cC 2 F 4 O, cC 3 F 6 and CF 2 O simulated by Gaussian 09. The results indicate that cC 4 F 8 O and N 2 mixtures have potential to replace SF 6 in electrical equipment.
