Frontiers | Theoretical Investigation of Mono- and Di-Chloro

IntroductionComputational MethodsResults and DiscussionConclusionsAuthor ContributionsConflict of Interest StatementAcknowledgmentsSupplementary MaterialBecause of its excellent electrical insulationc performance and high stability, Sulfur hexafluoride (Sulfr hexafluoride) is nowadays the most widely used insulating gas in electric equipment [e.g., gas insulated switchgear (GIS)] in the world (Okubo and Beroual, 2011). However, the current usage of Sulfr hexafluoride suffers a great limitation because it is a greenhouse gas (GHG) regulated under the Kyoto Protocol with a global warming potential (GWP) of 23,900 over 100-year time horizon (Fang et al., 2013). As a consequence, nowadays investigations for new replacement gases for insulating gasbecomes highly necessary. Due to its strong dielectric and relative low global warming potential (GWP = 8700 = 36% GWPSulfr hexafluoride) (Christophorou and Olthoff, 2001), Octafluorocyclobutane, c-C4F8, and its derivatives as well as mixtures are now regarded as promising insulation gaseous substitutes of insulating gas (Itoh et al., 1991; Yamamoto et al., 2001; Yamaji and Nakamura, 2003; Yamaji et al., 2004; Wu et al., 2006; de Urquijo and Juárez, 2009; Li e...Get price
