SF6 Gas Servicing Equipment – ENERVAC INTERNATIONAL ULC Hexafluoride (SF6) is an excellent gaseous dielectric for high voltage power applications. It has been used extensively in high voltage circuit breakers and other switchgear employed by the power industry. Applications for SF6 include gas insulated transmission lines and gas insulated power distribution substations.
Effect of micro-H 2 O and micro-O 2 on the decomposition ...· In recent years, heptafluoroisobutyronitrile (C3F7CN) has been proved to be a potential eco-friendly insulating medium to replace sulfur hexafluoride (SF6, the strong greenhouse gas). In this paper, the effect of micro-H2O and micro-O2 on the decomposition of C3F7CN was investigated based on the reactive force field molecular dynamics (ReaxFF-MD) and transition state theory (TST).
