SF6 Decomposition in Gas-Insulated Equipment | Electric …

ABSTRACT The increasing appliion of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas-insulated equipment. In the presence- of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.

RTOC Assessment Report 2014

Some mixtures have been assigned R-nuers, such as R-444B, R-446A and R-447A, whilst most are still under development. These mixtures tend to have operating pressures and capacities similar to HCFC-22 or R-410A, with GWPs ranging from 150 to around 1000 and flammability class 1 (for higher GWPs) and class 2L (medium GWPs).
