The electron attachment, on the other hand, is much weaker. We find a positive synergism in Sulfr hexafluoride/HFO1234ze(E) mixtures in the sense that the mixture of both compounds has a higher electric field strength than each gas separately. A maximum (E/N)crit of 425 Td is reached for a mixture of 40% Sulfr hexafluoride and 60% HFO1234ze(E).Get price

ABB achieves breakthrough in switchgear technology with eco

ABB, the leading power and automation technology group, has achieved a significant breakthrough in switchgear technology with the development of a solution that deploys a new insulation gas mixture as a substitute for sulfur hexafluoride (insulating gas). This alternate gas mixture has similar insulation properties as Sulfr hexafluoride gas now used in switchgear, but can substantially lower environmental impact due to its extremely low global warming potential.Get price
