Switchgear technology with eco-efficient insulation gas

New gas mixture offers alternative to SF6 and has potential to reduce carbon footprint of GIS by up to 50 per cent – technology being deployed in a Swiss pilot project
 ABB 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 sulphur hexafluoride (SF6).
This alternate gas mixture has similar insulation properties as SF6 gas now used in switchgear, but can substantially lower environmental impact due to its extremely low global warming potential. ABB’s gas-insulated switchgear (GIS) with the new gas mixture has the potential to lower carbon dioxide equivalent emissions by up to 50 per cent through the lifecycle of the equipment, compared to its predecessor with the same rating.
“This is a significant achievement and can pave the way for more eco-efficient switchgear in the years ahead,” said Bernhard Jucker, Head of ABB’s Power Products division. “It will enable our customers to lower environmental impact and is very much in line with ABB’s ongoing commitment to technology and innovation to enable power and productivity for a better world.”
