g³ - Green Gas for Grid
SF6 alternative for high voltage applications above 66 kV
g³ - green gas for grid - is GE‘s replacement for SF6 gas developed in collaboration with 3M. g³ is a proven and ready-to-go alternative insulating gas mixture for high voltage (HV) electrical transmission equipment, which provides the same technical performance as SF6 in an environmentally friendly way – the impact of g³ is a whopping 98% to 99% less than SF6 gas.
The g³ gas offers an efficient combination of low global warming potential (GWP) with high dielectric performance and extended operating temperatures in accordance with the typical Transmission System Operators’ (TSO) needs.
Sulfur-hexafluoride (SF6) is used in the HV electrical transmission industry because it is an excellent gaseous dielectric medium. Unfortunately, it is also the greenhouse gas with the largest global warming potential (23,500 times more than C02). Much effort has been made across the industry in the last decades to find a viable alternative gas. With g³, a replacement is found in fluoronitrile versus sf6.
g³ is an environmentally friendly alternative to SF6 that provides a number of technical, environmental and financial advantages.TECHNICAL
