SF6-alternative gases equipment system

Jun 26, 2018GE's g³ - green gas for grid - is an environmentally friendly alternative to SF6 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 with a drastically reduced environmental impact - g³'s impact is a whopping 98% to 99% less than SF6.
