SF6 SF6 (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF6 SF6 is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO2 and a lifetime of 3,200 years in the atmosphere. With grid operators across the world becoming increasingly concerned about the environmental impact, GE offers a commercially available and viable alternative to SF6 SF6 to help utilities and industries reduce their environmental impact.
INTRODUCING g3 G3 INSULATING AND SWITCHING GAS
g³, G3 (pronounced "g" cubed) is GE's game-changing alternative to SF6 SF6 gas, developed for HV electrical transmission equipment.
g³ G3 products feature the same ratings and same dimensional footprint as the state-of-the-art SF6 SF6 ones, with a drastically reduced environmental impact: more than 99% less gas global warming potential (GWP), comparatively. Also, g³ G3 products operate with no restriction under the same temperature range as SF6 SF6 products (down to -30°C).
Like SF6, g3 is non-toxic and not flammable. It falls in the same safety class as SF6.
g³ insulating and switching gas is a proven alternative to SF6 SF6 that provides technical, environmental and financial advantages.
g³ is a fully type-tested gas mixture that provides the same technical performance as SF6, SF6 while reducing the environmental impact.
