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 insulating and switching gas represents the culmination of a decade of research and development by its teams in France, Germany and Switzerland. The g3 gas mixture is based on carbon dioxide, oxygen, and 3M™ Novec™ 4710 Dielectric Fluid from the 3M fluoronitrile family. Fluoronitrile was identified by R&D experts as the most suitable additive to CO2 and O2 to reach the targeted environmental benefit of an alternative to SF6, without compromising the equipment's technical performance and footprint. As a result, the global warming potential (GWP) of GE's g3 gas is 99% lower as compared to SF6.
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.
