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 products feature the same ratings and same dimensional footprint as the state-of-the-art SF₆ ones, with a drastically reduced environmental impact: more than 99% less gas global warming potential (GWP), comparatively. g³ products have a significantly improved life cycle assessment (LCA) compared with SF₆ products and other alternatives. In addition, with product dimensions remaining the same, there is no major increase of raw materials, thus no pollution transfer induced on any other environmental indicators. Also, g³ products operate with no restriction under the same temperature range as SF₆ products (down to -30°C).

Like SF₆, g³ is non-toxic and not flammable. It falls in the same safety class as SF₆.
