g³ is an alternative to SF₆ for electrical switchgear, developed and patented by GE Vernova. It is a mixture of CO₂, O₂ and an additive, C₄F₇N, produced by Climalife under GE Vernova’s specifications. The g³ gas mixture reduces the impact of the gas on global warming by 99% compared with SF₆ resulting in a significant reduction of greenhouse gas emissions. This new insulating and switching solution is suitable for the development of a new generation of high- and ultra-high voltage metal-enclosed switchgear. Equipment using g³ maintains the same dimensions and performance as those working with SF₆.

The g³ gas mixture is available in four versions. Follow the recommendations of the equipment manufacturer to select the correct one:

• g³-C4-FN-40-00
• g³-C4-FN-60-05
• g³-C4-FN-35-13
• g³-C4-FN-50-13
