GE and Hitachi ABB Agree to Innovation to Lower Greenhouse

Apr 21, 2021 · The two technological giants have signed a landmark agreement to use a new and pollution-reducing gas in high-voltage transmission equipment. Normally transmission equipment uses Sulfur Hexafluoride (sf6 gas) for insulating and switching. Unfortunately it is a powerful greenhouse gas. Until now there have been no practical alternatives due to the specific properties of sf6 gas gas.
