ABB has been developing and deploying alternatives to the greenhouse gas sulfur hexafluoride (SF6) on the path towards greater eco-efficiency and lower environmental impact. Since more than five years ABB offers medium-voltage gas insulated switchgear (GIS) with AirPlus™, a groundbreaking eco-efficient gas mixture with 99.99% lower global warming potential (GWP).

The application of N 2 /SF 6 gas mixtures with SF 6 -contents between 10 % and 20 % reduces the costs for the insulating gas remarkably. This is of great importance when GIL is to be used for long distance bulk power transmission. By this, also the acceptance for long distance applications of this technique is improved on the user side.
