EconiQ GIL ELK-3, 420 kV showcase Hitachi Energy’s commitment to reducing the volume of sulfur hexafluoride (SF6) in transmission GIS voltage ratings. This product introduces an important step towards complete 420 kV eco-efficient switchgear by substituting the insulation gas in the product’s busducts with SF6 -free gas mixture.
EconiQ GIL ELK-3, 420 kV is the ideal solution for a reliable eco-efficient energy supply up to a rated voltage of 420 kV. Based on a few building blocks with standardized dimensions, same footprint as SF6 and easy operation, the product allows multiple layouts and incremental substitution of the insulation gas with an eco-efficient solution.
The EconiQ GIL of ELK-3, 420 kV, are operating with an insulation gas mixture of Fluoronitriles (C4-FN), Carbon dioxide (CO2) and Oxygen (O2). This mixture essentially eliminates the CO2 equivalent emissions of the insulation medium compared to SF6 gas.
EconiQ is Hitachi Energy’s eco-efficient portfolio for sustainability where products, services and solutions are proven to deliver exceptional environmental performance.
