ELK-3, 420 kV with EconiQ busducts showcase Hitachi ABB Power Grids’ 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. This step removes the SF6 in approximately 50 percent of the GIS modules.
ELK-3, 420 kV with EconiQ busducts 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, a small footprint and easy operation, the product allows multiple layouts and incremental substitution of the insulation gas with an eco-efficient solution.
The EconiQ busducts 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 ABB Power Grids’ eco-efficient portfolio for sustainability where products, services and solutions are proven to deliver exceptional environmental performance.
