ELK-04, 145 kV, EconiQ is the most robust SF6-free gas-insulated switchgear (GIS). It combines a low carbon footprint, superior reliability and low lifecycle costs in a flexible product layout.
It is sustainable and eco-efficient product proven to significantly reduce the CO2 equivalent (CO2 eq) emissions during the complete lifecycle of the product, compared to the SF6 solution.
Based on the well-known modular design of ELK-04 with the largest installed base of any sub-transmission GIS worldwide. It offers easy operation at high-performance ratings and broad flexibility for optimizing substation layouts.
ELK-04, 145 kV, EconiQ is using a 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.
