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 remove over 80 percent of 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.
