EconiQ™ high-voltage portfolio: Game-changing technology for the environment
Hitachi Energy is fostering collaboration with customers and partners to find global solutions to solve the global challenge of a reliable and sustainable carbon-neutral energy future. As the first big step forward, we launched EconiQ™ – our eco-efficient portfolio for sustainability designed to deliver exceptional environmental performance compared to conventional solutions.
In August 2022, we unveiled the world’s first eco-efficient 420-kiolovolt (kV) circuit-breaker, a breakthrough technology that marked a significant milestone in our accelerated EconiQ high-voltage portfolio roadmap.
Discover our EconiQ high-voltage portfolio that eliminates SF₆ with reliable and scalable solutions for the lowest carbon footprint.
Hear our industry experts share their insights about eco-efficient echnologies as well as the obstacles and success stories that accelerate the energy transition.
