Paris, FRANCE – The 420 kV circuit-breaker leads to transmitting large amounts of electricity over long distances while eliminating significant volumes of SF6.

Hitachi Energy has announced that they have unveiled the world’s first eco-efficient 420-kilovolt (kV) circuit-breaker in conjunction with CIGRE Session 2022. This technology marks a significant milestone in its accelerated EconiQ™ high-voltage portfolio roadmap that was announced at CIGRE Session 2021.

According to Hitachi Energy, the 420 kV circuit-breaker leads to transmitting large amounts of electricity over long distances while eliminating significant volumes of SF6.

“This 420 kV breakthrough is a demonstration of our technology that is reliable and scalable to reach ultra-high-voltage levels with the lowest carbon footprint,” says Markus Heimbach, Managing Director, High Voltage Products within Hitachi Energy. “We are enabling our customers and the industry as a whole to rapidly transition to eco-efficient solutions to advance a sustainable energy future for all,” he added.
