Hitachi Energy has unveiled an eco-efficient 420-kilovolt (kV) circuit-breaker.
The EconiQ high-voltage portfolio uses technology that eliminates sulfur hexafluoride (SF6), a greenhouse gas. Over time, it has been successful in continuously increasing the voltage levels of its EconiQ high-voltage portfolio.
The EconiQ 420 kV circuit-breaker is able to transmit large amounts of electricity over long distances while eliminating significant volumes of SF6. It will be used in both dead tank breaker (DTB) and gas-insulated switchgear (GIS).
The EconiQ DTB and GIS are expected to be released at the end of 2022, on track with the company’s roadmap.
