Eco-efficient switchgear supports the energy transition
At CIGRE Session 2022, Hitachi Energy launched the world’s first eco-efficient 420 kV circuit breaker. This is the first SF 6 -free 420 kV circuit breaker fully tested in terms of the IEC and IEEE standards for 63 kA, 5 000 A, 50 and 60 Hz. The breakthrough technology marks a signifi- cant milestone in Hitachi Energy’s accelerated EconiQ™ high voltage portfolio roadmap, which was announced at CIGRE Session 2021. For over two decades, the company has been in- vesting in eco-efficient alternative solutions to sulphur hexafluoride (SF 6 ) including the world’s first 170 kV eco-efficient gas-insulated switchgear (GIS). It uses this game-changing technology in its EconiQ high voltage portfolio, to eliminate SF 6 , which is a greenhouse gas. Over time, it has successfully increased the voltage lev- els of the EconiQ high voltage portfolio. The launch of the EconiQ 420 kV circuit breaker also marks a key milestone in the industry – enabling the transmission of large amounts of electricity over long dis- tances while eliminating significant volumes of SF 6 . This innovation is the key enabler to achieving a wide range of EconiQ switchgear applications, and will be used in both dead tank breaker (DTB) and gas-insulated switchgear (GIS). The EconiQ DTB and GIS are expect-
ed to be released at the end of 2022, on track with the compa- ny’s roadmap. Markus Heimbach, Managing Director, High Voltage Products at Hitachi Energy, says, “This 420 kV breakthrough is a demon-
stration of our technology, which is reliable and scalable to reach ultra-high-voltage levels with the lowest carbon footprint. We are enabling our customers and the indus- try as a whole to transition more rapidly to eco-efficient solutions to advance a sustainable energy future for all.” EconiQ is Hitachi Energy’s eco-efficient portfolio for sustainability, where products, services and solutions are proven to deliver exceptional environmental performance. Hitachi Energy has placed sustainability at the core of its purpose and is advancing a sustainable energy future for all. Its high voltage portfolio also includes EconiQ Retrofill, another world first in replacing SF 6 in existing high voltage equipment, and EconiQ gas-insulated current transformers. The EconiQ high voltage technologies are being widely adopted by key customers in Europe.
