Hitachi to provide Japan’s first SF6-free 300 kV circuit-breakers to Chubu Electrical Energy Grid
TOKYO, Dec 9, 2024 – (JCN Newswire) – Hitachi, Ltd. introduced at present that it obtained an order for 5 items of Hitachi Power’s sulfur hexafluoride (SF6)-free EconiQ&commerce; 300 kilovolt (kV) circuit-breaker from Chubu Electrical Energy Grid. That is the primary venture in Japan the place SF6-free circuit-breakers will probably be put in at voltages of 275 kV and above. It marks a milestone in attaining sustainable energy grids in Japan and Chubu Electrical Energy Grid’s ambition of decreasing emissions to zero by 2050. The SF6-free EconiQ circuit-breaker reduces CO2-equivalent emissions from the insulating fuel by 99.3 %.
SF6 fuel has wonderful insulation and switching efficiency and has been used for many years in energy grids. It additionally has a world warming potential of 24,300 occasions larger than CO2 and stays within the environment for greater than 1,000 years if it leaks from the gear.
Governments across the globe are engaged on laws to section out the set up of recent SF6 fuel gear to deal with local weather change. Nonetheless, no laws relating to eliminating SF6 fuel gear in Japan exist but.
With Japan’s electrical energy demand anticipated to extend attributable to electrification and the enlargement of knowledge facilities, it turns into essential to strengthen the ability grids whereas decreasing greenhouse fuel emissions. SF6-free switchgear, akin to Hitachi Power’s EconiQ, is the one answer to this two-fold problem – it has confirmed reliability, stays compact, and has the bottom carbon footprint.
In 2022, Chubu Electrical Energy Grid introduced its coverage to undertake SF6-free circuit breakers as much as 77 kV when they’re changed. At present, Chubu Electrical Energy Grid introduced a progressive coverage to speed up its decarbonization initiatives by adopting SF6-free circuit breakers for 275 kV and above.
Hitachi Power launched EconiQ high-voltage merchandise in 2021 to satisfy the demand for SF6-free gear. The EconiQ high-voltage portfolio eliminates greenhouse fuel emissions by changing SF6 fuel with an eco-efficient various fuel whereas sustaining the identical efficiency, measurement, security, and reliability as typical gear utilizing SF6 fuel. The corporate is progressively increasing its EconiQ high-voltage product lineup. It has already developed SF6 gas-free merchandise for grid-level voltages as much as 550 kV. About Hitachi, Ltd.
