Technical FAQs 4

What is econiq breaker technology?

For Hitachi Energy, this is the very first frame agreement globally for its EconiQ eco-efficient breaker technology. Hitachi Energy today announces it will deliver the world's first sulfur hexafluoride (SF₆)-free 550 kV gas-insulated switchgear (GIS) to the Central China Branch of the State Grid Corporation of China (SGCC).

Does Hitachi energy offer high-voltage switchgear and breaker solutions?

Hitachi Energy offers a comprehensive range of high-voltage switchgear and breaker solutions up to 1200 kilovolts AC and 1100 kilovolts DC.

Will Hitachi energy install Italy's first 420 kilovolt sf6-free circuit breaker?

Hitachi Energy will collaborate with Tirreno Power to install Italy’s first eco-efficient 420-kilovolt (kV) SF₆-free circuit-breaker. Manufactured in Italy, the groundbreaking equipment made at Hitachi Energy’s factory in Lodi is set to be installed in 2025.

How does econiq technology accelerate China's power grid decarbonization?

Innovative EconiQ technology accelerates China's power grid decarbonization. Innovative switchgear enables phaseout of SF6, a greenhouse gas 24,300 times more potent than CO2, staying in the atmosphere for over 1,000 years. TenneT’s Maasbracht substation has the longest SF6-free gas-insulated line installation in Europe.
