EconiQ®

The country has taken a major step toward a cleaner grid with the commissioning of its first 420 kV SF₆-free dead tank circuit breaker.  

Hitachi Energy announces today the signing of contracts with Statnett, the Norwegian power system operator, to deliver eco-efficient grid connection solutions in the greater Oslo area.  

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). 

Hitachi Energy has booked orders for over 65 units of its groundbreaking EconiQ 420 kV Dead Tank Breaker and the world is taking note.

Hitachi Energy will supply its pioneering 380 kV EconiQ gas-insulated lines (GIL) to upgrade TenneT’s legacy substation in Maasbracht, a small town on the banks of the river Maas in southeastern Netherlands. 

Hitachi Energy will provide the world’s first SF₆-free 420 kV GIS and a state-of-the-art modular prefabricated grid connection solution at a key node at TenneT’s power grid in Germany.

Hitachi Energy will install the world’s first eco-efficient EconiQ 420 kV circuit breaker for Eversource in the US. A game-changing technology that eliminates sulfur hexafluoride (SF₆), this will be the first 420 kV SF₆-free circuit breaker installation in the country.

Hitachi Energy and Linxon are collaborating to strengthen London Power Tunnels (LPT), a key power infrastructure project that will ensure reliable, clean electricity supply for England’s capital city.
