High-Voltage Switchgear & Breakers

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). This pioneering achievement marks a significant step toward decarbonizing the power grid and contributes to China's target of achieving carbon neutrality by 2060.

In this episode, we break down the newly unveiled EconiQ roadmap of the future:

• The new rating additions and its significance
• What this means for the reliability and sustainability of power grids

Hitachi Energy's EconiQ switchgear is a key component in making Japan's power grids sustainable.

Hitachi Energy is collaborating with CHN Energy, a Chinese state-owned energy company, to reduce greenhouse gas emissions in their operations.

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. The move marks a significant step forward towards a sustainable electricity network in Italy.

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.

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

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

On June 20, the breakthrough EconiQ dead tank breaker was delivered to Eversource during an exclusive event at Hitachi Energy’s state-of-the-art factory in Mount Pleasant, Pennsylvania, USA.

The agreement affirms the need to reduce F-gas emissions and ensures at the same time that high-voltage substations will remain safe, reliable, and compact.

Shifting the global electricity supply toward carbon-free sources is essential to reduce greenhouse gas (GHG) emissions and a priority in combatting climate change. The world added 295 gigawatts (GW) of renewable

Breakthrough technology unlocks the widest range in eco-efficient switchgear applications and accelerates the energy transition

Fingrid takes yet another step to phase out sulfur hexaflouride (SF₆) from its high-voltage equipment. EconiQ Live Tank Breaker – LTA for 145-kilovolt (kV) to be installed at Heinola substation in Finland will help to do just that.

The innovation called EconiQ^™ retrofill uses eco-efficient gas mixture to support National Grid in achieving their sustainability targets.

SP Energy Networks is contributing to achieve the decarbonization goals by avoiding the addition of over 3,000 kilograms of sulfur hexafluoride to the transmission electricity network.

Hitachi Energy has signed a frame agreement with Norway’s major distribution grid company, BKK Nett to install EconiQ™ Live Tank Breakers (LTA) 145 kV in more than 10 substations in the western region. For Hitachi Energy, this is the very first frame agreement globally for its EconiQ eco-efficient breaker technology.
