Welcome to the Future of Wind Power: 72.5 kV Gas-Insulated Substations

The offshore wind market is seeing significant growth with more powerful windfarms gradually moving into deeper waters, much farther from shore. Our 72.5 kV GIS type F35 can double the voltage as compared with medium-voltage technologies. Energy from a wider area can be handled by a single platform using 66 kV alternating current (AC), reducing energy losses. This versatile F35 GIS can be specifically arranged for offshore wind turbines as a wind module and is available with SF₆ or g³, our SF₆-free alternative.

SF₆-Free Gas-Insulated Substations

As global efforts toward sustainable power supply intensify, our cutting-edge electrical grid technology ensures alignment with this critical transition. By utilizing g³ gas instead of SF₆, we are committed to drastically reducing the carbon footprint of the GIS —achieving a 99% reduction in CO₂-equivalent of the gas— while maintaining dimensions, performance, and reliability. The F35g-72.5kV SF₆-free GIS is part of our GRiDEA portfolio of solutions designed to accelerate the decarbonization of the grid.

Compact and Efficient Design

Our F35-72.5kV SF₆-free GIS are meticulously engineered for compactness, minimizing spatial demands without sacrificing performance nor accessibility. This efficient design facilitates seamless integration into offshore environments, where space is limited and reliability critical. The use of cable connections according EN 50181 type F is one the novelties. The GIS module supporting frame not only improves space utilization but also simplifies installation and maintenance processes, thereby reducing overall operational costs.

Engineered to Withstand Harsh Environments

Beyond decarbonization and spatial benefits, our F35-72.5kV GIS is robustly designed to withstand saline environments as well as the high shocks and accelerations at every stage of the construction, transport, installation, commissioning, and in the challenging conditions often encountered in offshore installations. Through advanced engineering and rigorous testing, including seismic assessments up to 1g acceleration conducted at a CESI Laboratory, our substations are built to maintain operational integrity under these demanding circumstances. This resilience reflects our unwavering commitment to delivering solutions that surpass industry standards, ensuring the reliability of your wind turbines.
