Hitachi ABB Power Grids WindSTAR, liquid-filled transformers are ideal solution for fixed and floating offshore wind applications. Their reliable, energy-efficient and compact construction is well suited for installation in wind turbine towers or nacelles.
As turbine size increases for offshore (8 MW and above), turbine transformers must remain compact and lightweight with a minimal footprint, while also meeting specific application needs, mechanical structural constraints and costs.
Based on 36 kV class established solution for large offshore turbine, Hitachi ABB Power Grids has developed a transformer able to step up voltage at world record of 66 kV and meet the most stringent electrical and mechanical requirements. With its WindSTAR transformer, Hitachi ABB Power Grids is bringing step change in the scale of power and voltage.
