Hitachi Energy’s specially designed transformer for floating wind turbines is capable of withstanding high vibrations and accelerations as well as avoiding the risk of oil-spills due to completely dry operation.
Hitachi Energy has developed and supplied first-of-its-kind Vacuum-Cast-Coil (VCC) dry-type transformer that is specially designed for floating, off-shore wind turbines. As a part of their recently announced portfolio of transformers for floating applications, these transformers will support in unlocking the vast potential of off-shore, floating, wind-power generation, thus enabling the transition to a sustainable energy future.
This unique transformer by Hitachi Energy has been installed in China's first floating wind turbine called ‘Sanxia Yinling Hao’ (Three Gorges Lead). This 5.5-megawatt wind turbine has been successfully put into operation in December 2021 at Yangjiang wind farm - off the coast of south China’s Guangdong Province. It was developed by China Three Gorges and Mingyang Smart Energy, a leading wind turbine manufacturer in China. The transformer installed in the wind turbine steps-up the electric voltage of the power generated by the wind turbine to enable its transmission to the offshore booster station. Thereby, the transformer becomes a key enabler in reliable transmission of clean, renewable, and sustainable energy.
