Siemens Energy will supply in-turbine distribution transformers for China’s first commercial high-voltage offshore wind farm, the first phase of China Huadian Corporation (CHD) 300MW Yuhuan project in Taizhou in the south-eastern province of Zhejiang.

Transformers convert electricity generated by a wind turbine to the requisite voltage level for power transmission on high-voltage lines and cables. The switch to higher-voltage transformers at 66 kilovolts comes as developers also in China increasingly opt for stronger wind turbines, which are already customary at European offshore wind orders.
