China’s Dongfang Electric (DEC) has completed the assembly and testing of key subsystems for its first 7-MW typhoon-resistant offshore wind turbine
The turbine was independently developed by DEC at its Fujian manufacturing base.
The turbine, the DEW-D7000-186, was custom-developed by DEC and is suitable for sea areas with low wind speeds, strong salt spray corrosion and for use in typhoon-prone areas. The 7-MW turbine has a rotor diameter of 186 m.
“At present, it is the largest Chinese-developed unit capable of operation in typhoon-prone regions,” said the company, “and has the largest rotor diameter of any turbine suitable for low and medium wind speed regions.
