CSIC Haizhuang will install the prototype at the Rudong demonstration offshore wind farm, in east China’s Jiangsu province. It will be connected to the grid at the end of the year, said CSIC chairman Yang Benxin.
Yang said the company has spent three years developing the turbine, alongside Dutch engineering firm Mecal, Denmark's KK-Electronic and German offshore specialist Lehnhoff Consulting.
The turbine features large bearings, gearbox, high-speed permanent magnetic generator, and full power converter. The turbine head is said to be 15% lighter than other 5MW turbines.
Yang said the turbine is suitable for 90% of Chinese wind farms, both onshore and offshore. So far, Sinovel and Guodian United Power have produced 6MW offshore turbines, while XEMC has produced a 5MW offshore turbine.
CSIC is a relatively minor player in China with only 1.4% of the market.
