The wind turbine is notable for featuring LM Wind Power-designed 75-metre blades that, with Siemens, jointly hold the current record as the world's biggest.

The two pitch-controlled variable-speed prototypes with 154-metre rotor diameter were installed at Longyuan Power's 150MW Rudong project late last year.

Haizhuang chairman Yang Benxin revealed that the company has also set up a research and development centre in Denmark.

Yang said the company had spent three years developing the turbine alongside Dutch engineering firm Mecal, KK-Electronic from Denmark and German offshore specialist Lehnhoff Consulting.

The turbine features large bearings, gearbox, high-speed permanent magnetic generator, and full power converter. The turbine head, with compact structure, is 15% lighter than other 5MW turbines.
