China’s Sewind Co., one of its top five wind turbine manufacturers, produces 1.5 to 2 MW turbines.

Moog Industrial Group will provide 400 electric pitch-control systems for China-based Sewind Co. Ltd's 2-MW wind turbines. The controls will go into on-shore and intertidal models. Sewind Co., one of the top five companies in China's wind-energy industry, specializes in the design, manufacturing, and sale of large units.

Pitch systems control blade positions on wind-turbine rotors to ensure highest possible power capture and to protect the wind turbine. The pitch-control servodrives used in these systems operate under extreme temperature conditions within switch cabinets in the wind turbine rotor hubs, guaranteeing reliable operation. Moog says its pitch systems withstand extremely high mechanical loads in rotating turbines, while improving turbine operating efficiency.

“With worldwide emphasis on renewable energy sources and building a low-carbon economy, wind turbine operators will be searching for ways to increase wind turbine operation time,” says Moog's general manager for the Asia Pacific Region Sean Gartland.

Sewind is a joint venture of the Shanghai Electric Group Co. Ltd. and China Huadian Engineering Co. Ltd. Sewind headquarters are in Shanghai with production bases in Shanghai and Tianjin.
