FEATURES:

1. Security. Using the vertical blade and triangular double-fulcrum design, the main force points concentrated in the hub, so blade lose, broken and leaf flying-out and other issues have been a better solved.

2. Noise. The use of horizontal rotation and blade application aircraft wing design, making the noise reduced to an unperceivable level in natural environment.

3. Wind resistance. Horizontal rotation and triangular double fulcrum design make it only bear a small wind pressure, so that it can withstand 45 m/s super typhoon.

4. Rotation radius. Because of its design structure and special operating principle, it has a smaller radius of rotation than other types of wind turbines, it saves space, while improving efficiency

5. Power generation curve characteristics. Start wind speed is lower than other types of wind turbines, the power generation increasing rate is relatively gentle, so between 5 to 8 meters wind speed range, it could produce 10% to 30% power than other types of wind turbines.

6. Effective wind speed range. special control principle makes its effective wind speed range expened to 2.5 ~ 25m / s, in the maximum use of wind resources, obtain a higher power generation, improve wind power investment economics.

7. Brake device. The blade itself has speed protection, and can configure manual mechanical and electronic brake meantime, in the absence of typhoon and super gust area, manual brake is enough.

8. Operation and maintenance. Direct drive type permanent magnet generator, without gear box and steering mechanism, regularly(usually every six months) check the connection of the running parts.

9. Appliacation. The turbine could be installed near facilities, such as residences, parks, schools, building rooftops, roads and walking street, etc
