Our advantages

1. The structure of the wind wheel is simple, the hub adopts mature fixed slurry structure, no complex moving mechanical devices, maintenance free, very low failure rate.
2. All parts are made of conventional national standard parts, which can be purchased anywhere in the world.
3. Adopt three-phase transmission slip ring to conduct electricity and no twisted cable phenomenon.
4. The rotor vertical shaft has no rigid driving mechanism and only USES conventional bearings. This structure can easily resolve the shaking and vibration caused by unstable airflow, which is conducive to improving the life of the wind turbine.
5. Generator efficiency is above 90% and wind energy utilization coefficient is 42%.

6. Unique simple control mode, automatic windward, effectively improving the working efficiency of the wind turbine; Make full use of aerodynamic design, so that the wind turbine will automatically deflect the wind wheel 90 degrees beyond the safe wind speed, completely against the wind, to ensure that the wind turbine operating under the safe wind speed; The tail rudder plate adopts the patented rotating shaft working mode. In case of failure of the control system, the rotating shaft mechanism can ensure that the wind turbine will not be damaged due to high wind speed. At the same time with triple protection, completely eliminate the occurrence of failure!


About us


Based on 40 years of motor development technology advantage and superior military tradition, the company introduced the advanced 1.5MW variable-speed constant-frequency doubly-fed asynchronous generator technology from Germany in 2005, to march into the wind power market with high starting point. Now, after years of development, the company has completed the transformation of imported technology process and realized the localization, forming the production capacity of 1MW, 1.5MW, 2MW, and 2.5 MW wind power generators. At the same time, in order to meet the requirements of different running conditions, the company has developed the lower temperature type, salt-spray proof type, and high-altitude type wind power generators on the basis of normal temperature generator. By 2014, a total of 4000 wind power generators and more were delivered to the wind fields and put into operation respectively in Xinjiang, Gansu, Inner Mongolia, Jilin, Shandong, Ningxia, Jiangsu, Hebei, Harbin, Shanxi, Liaoning, Henan, Heilongjiang, etc.; the units were functioning well and were highly appreciated by users. The company has a professional after-sales service team, to provide the timely, thoughtful and accurate technical guidance services for wind power generator users, and help them solve the problems encountered in the operation.
