*1, Curved blade design, utilizes wind resource effectively and obtains a higher power generation.
*2, Coreless generator, Horizontal rotation, and aircraft wing design reduce the noise to an unperceivable level in the natural environment.
*3, Wind resistance. Horizontal rotation and triangular double fulcrum design make it only bear a small wind pressure even in strong wind.
*4, Rotation radius. smaller rotation radius than other types of wind turbines, space is saved while efficiency is improved.
*5, Effective wind speed range. exceptional control principle expended the wind speed to 2.5 ~ 25m/s, utilizes wind resources effectively, and obtains a higher power generation.
