Hummer wind turbine adopts two SKF (Svenska Kullager Fabriken) bearings which are produced by the largest bearing manufacturer in the world, with the perfect internal geometric structure, known for its life-time endurance and reliable quality. Ordinary bearings need to be changed every two or three years, while SKF bearings can greatly reduce the maintenance costs on this matter.  

 

The design of the rotor blade of Hummer wind turbine absorbs the highlights of the small aircraft’s airfoil, which is compliance with the aerodynamic standards. It provides a more aesthetic look and a higher efficiency and reduces the noise production as much as possible.

 

Hummer 2000W wind turbine adopts the double braking protection system, which are the yawing mechanism and the electromagnetic braking system to regulate the rotation of the wind turbine. It is safe and convenient to shut down the whole system both manually and automatically.
