1.Product Features

1 . SCF Supercritical generator

Hummer’s wind generator adopts SCF supercritical technology which won a gold award in the 37th Salon Eureka in Brussels. This technology significantly reduces generator’s weight and size down to 25% to 30% of the traditional one, and the production efficiency is 25% to 30% higher. This ensures that the generator functions perfectly in small wind condition. 

 

2. Low noise

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.

 

3. Triple braking protections

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