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 makes real that the weight and size of hummer 50kW generator are one-half of the traditional one, and the generator efficiency is improved from 0.22 ~ 0.28 to 0.42. This ensures that the generator functions perfectly in small wind condition.
2. NSK bearings
Hummer 50kW wind turbine adopts the NSK bearings which are produced by the renowned bearing manufacturer in the world, with the perfect internal geometric structure, known for its life-time endurance and reliable quality. As well as enabling smooth and quiet rotation, they also perform an important function by taking on the motor's load.
3. SIEMENS PLC integrated with Siemens module
Hummer wind turbine's controlling system adopts the smart touch-screen PLC (Programmable Logic Controller) which is integrated with Siemens controllig unit. The PLC will alarm and adjust the abnormal running status of the wind turbine automatically both timely and efficiently. Siemens module offers high reliability to our PLC and its customers worldwide can testify for that.
4. 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.
5. Triple braking protection
Hummer 30kW 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.
