Key Features

1. Low start-up wind speed - 1.8m /s, greatly improves efficiency.
2. Low rotating speed, 40 rpm to generate rated power.
3. No noise, <63db at 10m distance.
4. Blades to regulate angles automatically every 30 seconds, to increase the windward area at low speed and decrease it at fierce wind.
5. Hydraulic tower for easy installation and maintenance.
6. Remote monitoring.
7. Optional heating blades. 

Rated power: 20kw

Rated voltage: AC360V-AC400V

Startup wind speed: 1.8m/s

Rated wind speed: 9m/s

Survival wind speed: 28m/s

Rated rotating speed: 60rpm

Blade quality: 1pc

The angle of the blade can be adjusted by the eccentric rod, controlled by the controller that collects data from anemometer and dogvane.

Under normal wind speed, the blades obtain maximum windward area by just face toward the wind direction. Then the rotation speeds up to achieve the maximum wind utilization.

However, under extreme high wind the blades decrease its windward area to slow down the rotation to protect the device.
