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.

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.
