SHENZHEN KRY ELECTRICAL EQUIPMENT CO.,LTD.engges in power equipments development and manufacture for many ears ang creates a new generation of revolutionary & high efficient wind power systems successfully after close focus on wind power market and long time of development & verification.The major vane and wind ball models have advantages in comparison with traditional wind power products.
1.Large wind scope for power generation can utilize all directions of wind and operate continuously in a
big range of wind speed.
2.No limit to wind direction
The patent design of vane & wind ball generators is made of light composite.They’er light ,anti-uv ,cold & hot resistant ,acid-proof and has no limit to wind directions.
3.High efficiency of power generation
Coil power generators have small size and multi-coils twisted in double and improve power generation efficiency
4.Wind ball generators take flying move structures
The generators adjust power generation automatically based on the turning speed of wind shaft till catching the wind speed limit and protect modules safe operation without any additional energy consumed.
5.Soundless operation,no noise or vibration,small wind matching sound and stable turn.
