The unique feature of 20KW wind turbine
1. SCF (Supercritical Generator Technology) generator technology as core, Feature is extremely light &small&fasting&stable with higher power efficiency .
2. Adopt SKF (Svenska Kullager Fabriken) bearings, which have a 15 years life span without maintenance.
3. Smart Intelligent yaw shaft system has designed with sensor to detect speed&Rpm&angle &tempreture of genratror,speed&direction of wind etc.
4. PLC controller system(Smart&Intelligent) with touch screen, which can automatically seek wind direction, drifts off the blades from strong wind direction to protect the system and constantly monitor generator working status, Monitoring rotation speed, generator temperature, wind speed and direction etc. All data will be transmitted to control center and easy view control with the touch screen.
5. One international patents,Six National patents and ensure the perfect performance.
