Product details:
1.appearance:
1)streamlined fiber glass nacelle
2)stable operation
2.hydraulic tower
1)patented
2)easy installation and maintenance for WTGS
3)save expenditure from hiring the crane.
4)only involving 20mins to finish the erection and lay-down
3.DC motor
1)normal yaw even under strong wind speed.
4.control units
1)Mitsubishi PLC
2)outstanding anti-jamming
3)intelligent control has been achieved by combine various sensors.
5.hydraulic brake
1)the pressure will be increased gradually when braking,which will minimize the
damage caused by blade inertial rotation.
2)the pressure can be maintained once braking.
3)longer lifespan compared to electric brake.
6.generator
1)abundant in yield
2)low start-up torque
