Pitch System

• Super-capacitor as back-up power ensures safety stop during grid loss;
• Pitch motor and control cabinet located inside the hub makes well lightning protection and sealing.

Gearbox

• Main shaft integrated inside the gearbox making compact structure and site Alignment unnecessary;
• Well lubrication for the main shaft with long lifetime;
• Observation holes for each stage are easy for maintenance;
• Rear-located slip ring improves operational reliability.

Noise Decoupling System

• Two layers of vibration absorber are located at the connection between gearbox and main frame for noise decoupling.

Oil Cooling System

• The oil-to-air heat exchanger is cooled down by external air.
• This brings better cooling and avoids contamination of gearbox hot oil-air.

Ventilating System

• The axial fan located in the rear of nacelle reduced temperature inside the nacelle.

Generator

• High-efficient water-cooled generator with small size;
• Technologies including insulation cover and multi-point earthing eliminate the influence of axial current.
• Nature air cooling system has the advantage of less power consumption, noise, maintenance and well anti-sand effect.

Yaw System

• Yaw system adopts self-lubricated sliding pad.
• No extra lubrication system and yaw brake are needed.

Nacelle Sealing

• Spinner disc in the front of nacelle cover prevents the entering of sand and rain water.

Converter at Tower Base

• Air-cooled converter located at tower base with reliable operation.
