Main Shaft

• Compact drive train; High efficient and reliable load distribution technology.

Pitch System

• Super-capacitor as backup power has the advantage of low temperature and fast response; pitch control system inside the hub makes well lightning protection and sealing.

Anti-Corrosion

• Micro-pressure system for offshore turbine prevents nacelle components from salt corrosion. Multi-stage filtration system has high-efficient salt separation.

Maintenance Crane

• Large components self -maintenance system for offshore turbine significantly reduces maintenance cost.

Rotor

• High-strength glass fibre blade with anti-wear on blade leading edge; reliable lightning protection; Safe and convenient maintenance access inside the spinner.

Generator

• High-efficient water-cooled generator with small size; Technologies including insulation cover and multipoint 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.

Tower Base Layout

• Main electrical equipments including converter and switch gear are located on the tower base platform. This layout efficiently separates the electrical equipments from vibration with easy maintenance. Water-cooled converter has high efficiency and reliability.
