G5000-140

High Economic Efficiency

• The blades use a blunt trailing edge airfoil design, enhancing the unit's power generation capability, with a cut-out wind speed of up to 30 m/s.

• Advanced control strategies tailored for offshore environments ensure high-efficiency output from the unit.

• Major components are designed for replacement and maintenance within the nacelle, reducing overall machine costs, improving economic performance, and facilitating offshore maintenance.

• Utilizes an integrated simulation technology for the turbine, tower, and foundation, optimizing the design and effectively reducing construction costs of offshore wind farms, thereby lowering the Levelized Cost of Energy (LCOE).

High Safety and Reliability

• Transmission chain uses a gearbox with a high-speed permanent magnet generator and full-power converter, achieving high transmission efficiency.

• Fully enclosed nacelle with internal circulation cooling system effectively prevents corrosion of internal components from external salty air.

• Exceptional typhoon resistance with an active typhoon protection strategy that reduces loads on the tower and foundation.

• Dual-circuit electrical system allows half-power operation in case of a single circuit failure, enhancing Mean Time Between Failures (MTBF).

• Dual safety chain design with patented technology and multiple redundancies in critical systems.

• Equipped with Dongfang's proprietary control system, reducing failure rates for the unit.
