18MW Direct-Drive

High Economic Efficiency

• Dual main bearing outer ring rotation structure ensures even load distribution on the main shaft for smoother and more efficient operation.

• Converter and boost transformer available in 35kV/66kV options, shortening installation and commissioning periods.

High Safety and Reliability

• Offshore turbines employ a dual-drive electric pitch control system with triple-row column bearings, providing enhanced safety, stability, and reliability in harsh conditions.

• The turbine’s 126-meter carbon-glass hybrid blades, among the longest in the industry, feature a main beam with carbon fiber pultrusion technology, ensuring optimal safety and durability.

• Ultra-high power density generator design achieves a unit torque weight of less than 15kg/kNm, maximizing efficiency and stability.

• Dual-bearing structure layout distributes load evenly across bearings, enhancing component rigidity, minimizing deformation, and maintaining a safety factor exceeding 3.0 for all bearings.

• Offshore generators use internal air-to-air cooling to prevent salt mist corrosion, supporting high reliability and longevity.

• External rotor permanent magnet direct-drive system operates at low speeds without a gearbox, enhancing overall safety and stability.
