D3200-155

Low Maintenance Costs

• Utilizes a direct-drive technology path, eliminating the need for regular replacement of gear oil, filters, and generator brushes, resulting in shorter maintenance time.

• Fewer components in the unit result in lower failure rates, shorter scheduled downtime, and minimal energy loss.

• Fewer consumables required for maintenance, leading to lower overall maintenance costs.

Low Engineering Costs

• Compared to 2.0/2.5MW units, reduces the required number of installations by 17%–34%, significantly lowering costs for land acquisition, roads, installation, and collection lines.

Superior Power Generation Performance

• Equipped with a large 155-meter rotor diameter and adjustable single-unit capacity of 3.0–3.2MW, achieving over 2100 annual operating hours at an average wind speed of 5 m/s.

• Over 60 years of experience in the R&D and manufacturing of large-scale power generation equipment, with generator efficiency 1%–3% higher than domestic competitors.

• High-efficiency blade design featuring advanced technologies such as serrated trailing edges and vortex generators, achieving a Cp value above 0.49.

• Proprietary control system perfectly matched with blades, maximizing energy capture while controlling loads.

High Safety and Reliability

• The direct-drive technology path has a shorter transmission chain and no high-speed rotating parts, enhancing reliability.

• No high-speed lubrication system or generator slip rings, reducing fire risk and improving safety.

• Dual-safety chain design with patented technology, eliminating overspeed incidents and further enhancing safety.

• Proprietary control system with an average mean time between failures (MTBF) of over 2000 hours.

• Patented magnet protection technology prevents demagnetization and detachment, with zero downtime for high-power direct-drive generators.
