Superior Power Generation Performance

• Features a large 148-meter rotor diameter with a single-unit capacity of 3.5MW–4.0MW, capable of enhanced performance in low temperatures, achieving over 3400 annual operating hours at an average wind speed of 7.5 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.

Low Engineering Costs

• Compared to 3.0MW units, it reduces the number of required installations by 25%, significantly lowering costs for land acquisition, roads, installation, and collection lines.

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.
