Horizontal-axis wind turbine SE16445/SI-16450

three-bladedonshorefree-standing tower

4. XMW~6.XMW products are designed for middle to high wind sites, with power rating from 4.2MW to 6.XMW, with rotor diameter till 172 m, and hub height till 140m. Double-fed technology is applied for 4.XMW~6.X MW platform Rigorous product design and third-party certification, as well as mature and reliable supply chain, make the units highly reliable. Sany Renewable Energy is the first OEM to assemble the transformer on the nacelle platform in China, effectively reducing the cost of wind farms; Longer blades are applied to capture more wind energy, and combined with control technology of smart wind farm and smart wind turbine, energy production can be significantly increased; Advanced control strategies are adopted to lower foundation loads, tower weight, and LCOE. With platform-based design and modular configuration of each component, the wind turbines can be widely installed. With ultra-low load design technology and digital self-optimizing iterative design technology, the load of the wind turbine, together with the weight, is effectively reduced. The weight indicators of the whole series of 4.XMW~6.XMW are ahead of domestic competitors. Modular design can split transportation and lifting, which can greatly save costs for lifting and crane rental. Transformer assembled in the nacelle helps to save the cost of cables from box to converter, ground construction of box-transformer is not required. The technology of nacelle-fixed transformer enables cost reduction of land acquisition and land use, effectively help to lower elec-trical losses, shorten construction maintenance period, and reduces wind farm cost.
