WinWinD 3 - Simply productive!
If you'd like to know more about us and our new WinWinD 3 turbine, please fill in the Sales contact form. We will get back to you as soon as possible.
WinWinD 3 is a completely new 3 MW utility class wind turbine taking the integrated power unit concept to a new level. It offers exceptional productivity and reliability in all wind classes. With a new 120 m rotor diameter, the turbine sets new productivity standards even for low wind speed sites. A substantially lighter nacelle weight makes the installation effortless and cost efficient.
What is WinWinD 3?
WinWinD 3 is a pitch regulated upwind wind turbine with active yaw and three-blade rotor. Thanks to three different rotor sizes, the turbine is suitable for all three wind classes.
Due to considerably lighter turbine weight, WinWinD 3 installation and logistics costs are optimized. The weight reduction is achieved by optimized turbine design, a sophisticated control system and a more maintenance friendly layout.
Thanks to intelligent design including sophisticated loads control, a high energy yield is achieved in all wind classes.
Reliability has been a key target in designing the new WinWinD 3. We have taken the next step with WinWinD's integrated power unit concept, where the main bearing transfers the rotor loads directly to the main casing of the supporting structure. This keeps the whole drive train free from deformation, providing high reliability. The integrated power unit, comprising the main bearing, planetary gear-box and permanent magnet synchronous generator, eliminates the unreliability of high-speed components.
WinWinD turbines fulfill the most demanding grid code requirements. This is achieved with our own control system and full conversion inverters.
WinWinD 3 turbines are IEC type certified by GL Renewables.
