LTW90

500 – 2.000 kW

How much wind does a wind turbine need? Less than you’d think: the LTW90 wind turbine by Leitwind was specially designed with state-of-the-art technology for low-wind sites. Thanks to the large rotor surface area, this wind turbine ensures significant power generation even in less favourable positions and is perfectly suitable for a wind class of up to IIIA+. It’s the ideal solution for all clients looking for a wind turbine with outstanding performance – the LTW90 is available at nominal powers from 500 to 2.000 KW.

THE WIND TURBINE IN DETAIL

Leitwind WIND TURBINES

  • The blades capture the power of the wind in their rotational motion.

  • The hub transforms the motion of the blades into mechanical power. It also hosts the pitch system.

  • The pitch system controls the power captured by the blades (by varying their angle of attach) and acts as main braking system.

  • The Direct Drive generator is integrated in the main structure and converts mechanical to electrical power.

  • The main frame connects the Direct Drive generator to the tower, it carries the control system and the yaw system.

  • The yaw system allows the nacelle to turn relative to the tower, keeping it upwind.

  • The tower elevates and supports the rest of the structure into the wind. It grants access to nacelle and shelters the energy transforming station at its root.

  • The transforming station accommodates the power electronic and the MV transformer for the connection to the electrical grid.
