Turbine for low- to medium-wind speed sites

Jun 01,2015
Alstom has introduced its 3MW ECO 110 wind turbine, one of the most powerful onshore wind turbines, specifically designed to ensure the highest energy production on low- to medium-wind speed sites. The ECO 110 features a 110m-rotor diameter, one of the largest rotors available today for onshore applications, to capture even greater amounts of wind on a given site and maximize the energy yield of a turbine. The ECO 110 can produce enough energy for 2000 households while avoiding the production of 7000 tons a year of CO2. Its 53 metre-long blades, over half a soccer field long, have been designed to capture more power more effectively—which means fewer turbines and less land space are required to generate the same amount of power. Alstom’s wind turbines are based upon the unique ALSTOM PURE TORQUE rotor support concept, which protects the gearbox and other drive train components from deflection loads. The concept fully separates the gearbox from the supporting structure ensuring that only torque is transmitted through the shaft to the gearbox, and all deflection loads are transmitted directly to the tower. Most conventional rotor support concepts tend to turn gearboxes into consumables; whereas, ALSTOM PURE TORQUE continuously delivers higher gearbox reliability, higher operational availability, and lower maintenance costs.
