Making low wind sites into successful energy sources
Low wind sites don’t have to mean lower return on investment. The SWT-DD-142 secures your investment by combining new and proven technology for a ground-breaking onshore innovation. The turbine is based on the tried and tested features of the existing Onshore Direct Drive technology - using the same components and electrical systems assures reliability and performance. The OptimaFlex product strategy enables unprecedented levels of flexibility both now and in the future.
Technological highlights
Hybrid carbon technology has created a lighter, longer blade with aeroelastic performance. Its pre-bent tip section reduces peak loads and structural stress while its airfoil design delivers high performance, giving it the highest annual energy production in its wind class. DinoTail® Next Generation and Vortex Generators then help to improve performance and cut acoustic noise emissions.
Turbine sensors continuously transmit data to the Siemens Gamesa Diagnostic Center, enabling the early detection of anomalies and preventing potential failures. By analyzing vibration patterns we can optimize your service plan and anticipate repairs before serious damage occurs.
