New Siemens onshore wind turbine offers less noise at optimum performance

High performance at low to medium wind speeds – that’s what the new Siemens low noise SWT-3.3-130LN wind turbine offers customers. The new model operates at a reduced rotor speed compared to the SWT-3.3-130, and includes aerodynamic addons to its rotor blades. Utilizing these add-ons, it can be operated at a noise level of 104.9 decibels. The new machine will be available in early 2017 in parallel with two additional onshore models launched by Siemens at the WindEnergy 2016 trade show in Hamburg. ….
