6.2M152 – A proven powerhouse

Larger turbine, higher yield: our 6.2M152 makes offshore power even more economical. Based on the tried-and-tested 6.2M126, our engineers have optimised the gearbox, rotor and machine carrier so that the offshore turbine now delivers up to 20 per cent more yield at a wind speed of 9.5 m/s.
