Planetary gear wind turbine V117-4.2 MW™

V117-4.2 MW™ is designed for medium to high wind speeds, and it boosts performance by 13 percent compared to V117-3.45 MW. Applying the existing upgraded gearbox from V136-3.45 MW and V126-3.45 MW Htq, the V117-4.2 MW™ is able to withstand extreme wind conditions, making new sites possible for wind energy projects. 4 MW The Vestas 4 MW platform sets new standards for onshore wind performance within regimes ranging from very strong wind and typhoon conditions to ultra low wind. 61 Countries The Vestas 4 MW platform has been installed in 61 countries since 2010. +88 GW The performance and versatility of the 4 MW platform has been proven with more than 88 GW installed since 2010. Options available High Wind Operation Power Optimised Mode up to 4.2 MW (site specific) Load Optimised Mode down to 3.6 MW Condition Monitoring System Service Personnel Lift Vestas Ice Detection Low Temperature Operation to - 30°C Fire Suppression Vestas Shadow Flicker Control System Vestas Bat Protection System Nacelle Hatch for Air Inlet Aviation Lights Aviation Markings on the Blades Typhoon The V117-4.2 MW™ Typhoon offers maximum energy production in medium to high wind speeds. It strengthens the 4 MW platform’s performance in extreme wind conditions expanding reach into areas with very strong wind and typhoon type weather. With use of Load Optimised Modes, the V117-4.2 MW™ Typhoon can be sited at complex sites with turbulence levels exceeding IEC class A.
