For medium and low wind speed wind farm sites and for centralized and decentralized wind farms. 3.X MW - 4.X MW platform wind turbine products are designed for a wide range of wind and site conditions. The rotor diameters is available up to 183 meters, the height of hub is up to 140 meters, and the power rating is up to 4.55MW.
Various features are provided to ensure the easy maintenance and to improve maintenance efficiency of the Wind Turbines.
Components are sealed to prevent sand and dust build-up within the equipment.
Quicker response, more accurate pitch control, better pitch capability in emergency
High power radiator and converter are designed to operate in the high altitudes condition.
When the grid voltage or frequency fluctuates, it meets the requirements of active power, reactive power, frequency, and inertia response.
