Composite Technology Corporation provides DeWind wind turbines. The DeWind D8 wind turbine generates maximum power of 2,000 kilowatts at voltage and current of 690 volts and 1675 amperes respectively. The wind turbine consists of a doubly fed generator and an IGBT inverter. The main braking system of the DeWind D8 wind turbine is a central blade pitching unit and is hydraulic, while the emergency braking system is a single blade pitching unit.
The wind turbine from Composite Technology Corporation comprises sensors that facilitate monitoring of wind direction, ambient temperature and wind velocity. The remote monitoring option available in the DeWind D8 wind turbine enables automatic data transfer.
The DeWind D8 wind turbine has a three stage planetary spurwheel gearbox with the transmission ratio of 1:94.4. The yaw system consists of four electric geared drives. The wind turbine has a nominal rotational speed of 18 rotations per feet. The cut-in and cut-out wind speed of the wind turbine from Composite Technology Corporation are 3 meters per second and 25 meters per second.
The DeWind D8 wind turbine operates at the nominal wind speed of 13.5 meters per second and has survival wind speed of 57.4 meters per second. It has three blades made from either GFRP or CFRP material. These blades have a swept area of 5,027 square meters. The lightning protection feature of this wind turbine from Composite Technology Corporation is a metal receptor on the wing tip and a copper mesh. The rotor of the DeWind D8 wind turbine has a diameter of 80 meters.
