Windtec, a subsidiary of American Semiconductor Corporation, provides wind turbine designs to the wind turbine manufacturers. The WT1650df wind turbine design features a three-phase, double fed induction generator. The wind turbine design is a 1.65 mega watt model that uses pitch system design. The wind turbine model is available for 50 or 60Hz, and for hot or cold climate application.
The hub height options available with the WT1650df wind turbine are 65, 70 and 80 meters. The hub height depends on the type class. The wind turbine model features a pitch mechanism that adjusts the angle of blades smoothly and quickly when the wind speed crosses the limit. The wind turbine also features an integrated safety lock system that allows blades turning into feathering position, in case of overall pitch drive fault.
The mainframe of the WT1650df wind turbine is welded, while the rigid hub is made of cast iron and blades are made of epoxy glass fibre. The wind turbine design, available from Windtec, features a conical tubular steel tower construction. The cut-in wind speed of the wind turbine is 3.5 meters per second. This wind turbine design features slide type of yaw bearing with four gear motor drive units. The WT1650df wind turbine has individual blade pitching for operational brake and disc brake for mechanical brake.
