Endurance Wind Power offers the Endurance E-3120 - 50 kW Wind Turbine. The E-3120 model is meant for manufacturing and fabrication companies requiring 125,000–250,000 kWh of electricity per year.
This downwind type of wind turbine has three blades and a horizontal axis. The rotor diameter of this wind turbine is 19.2 m, its fiberglass/epoxy made blades length is 9 m and the swept area of this turbine is 290 m2. This grid connected wind turbine has a rated power output of 55 kW at 11 m/s speed. The rotor speed of this wind turbine is 42 rpm. The cut-in wind speed of this wind turbine is 3.5 m/s and its cut-out wind speed is 25 m/s and this wind turbine can withstand a wind speed up to 52 m/s.
The Endurance E-3120 provided by the Endurance Wind Power has an induction type generator with a 3Ö, 480 VAC or 600 VAC @ 60 Hz 3Ö, 400 VAC @ 50 Hz configuration and optional single phase generators are also available. This wind turbine model is available in two types of towers such as free-standing monopole and free-standing lattice in 30.5, 36.5 and 42.7 m heights. The E-3120 model has a PLC type of control system connected utilizing a wireless or wired networked software interface with facility to monitor and control from remote.
The Endurance E-3120 model has safety features such as swift fail-safe dual mechanical brakes as its main braking system, a pitch control system utilizing passive spring loaded mechanism as additional safety. The automatic emergency control system closes the functioning of wind mill during high wind speed, grid failure, over speeding of the turbine and during all types of failure conditions.
