System application:
On grid system wiring diagram
2.3.5kw Centrifugal pitch wind turbine introduce
Wind speed control blades angle changing. The blades angle twists according to the wind speed, this
will change the blades itself aerodynamic characteristic to control wind turbine rotation speed. This will
make the generator output power constantly.

Output power curve
variable pitch wind turbine 3.5kw features
Blades rotor: Blades rotor efficiency can reach 0.42. Noise level is less than 65db, and balance
adjustment
has been carried out strictly before leaving factory.
Generator: Blades rotor drives directly. Lower rotation speed, PMG synchronous generator, over load
capacity is 150%.
Pitch controlled wind turbine: Adopt stable pitch controlled system, can be used in variable environments
Low failure rate
Speed regulates Performance: The precision of pitch controlled system is 10 r/min, and never over speed
at gale.
Low Start up Wind Speed: According to different wind conditions, adjust the blade initial angle to make wind turbine
start up at low wind speed.
The start-up wind speed is ≤3m/s.
Manual brake: Reliable braking system, easy to operate, can stop wind turbine at any time.
Automatically undo cable: slip rings undo the cable automatically. Ensure the cable has not twist. Double
carbon brushes structure make sure power transfer without failure.
Well-adapted Wind turbine: The operation wind speed is 3-30m/s.

We started to manufacture wind turbine in 1994. In 2004, there are only 4 small wind turbine manufactures
in China. We keep improving and develop in the small wind turbine field. We are not the leading small wind
turbine exporter, but we are the leading wind turbine manufacture and designer now.
We manufacture 300w-30kw fixed pitch wind turbine;
2kw, 3kw, 5kw, 10kw, 20kw, 30kw, 50kw, 60kw pitch controlled wind turbine;
1kw, 2kw, 3kw, 5kw Vertical axis wind turbine;
On grid system/off grid system, wind solar hybrid system; Water heating system;
For more details, pls contact with us via e-mail.
Certification
Workshop, office and stock
1. Wind turbine model selection
It depends your local annual average wind speed, daily/monthly home power consumption.
Low average wind speed place, select larger blades rotor, higher rated working voltage;
Rich wind place select speed limited wind turbine: variable pitch wind turbine, stall out vertical axis wind
turbine.
The safety and steady working system is the first choice.
2. Wind turbine tower selection
Now we have guy wire tower, stand alone tower, tilting up tower, hydraulic tower.
Guy wire tower cost is lower, easy to delivery. But the installation area is larger;
Tilting up tower is for 500w-5kw wind turbine. Easy installation, small installation area. But the delivery cost is higher.
Hydraulic tower: It is used for no crane place. Easy installation and put down. The cost is higher.
Stand alone tower for the installation place with crane.
The tower height: Make sure blades rotor is higher than wind turbine surrounding barrier height.
3. Working system selection
On grid system: wind turbine with tower + PWM controller with dump load + grid tie inverter;
Off grid system: wind turbine with tower + PWM charge controller with dump load + battery group + inverter;
Wind solar hybrid on/off grid system: Safety and reliable than only wind or solar system.
Wind turbine water heating system: work in rich wind place. Average wind speed higher than 8m/s.
For more question, pls contact with us directly. We will give you a professional response.
Why select us:
We are the wind turbine designer and manufacture. We know our wind turbine advantage and disadvantage
in different wind condition.
I have more than 10 years wind turbine sales experience. We provide the right wind turbine and working
system to different user according to their different situation and request.
In 2004, there are 4 small wind turbine manufacture. Now there are so much trading company and
manufacture, we know Chinese small wind turbine market well and can provide user more useful advise.
