Ningjin huaya industry Co., Ltd. is specialized manufacture of small wind turbine generator.
Form the first 50W, 100W wind turbine to 300W-20kw wind turbine, we past 15 years. Now we have the steady off-grid working system, 1kw, 2kw, 3kw, 5kw, 10kw, 20kw on-grid working system. To provide the steady system is our aim.
Blades:
The blade form is chosen by wind tunnel test. The aerofoil with the highest wind speed utilization ratio is used. The wind energy transfer efficiency can reach 0.42.
Generator:
ND-fe-b permanent magnet. Packaged type tangential grinder magnetic circuit rotor; High magnetic flux density, small cubage, good manufacturing technics and high capability.
Adopt Sweden SKF bearing.
Close transmission slip ring, the cable will not enlace
Tower:
Tower with guy wires, tilting up tower, hydraulic tower, independence tower. It can be designed according to your request.
Now the wind turbine system is working in more than 30 countries. To provide the good, steady system is our aim.
