1. 12m Free Standing Tower1.2 Tower Material and Design Characteristics

Tower material: Hot galvanized iron with Fluor-Carbon Painting.

Design Characteristics: Tubular design of top

section of the tower can reduce tower shadoweffect.

Tubular design with eight sides of the two lowersections of the tower can ensure the strength of thetower.



2. GeneratorGearless and NdFeB permanent-magnet three phases generator

(weight: 68 kg)



2. Generator2.1 Bearing-type and brand

SKF-6208, made in Sweden.



2. Generator2.2 Main shaft of the generator

It is made in two kinds of steel. Inner part is made of carbon steel which canensure the high machining precision of the shaft. Outer part is made ofstainless steel which has a strongly corrosion resistance. The two kinds ofsteel are joined by Friction Welding.

2.3 Nacelle of the generator

Combined with aeronautical coating technology,it is made of A360 anticorrosive aluminum alloythrough vacuum casting processed by a 900 tonsmold.



3. Blades and Hub3.1 Blades material

Outer layer is made of GFRP (Glass Fiber Reinforced Plastics) and carbonfiber; inner part is filled with an insert and Epoxy Vinyl Ester Resin whichcan ensure the strength of the blades and also reduce the weight of the

blades, each blade is 7.8 kg.

insert



3. Blades and Hub3.2 Blades Design Characteristics

Efficient aero-dynamic design: start-up wind speed-1.8m/s,survival wind speed-60m/s, TSR value-8, Cp value-about 0.43.

◆ The design of wing shape meets U.S. NACA2412 standard.◆ Round blade root; tick mark on the blade root; adjustable blade angles to

achieve maximum efficiency.



3. Blades and Hub3.3 Hub

It is made of steel by precision forging but not casting.The strength of the hub processed by precision forging istwice as much as that processed by casting.



4. Braking SystemThe wind turbine has two braking systems, short circuit

braking system and electromagnetic brakingsystem which can ensure the wind turbine can stop turning athigh wind speed.

6.6 Airforce 4.1-5 KW three phases grid-tied system

In some islands or villages where are abundant wind resources but common solar resources, because of the small capacity oflocal public grid (for example, small three phases(380V/400V)grid), it needs three phases grid-tied wind turbine systems to

balance such a limited local grid.
