Product Description
A wind turbine, which is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home's electrical system.
Our Megawatt wind turbine models from 1MW to 1.5MW, The design experience conceptual design, the system design, the structural design and the analysis, the design appraised that, the experimental simulation, processes and so on prototypical trial manufacturing, obtain a guarantor to post one's bail each step conform to the international standardized design requirement, designs the perfect excellent MW series Wind turbine can supply power for factory, power station, wind turbine farm, offshore wind power project, onshore wind power project etc.
Test and Assembly
1. Before wind turbine leave factory test project.
2. Hydraulic pressure station function experiment
3. Yawing system 500 hours continuous work test
4. Changes the prop pitch system function experiment
5. The transmission system centering tests
6. Transmission system continuous running coordination experiment
7. Master Control logical function test
8. Safety system function test
9. Generating system power control experiment.
