The core components of the world's largest wind turbine rotor were successfully
developed in Dalian.
It is reported that the product is cast
by Dalian Heavy Industry.
It is a product of GE General Electric for the offshore EDF project built by Alstom of France, and it is also the largest wind turbine product currently put into commercial operation in the world
.
With a diameter of 6.
9 meters and a weight of 40 tons, the wind turbine rotor is the most difficult to machine in the casting field of thin-walled, large-scale rotating products
.
Not only is no structural defect required, but the center offset cannot exceed 15 microns
in the 6.
9 m diameter range.
This product has been trial-produced in many factories in Italy, France and other factories, but it was not successful
due to casting defects.
After more than 4 months of hard work, Dalian Heavy Industry successfully developed the product, and thus became the exclusive supplier
of this key component of GE's 6 MW offshore wind power project in the United States.
