The three largest manufacturers of wind turbine blades in the world

The three largest manufacturers of wind blades in the world are Denmark's LM Company, Vestas Wind Systems and Germany's Enercon.

In 2001, Denmark's LM Company invested in and established a wholly-owned enterprise in Tianjin that specializes in the production of wind turbine blades - Elm Glass Fiber Products (Tianjin) Co., Ltd., as China's first multinational blade manufacturing factory . With the intensive development and actual demand of China's wind energy market in the past two years, LM has made additional investment in the Tianjin factory. With an initial investment of US$7 million and an additional investment of US$18 million, the blade specification has been adjusted from the original maximum length of 34 meters to 37 meters, which will be mainly used for the assembly of China's future mainstream 1.5-megawatt wind turbines.

The Danish Vestas Group, the world's number one in the field of wind power equipment, officially established a wind turbine blade production plant in Tianjin TEDA Development Zone after investigating several candidate locations. The plant has an investment of approximately US$30 million and produces V80 2-MW wind turbine blades with a length of 39 meters.

Enercon is a German complete wind turbine manufacturer. It manufactures a large wind turbine E-112 with a capacity of 4.5 MW, a blade length of 54 meters and a weight of 20 tons. Currently, the company also intends to enter the Chinese wind turbine and blade market. In addition, the Spanish company GAMESA is also an internationally renowned manufacturer of wind power equipment and blades. It has also decided to set up a factory in China, including blade manufacturing.

Fan principle, however, in order to have a certain strength, the closer to the root of the fan blade, the thicker it becomes. Made of fiberglass. The reinforcing ribs made of fiberglass are placed in the mold and then injected with resin to form. The small air leaf has a solid structure, and the large one has a hollow structure. The hollow part of the large fan blade is almost half a cylinder. It is not an exaggeration to say that it is based on the principle of an airfoil. The installation angle of the fan blades is generally adjustable. The wind turbine has a complete constant speed device, and a device that automatically brakes, then turns, and finally rotates again when the wind direction changes. Don't do your own research and development. If you want to make a finished product for sale, just buy one and then reverse engineer it. You can search for "Manufacturing Process of FRP Fan Blades".
