There are three main types of onshore wind tower technologies:
Gao Rou Tower. Mixed Tower.
Truss lattice towers.
1. High flexible tower technology
Representative manufacturers include: Goldwind 185m flexible tower technology and Yunda 153m flexible tower technology.
Goldwind: Split steel tower
The bottom diameter is increased to 6m+, and the large diameter section is divided into 3 pieces longitudinally. There are 7 sections in total, the lower 4 sections are sliced structures, and the upper 3 sections are traditional cylindrical structures.
Reach 153m tower technology
The tower active damping technology is used to quickly cross the resonance speed.
Second, the mixing tower technology
The structure of the mixed tower is diversified, and the mainstream adopts two-half type and four-part typeThe production of concrete section tower tends to be standardized, and the size of the segment tends to be miniaturizedAt present, the mainstream manufacturers in the industry have mixed tower fan products.
Square rounded mixed tower [sea installation].
Octagonal mixed tower [Harbin Electric].
Sectional jacking of the self-lifting mixed tower [Xu Ji].
3. Prestressed lattice steel pipe tower technology
The lattice truss tower components are small in size, which is easy to transport and installThe bottom space is large, but the actual land acquisition area is small, which has good ecological friendliness.
Fourth, summary. 3 different technologies, at present, the mixed tower technology is more favored, the technical route is blooming, and the whole industry chain is relatively matureNew tower technology (lattice steel tube towers) is developing rapidly.
