[0090] By providing the reinforcing cable 50, it is helpful to ensure the connection strength between the first connecting component 20 and the second connecting component 31 and the cylinder body 10. In addition, the reinforcing cable 50 can also increase the prestress to improve the stress of the weld, thereby ensuring the strength of the tower transition section 100, and further ensuring the safety performance of the tower 1 used in the tower transition section 100.

[0091] Exemplarily, when the first connection assembly 20 includes two first connection members 21, the reinforcing cable 50 is connected between the annular bodies 211 of the two first connection members 21. Of course, when the first connection assembly 20 includes multiple first connection members 21, the reinforcing cable 50 passes through the annular body 211 of each first connection member 21 in sequence along the axial direction Y to be connected thereto.

[0104] Since the tower adapter section 100 provided in the embodiment of the present application can reduce weight, facilitate transportation, and help reduce costs, the tower 1 including the tower adapter section 100 is conducive to reducing weight and costs.

[0105] Optionally, the tower 1 may further include a tower section connected to a side of the tower body 10 away from the tower body 200 along the axial direction Y, that is, the tower 1 includes a tower section, a tower transition section 100 and a tower body 200 connected in sequence from top to bottom.

[0106] Optionally, the tower 1 may be a lattice tower, the tower body 200 may be a lattice structure, the tower body 200 may include a plurality of support columns, and connecting beams may be connected between the plurality of support columns.

[0107] Exemplarily, the number of support columns is four, and the number of second connecting members 31 is correspondingly set to four. The central axis of the support column extends downward and outward, that is, the central axis of the support column intersects with the axial Y axis, so that the maximum dimension of the tower body 200 in the horizontal direction increases successively from top to bottom.

[0108] The embodiment of the present application further provides a wind turbine generator set, comprising the tower 1 provided in the above embodiments.

[0109] Since the tower 1 provided in the embodiment of the present application is conducive to reducing weight and cost, the wind turbine generator set including the tower 1 is conducive to reducing weight and cost.
