The production of 2.5 MW wind power tower of the fourth bureau of Sinohydro was completed

Recently, with the last set of towers of the 2.
5 MW model tower of the 200 MW wind power project in Hami Santanghu (3B) undertaken by Xinjiang Henghe Company of the Fourth Bureau of Sinohydro, the project was successfully delivered, marking the full completion
of the supply task of the project.

The project is located in Santanghu Township, Balikun, Hami City, Xinjiang, with flat terrain, an altitude of 1100 to 1380 meters, and the west side of the wind farm is close to the provincial highway S326, with convenient
transportation.
The wind farm tower is a 2.
5 MW series model designed by Goldwind, and Henghe Company undertakes the manufacture and supply
of 20 of them.

The tower is composed of two straight and two cones in the upper, upper, middle and lower sections, with a maximum pipe diameter of 4.
3 meters and a total height of 87.
25 meters
.
The weight of a single tower is more than 258 tons, and the total engineering volume is more than 5100 tons
.

This project is the first 2.
5 MW wind power project undertaken by Henghe Company, in this regard, Henghe Company has formulated a special production plan for high-power towers according to its own conditions, and in terms of production process, it has been adjusted from conventional whole section pair and whole section welding to section group pair and section welding; In terms of lifting, since the weight and length of the tower section cannot be reversed by one or two door machines, the conventional door machine with reverse operation is changed to the door machine and car crane with reverse operation; In terms of technology, before the formal production, the technical personnel used the three-dimensional drawing software to simulate the assembly demonstration on the computer, determine the technical difficulties that are easy to occur in the production process in advance, and formulate the corresponding preventive measures and plans in advance, which greatly avoids the problems of technology, quality and production organization in the production process
.

At the same time, for the more complex detachable parts assembled in the wind farm, pre-assembled in the field is carried out before delivery, so as to avoid quality problems such as the detachable parts cannot be assembled or missing parts in the wind farm; In terms of transportation, Henghe Company also undertook the high-power tower transportation task for the first time, and through the company's careful arrangement and deployment, no safety and quality accidents occurred during the overall transportation of the project; In terms of after-sales service, in the process of hoisting, in addition to arranging after-sales service personnel, Henghe Company also arranged technicians to track and provide technical guidance to the first hoisting, and successfully completed the first hoisting without finding any technical and quality problems
.

The successful completion of the 2.
5 MW tower project indicates that Henghe has a relatively mature high-power tower technology and production organization capabilities, and lays the technical and production experience foundation
for the post-production of 3.
0 MW tower and larger MW model.
