Tower description
Transmission tower is a tall structure, usually a steel lattice tower, use to support an overhead power line. We render these products with the help of
diligent workforce having vast experience in this field. We go through detailed line survey, route maps, spotting of towers, chart structure and technique document while providing these products.
Our product covers the 11kV to 500kV high voltage tower,while include different tower type for example suspension tower, strain tower, angle tower, end tower etc.
Additionally, we still have a vast designed tower type and design service to be offered while if clients have no drawings.

Brief introduction of Tower production process and technology.
1. Lofting
Computers are used to stake out in X.Y. Tower. Three-dimensional steel structure computer-aided design TMA software is adopted. The program has the characteristics of high accuracy, strong applicability, and intuitiveness. Using this technology can improve work efficiency and ensure lofting accuracy. According to the structural characteristics of iron attachments, our company has compiled the geometric size check program and drawing program of iron attachments. The program has the characteristics of high accuracy, strong applicability, and intuitiveness. Using this technology can not only improve work efficiency, but also ensure the accuracy of drawing.
2. Cut off
X.Y.Tower adopts large-scale plate cutting equipment, section steel cutting equipment and advanced automatic flame cutting equipment, which is fully capable of ensuring that the quality of steel cutting meets the requirements of national standards and relevant technical documents.
3. Bending
X.Y.Tower uses large-scale hydraulic equipment and self-developed professional bending molds for bending to ensure that the processing accuracy meets the requirements of the GB2694-81 standard and the tender technical documents.
4. Hole making
X.Y.Tower has the domestic advanced level CNC angle steel reduction automatic processing line and other professional stamping equipment and drilling equipment, and is fully capable of ensuring that the quality of the holes meets the standards and user requirements.
5. Cut corners
The angle cutting equipment developed by our company can cut various forms of angle steel, and can fully guarantee the accuracy of angle cutting.
6. Clean roots, shovel back, plan bevel
X.Y.Tower has domestic advanced level of planing equipment, especially the high-speed planer with a stroke of 3 meters, which is most suitable for processing large iron accessories for root removal, shoveling, and beveling workpieces. The processing accuracy can fully meet the relevant standards and Provisions of technical documents.
7. Welding
X.Y.Tower adopts the domestic advanced level of carbon dioxide gas shielded welding machine, and has technicians with welding qualification certificate to operate it to ensure the welding quality. In order to ensure the geometric dimensions of the welded parts, our company will use molds for butt welding. In order to ensure the stability of the welding, our company will use professional drying equipment and heat preservation equipment to dry and store the welding rod. Therefore, it is fully capable of ensuring that the welding quality meets the relevant standards.
