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 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.

TESTS
X.Y. Tower has a very strict test protocol to ensure all products we fabricate is quality. The following process is applied in our production flow.
Sections and Plates
1. Chemical composition (Ladle Analysis)
2. Tensile Tests
3. Bend Tests
Nuts and Bolts
1. Proof Load test
2. Ultimate Tensile Strength test
3. Ultimate tensile strength test under eccentric load
4. Cold bend test
5. Hardness test
6. Galvanizing test
All the test data are recorded and will be reported to the management. If any flaws are found, the product will be repaired or scraped directly.
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.
Free prototype tower assembly service
prototype tower assembly is a very traditional but effective way to inspect whether the detail drawing is correct.
In some cases, clients still want to do prototype tower assembly to ensure the detail drawing and fabrication is OK. Hence, we still provide prototype tower assembly service for free to customers.
In prototype tower assembly service, X.Y. Tower makes commitment:
• For each member, the length, position of holes and interface with other members will be checked accurately for proper fitness;
• Quantity of each member and bolts will be carefully checked from the bill of materials when assembling the prototype;
• Drawings and bill of materials, sizes of bolts, fillers etc. will be revised if any mistake is found.
Customer visit service
We are so glad that our clients to visit our factory and inspect the product. It is a great chance for both sides to know each other better and strengthen cooperation.For our clients, we will receive you at Airport and provide 2-3 days accommodation.
Package and shipment
Every piece of our products is coded according to the detail drawing. Every code will be put a steel seal on each piece. According to the code, clients will clearly know a single piece belong to which type and segments.
All the pieces are properly numbered and packaged through the drawing which could guarantee no single piece missing and easily to be installed.
Shipment
Normally, the product will ready in 20 working days after deposit. Then the product will take 5-7 working days to arrive at Shanghai Port.
For some countries or regions, like Central Asia, Myanmar, Vietnam etc., China-Europe freight train and carriage by land may be two better options of transportation.
