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.

Fabrication Technologies
All tower parts go through multi-purpose hydraulic machine that can carry out various operations such as shearing, punching and cutting. Hydraulic presses along with matching tools, jigs and fixtures ensure that bent items are handled without distortion. Strategically positioned cranes simplify material handling without any strain on employees. All machines are equipped to process steel conforming to various specifications e.g. ISO, ASTM, JIS, DIN.
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.
Hot-dip galvanizing
Quality of Hot-dip galvanizing is one of our strength, Our CEO Mr. Lee is an expert in this field with reputation in Western-China. Our team has vast experience in HDG process and especially good at handling the tower in high corrosion areas.
Galvanized standard: ISO:1461-2002.
