Features of Overhead Line Tower

High Load-Bearing Capacity
Constructed from Q235 or Q345 structural steel, the Overhead Line Tower is capable of stably supporting the weight of transmission conductors as well as wind loads exceeding 30 m/s, thereby ensuring the long-term safe operation of the transmission line.
Stable Truss Structure
Designed with a triangular or quadrangular truss configuration, the Overhead Line Tower distributes the tension from the conductors across multiple nodes, thereby maintaining the stability of the tower body within long-span transmission lines.


Long-Term Corrosion Resistance
The surface undergoes a hot-dip galvanizing treatment, effectively preventing corrosion caused by rain and atmospheric exposure, and ensuring a service life of over 30 years in outdoor environments.
High Installation Efficiency
Utilizing modular steel structural components, the tower is assembled via bolted connections; this approach minimizes the need for welding operations and significantly reduces on-site construction time.

Quality Control

Raw Material Inspection
Prior to production, all steel materials are inspected for material grade, thickness, and chemical composition to ensure compliance with Q235 or Q345 standards.
Cutting Dimension Verification
After cutting, steel plates and structural steel sections are measured to verify dimensional accuracy, ensuring that all components meet the requirements specified in the design drawings.
Punching Precision Inspection
Upon completion of punching, hole diameters and spacing are inspected to guarantee accurate alignment and connection during component assembly.
Welding Quality Inspection
Welding procedures are executed in strict accordance with the AWS D1.1 standard to ensure uniform and robust weld seams.
Galvanization Quality Inspection
Following hot-dip galvanization, the surface uniformity and adhesion of the coating are inspected to ensure long-term corrosion resistance.
Finished Structure Inspection
Before shipment, the finished structure undergoes a final inspection to verify overall dimensions and component numbering.
