Features of Tension Towers

High-Strength Load-Bearing Structure

Constructed from Q355/Q420 steel, these Tension Towers possess exceptional load-bearing capacity, making them ideally suited for high-stress transmission lines at corner and terminal points.

Standardized Structural Design

Designed based on a unified structural model applicable to 35kV–1000kV lines, this approach reduces the complexity of engineering calculations and enhances the efficiency of coordination between design and construction phases.

Modular Assembly Structure

Utilizing a bolted, segmented assembly method, the structure facilitates ease of transport and on-site installation, resulting in an approximate 30% increase in construction efficiency.

Adaptability to Complex Routes

Suitable for transmission lines traversing mountainous terrain, river crossings, and long-distance routes; the design supports adjustments for line angle changes and variations in elevation.

Quality Control

Raw Material Incoming Inspection
Upon arrival at the facility, all steel materials (Q235/Q355/Q420) undergo testing for chemical composition and mechanical properties to ensure that their yield strength aligns with the specifications in the design drawings.

Steel Cutting Precision Inspection
Following CNC cutting, the dimensions of each individual piece are cross-checked; for critical structural components, deviations in length and bolt hole positioning are strictly controlled within a tolerance of ±0.2 mm.

Component Processing Inspection
Segmented inspections are conducted during the drilling, bending, and welding stages to ensure that there are no structural deviations at the load-bearing connection nodes.

Weld Quality Inspection
Critical welded joints undergo a dual inspection process—combining ultrasonic testing with visual examination—to verify that weld continuity and load-bearing strength fully comply with design standards.

Hot-Dip Galvanizing Inspection
Upon completion of the hot-dip galvanizing process, the thickness of the zinc coating is measured and controlled within the range of 85–100 μm, ensuring uniform anti-corrosion coverage with no uncoated spots.

Component Pre-Assembly Inspection
Prior to shipment, a trial assembly is performed to verify the alignment of bolt holes, as well as the overall structural verticality and load-bearing consistency.

Finished Structure Verification
The finished structure undergoes a comprehensive verification against the design drawings to confirm that the tower configuration, dimensions, and load-bearing parameters all fully meet the engineering design requirements.

Pre-Packaging Protection Inspection
Before packaging, the galvanized coating and component surfaces are inspected, followed by the application of anti-rust treatments and protective measures to safeguard the materials during transit.
