Galvanized tension tower is a core loadbearing structure for highvoltage overhead transmission lines, specially engineered to sustain large conductor tension, bear angle turning and terminal pulling force for 35kV500kV power grids. Adopting Q355 highstrength steel and full hotdip galvanizing complying with ASTM A123 & ISO 1461, the minimum zinc coating reaches 86 μm, delivering outstanding anticorrosion performance for coastal, highaltitude and desert scenarios with over 50year service life.
Our factory owns complete in-house production lines with annual output up to 70,000 tons, supporting customized
lattice or tubular structures per client drawings. Products pass SGS third-party mechanical load-testing and obtain
ISO9001, EN 1090-1 CE certification, with full MTC test reports supplied for each batch. We have successfully
delivered multiple overseas power projects covering Latin America, Central Asia and Southeast Asia. Modular
components enable fast on-site assembly and low later-stage maintenance. Recommended for line corner sections,
terminal positions and crossing zones under complex geological and meteorological conditions.
Application Scenarios Galvanized Tension Tower
Galvanized tension tower is a critical infrastructure component for overhead power transmission systems,
purpose-built to withstand heavy conductor tension, unbalanced pulling force and wind-ice loads. It is widely
deployed across multiple power-grid scenarios for 35kV-500kV transmission projects.
First, it serves line corner sections, where the transmission line changes direction. The tower absorbs lateral pull
from power conductors and stabilizes the whole line route. Second, it applies to terminal end positions, connecting
overhead lines with substations; it bears full tension of incoming conductors to avoid force damage to substation
equipment. Third, it fits crossing zones, spanning highways, rivers, railways and farmlands. Its robust structure
prevents line sag or breakage under harsh weather.
Besides normal land areas, the hot-dip galvanized anti-corrosion feature makes it ideal for harsh environments:
coastal salt-fog regions, high-altitude wind-prone zones, arid desert areas and heavy-icing mountain districts.
Backed by our EN 1090-1 CE, ISO9001 certifications, SGS load test reports, 70,000-ton annual production capacity and
proven overseas project references, customized tubular or lattice-type tension towers can be supplied to match local
geological and meteorological conditions. Modular design ensures quick field installation and low long-term
maintenance input.
Standard Routine Maintenance Guidelines for Galvanized Tension Tower
1. Visual External Inspection (Routine cycle: every 6-12 months; quarterly inspection for coastal, heavy-salt-fog
and heavy-ice areas)
Check the hot-dip galvanized surface for zinc peeling, rust spots, scratch damage and paint loss. Record corrosion
positions and scope. Inspect tower body, cross-arms and connection plates for deformation, cracks or bending caused
by wind, ice or collision. Verify no bird nests, foreign attachments or accumulated debris on tower components.
2. Fastener & Connection Check
Examine all bolts, nuts and lock washers. Retighten loose fasteners; replace missing, cracked or heavily-rusted
hardware. Confirm torque values comply with design and EN 1090 requirements. Check splice joints of lattice or
tubular sections for displacement and gap abnormality.
3. Foundation and Anchor Inspection
Survey tower foundation for cracks, settlement, soil erosion and water accumulation. Check anchor bolts for corrosion
and exposure. Reinforce surrounding soil if slope slippage risk appears.
4. Repair Requirements
Small-area galvanizing scratches and rust shall be repaired with qualified zinc-rich coating. Large-area corrosion or
structural deformation requires professional load assessment before component replacement. Never weld on-site
without technical approval, as high temperature will destroy original galvanized layer.
5. Document & Risk Management
Keep complete maintenance records including inspection date, defect photos, repair measures and test reference data.
For towers in severe-environment overseas projects, combine SGS inspection baseline data to compare corrosion change
trend. Stop nearby construction activities that may cause tower collision or foundation damage.

FAQ about Galvanized Tension Tower
Q1: What is the main function of a galvanized tension tower?
A: It is a key transmission tower for 35kV-500kV power lines. Primarily designed to withstand large conductor
tension, unbalanced pulling force, wind and ice loads. It is used for line corners, terminal ends and river/highway
crossing sections to stabilize the whole overhead transmission route.
Q2: How long is the service life of hot-dip galvanized tension tower?
A: With Q355 steel and full hot-dip galvanizing following ASTM A123 and ISO 1461 (minimum 86 μm zinc coating), normal
service life can reach over 50 years. Service life will be affected in coastal salt-fog, heavy-ice and highly
corrosive areas, requiring shortened inspection cycles.
Q3: What certifications and test reports can you provide?
A: Our products hold ISO9001 quality management certification and EN 1090-1 CE certification. SGS third-party
mechanical load test reports and MTC material test certificates are available for each production batch.
Q4: Can you supply custom-designed tension towers?
A: Yes. We support both lattice-type and tubular-type solutions. Customers may provide drawings, voltage level,
wind-ice load parameters and site geological conditions for custom fabrication. Our annual production capacity
reaches 70,000 tons to handle large-volume overseas project orders.
Q5: What are common maintenance requirements?
A: Routine inspection every 6-12 months (quarterly for harsh environments). Check galvanized surface corrosion, bolt
torque, structural deformation and foundation condition. Small rust spots use zinc-rich coating for repair; on-site
welding is forbidden as it damages galvanized protection.
Q6: What project environments are suitable for this tower?
A: Applicable for ordinary land, coastal salt-fog zones, high-altitude windy regions, desert and mountain heavy-ice
areas. We have completed multiple power-grid projects across Latin America, Central Asia and Southeast Asia.
