Tubular Steel Tension Tower

All products comply with EN 1090 and EN 10025 European standards, validated by authoritative third-party test reports from SGS and TÜV. Strict raw-material inspection and finished-product quality checks are implemented throughout production to guarantee long-term anti-corrosion performance and mechanical strength. We possess rich global project experience, having supplied tubular steel tension towers for multiple 220kV-500kV overhead transmission projects across Europe, Central Asia and other regions. Optimised for corner-section line transition, wire tension bearing and field installation, this tower features convenient assembly and low maintenance cost. Custom drawing-based processing and full-set certification documents can be provided to match clients' tender and site construction demand.

Application Scenarios of Tubular Steel Tension Tower

Tubular steel tension towers are widely deployed for 220kV-500kV high-voltage overhead transmission lines, ideal for line corner sections, terminal points, river-valley crossings, mountainous terrain and coastal salt-spray zones, as well as power-evacuation projects for wind and solar renewable-energy bases.

Supported by strong in-house manufacturing capacity, our factory completes full-range production workflows: raw-material inspection, CNC cutting, robotic welding, pre-assembly, hot-dip galvanizing and finished-product testing, supporting customised fabrication per client drawings and site-load parameters.

Strict quality assurance covers every production phase. Critical welds adopt non-destructive testing. Products comply with EN 1090, EN 10025 standards, accompanied by authoritative SGS and TÜV third-party test reports covering mechanical strength and anti-corrosion performance.

Proven in multiple overseas transmission projects, these prefabricated towers enable fast field erection and low maintenance, perfectly matching complex-terrain EPC tender and construction requirements

Authoritative Test Data & Reports

Our tubular steel tension tower undergoes comprehensive third-party verification by SGS and TÜV, with full physical-test reports available for project tender submission.Test items cover raw-material mechanical performance, ultrasonic non-destructive welding inspection, hot-dip galvanizing anti-corrosion performance, dimension tolerance and simulated structural load test.

Key authoritative test data

1. Steel substrate: yield strength ≥355 MPa, tensile strength 470-630 MPa, low-temperature impact energy ≥34J at -20 ℃.

2. Hot-dip galvanizing: average zinc-coating thickness ≥86 μm; salt-spray test proves zero red-rust formation over 1000-hour cycle, ensuring long-term outdoor anti-corrosion capability.

3. Weld joint: 100% ultrasonic NDT inspection, no crack or incomplete-fusion defect detected.

4. Structural load: full-scale sample test validates stable performance under design wind speed up to 45 m/s and heavy ice-coating load.

Standard Routine Maintenance Guidelines for Tubular Steel Tension Tower

This guideline covers regular inspection and maintenance for tubular steel tension towers used on 220kV-500kV overhead transmission lines, to secure long-term safe operation.

Visual & structural inspection

Carry out full-site visual inspection every 6-12 months. Check tower body deformation, bolt loosening or missing parts, tube joint connection status, and foundation settlement. Tighten loose bolts to the torque value specified in our factory test documents. Replace damaged components promptly.

Anti-corrosion check

Inspect hot-dip galvanized surfaces. Refer to SGS verified test standard: qualified zinc coating thickness ≥86 μm. Watch for peeling zinc layer, rust spots especially at welding seams and coastal salt-spray zones. Touch-up anti-corrosion paint shall be applied once red rust occurs.

Weld & auxiliary parts check

Examine key weld joints; reference TÜV ultrasonic NDT test standards to spot surface cracks. Inspect insulators, fittings and earthing devices. Ensure earthing resistance stays within design requirement.

Post-extreme-weather maintenance

After strong wind, heavy ice or earthquake, perform special urgent inspection. Check tower deflection and connection integrity. All maintenance records shall be filed for traceability. Our technical team offers after-sales support for complex-site assessment and component replacement.

Advantages of Anbang Tubular Steel Tension Tower

Anbang's tubular steel tension tower delivers comprehensive strengths in structural performance, manufacturing capacity, quality control, certification support and project adaptability for 220kV-500kV high-voltage transmission projects.

In structural performance, round tubular steel design brings higher strength-to-weight ratio. It effectively resists strong wind, ice coating and seismic force, suitable for corners, terminal points, river crossings and coastal salt-spray regions. Hot-dip galvanizing treatment guarantees long-term anti-corrosion performance with expected service life up to 30-50 years.Supported by our full-in-house production line, we implement complete procedures including raw material inspection, CNC cutting, robotic welding and finished-product pre-assembly. Strict quality control runs through every working procedure. Products comply with EN 1090-1 EXC3 and EN 10025-2 standards, backed by CE marking, together with SGS and TÜV third-party test reports covering mechanical property, ultrasonic NDT welding inspection and salt-spray anti-corrosion test.

We support custom fabrication based on client drawings. With rich overseas EPC project experience, we supply complete certification documents, MTR reports and technical after-sales support, simplifying site erection and lowering later-stage maintenance costs.
