Heavy Duty Tension Tower

The Heavy Duty Tension Tower is a self-supporting steel lattice tower used in 110kV–800kV transmission lines, installed at tension, terminal, and angle sections to carry conductor tension and unbalanced loads from conductor breakage.

Large-section angle steel members increase longitudinal tension capacity for large conductors and long-span transmission lines
Dual-sided strain attachment points anchor conductor tension and withstand unbalanced loads caused by conductor breakage
Reinforced shear connection plates reduce cracking risk at primary structural joints under long-term tensile loading
Enhanced uplift-resistant tower legs improve foundation capacity for large-angle and heavy-load conditions
86 μm hot-dip galvanized coating provides long-term atmospheric corrosion protection

Assembly Accuracy Verification
Segmental trial assembly is conducted before shipment to verify hole alignment and assembly accuracy.
International Standards
Manufactured under ISO 9001 with fabrication compliant with EN 1090 and AWS D1.1.
Quality Documentation
MTR, galvanizing reports, UT/MT reports, and trial assembly records included.

Nested Packing System
Members are nested by size, protected with rubber edge guards, and secured on fumigation-free pallets.
Stamped Identification
Each component is uniquely stamped and packed according to installation sequence.
Transport Protection
Internal bracing and securing applied for ocean and land transport stability.
