Technological Breakthroughs and Application Prospects of Steel‑Structure Truss Towers for Wind Power
As wind power advances toward taller towers, larger capacities, and lower-wind-speed regions, conventional conical tower designs are encountering transportation and cost constraints, while pure steel truss tower technology has achieved a major breakthrough.

I. Technological Innovations
Upright truss structure: all-steel trusses, vertically aligned, with modular components.
Node Optimization: Primarily based on bolted connections, with factory prefabrication and rapid on-site assembly.
Lightweight design: 20%–30% lighter than conical barrels of the same height, with a significant reduction in steel consumption.
Transportation Advantages: Component miniaturization overcomes transportation constraints in mountainous and remote areas.
II. Core Advantages
1. Compact design: The tower has a small footprint, saving land and having no impact on agriculture or animal husbandry.
2. Efficient installation: modular lifting reduces the construction period by 40%.
3. Cost Reduction: Comprehensive costs for materials, transportation, and construction have decreased by 15%–25%.
4. Operations‑friendly: open architecture, excellent ventilation, and easy corrosion‑resistant maintenance.
III. Application Prospects
Wind farms in low-wind-speed areas, mountainous regions, coastal zones, and remote locations.
150–250m ultra-high tower project.
Suitable for large-capacity wind turbines of 8 MW and above.
The nation’s first 160-meter-tall, 8.35 MW all-steel truss tower has been successfully hoisted into place, marking a new stage in China’s wind‑power steel‑structure technology—characterized by diversification and enhanced efficiency.
