Transmission Line Towers
Voltage Grade: 35kv-750kv
Wind Speed: 0--330KM/H
Transmission Line Towers are core steel structural facilities that support overhead transmission line conductors and lightning conductors. They are designed with spatial trusses to withstand external forces such as conductor tension, wind loads, and icing, ensuring safe and efficient transmission of electrical energy.

advantage
High strength and lightweight design
- Galvanized angle steel (Q235/Q345 steel) or steel pipe bolts are used to connect the lattice space truss, with a compressive strength greater than 350MPa.
- The open structure reduces wind resistance (compared to solid towers) and can withstand typhoons of level 17 (verified by the wind tunnel of Tsinghua Hefei Institute).
- Modular prefabricated components reduce steel consumption by 30% and optimize the footprint of tower bases (such as 14m x 14m for 500kV tower bases).
Excellent disaster resistance capability
- Seismic resistance: The dual stage spring damping system controls the displacement of the sixth level earthquake to be ≤ 3.2mm.
- Ice resistance: The Xuefengshan test base verifies the ± 1600kV level ice bearing capacity.
- Anti corrosion: The overall hot-dip galvanizing (zinc layer ≥ 85 μ m) has a service life of over 30 years and is suitable for high corrosion environments along the coast.
Multi scenario adaptability
- Full voltage coverage: support 10kV power distribution to ± 800kV UHV (such as Xizang 4797m high altitude tower).
- Terrain compatibility: For complex terrains such as mountainous areas and river crossings, a cable-stayed V-shaped tower can be used (saving 40% of steel), while a double loop drum tower can be used in plain areas (reducing corridor width by 30%).
Land and cost savings
- The dual circuit design (six phase conductor) reduces the demolition area compared to a single circuit (such as saving 5144m ² in the Zhejiang project).
- Factory prefabrication+on-site bolt assembly increases construction efficiency by 40%
