Angle Steel Lattice Transposition Tower

As a key truss-type steel tower, Angle Steel Lattice Transposition Tower is mainly assembled from hot-dip galvanized angle steel through high-strength bolts, forming a stable a lattice system with excellent mechanical performance and long service life.

Its core function is to complete conductor transposition in long-distance transmission lines. By reasonably adjusting the relative positions of three-phase conductors, it effectively balances the impedance, capacitance and inductance of the line, reduces unbalanced current, suppresses electromagnetic interference to adjacent communication lines and pipelines, and improves the safety and stability of power transmission.

Compared with ordinary linear towers and tension towers, this type of tower has a more complex layout of cross arms and hanging points, providing sufficient space for jumper transposition to ensure smooth and safe commutation of conductors.

The lattice structure design makes the tower lightweight, high in strength, strong in wind and ice resistance, and adaptable to various complex terrains such as mountains, hills and plains. The all-bolt connection facilitates factory prefabrication, on-site assembly, transportation and later maintenance.

With good corrosion resistance, high structural stability and reliable transposition effect, Angle Steel Lattice Transposition Tower has become an indispensable key equipment in long-distance, large-capacity power transmission projects, effectively guaranteeing the efficiency, energy conservation and stable operation of the power system.

Core Advantages

Professional Transposition

FunctionSpecially designed for three-phase line transposition in high-voltage transmission systems. It effectively balances line impedance, capacitance and inductance, reduces unbalanced current, lowers power loss, and minimizes electromagnetic interference to nearby communication lines, railways and buildings.

Excellent Structural Performance

Adopts lattice truss structure made of angle steel, providing high strength, low wind resistance, strong stability and good resistance to wind, ice and earthquake loads. The structure is lightweight yet rigid, suitable for long-span and complex terrain conditions.

Cost-Effective & Material Efficient

Uses standard hot-dip galvanized angle steel with high material utilization rate, lower steel consumption and project cost compared with full-tubular towers. It offers outstanding performance-to-price ratio for long-distance transmission projects.

Easy Transportation & Construction

Factory-processed components are connected by high-strength bolts. Parts are small in size and light in weight, easy to transport and install on site without on-site welding, greatly improving construction efficiency.

Long Service Life & Low Maintenance

Hot-dip galvanized surface treatment provides strong corrosion resistance, ensuring a service life of more than 30–50 years. Routine inspection and maintenance are convenient, reducing long-term operation cost.

High Adaptability

Suitable for various voltage levels (110kV, 220kV, 330kV, 500kV and above) and terrains including plains, hills, mountainous areas and high-altitude region.
