Transmission Line Towers
Spatial truss construction and several visible forms allow the tower configuration to follow route function and line arrangement.
Transmission line towers are steel lattice support structures selected based on their specific locations along overhead transmission lines. Tangent towers are used for standard line sections, while tension, angle, terminal, transposition, and crossing towers serve various functional requirements. Common configurations include "wine-glass," "cat-head," "upper-character" (inverted-L), "stem-character" (T-shaped), and barrel-type arrangements. Based on a spatial truss design, these structures are assembled from angle steel members and connection plates; joints utilize rough bolts to transfer shear forces, and the segmented construction facilitates transport and installation.These Transmission line towers ensure that necessary safety clearances are maintained between conductors and ground wires, as well as between these lines and the ground or surrounding structures; notably, functional requirements and tower type selection are distinct considerations.

Product Advantages
• The open spatial truss organizes the supporting members into a clear lattice framework for the overhead route.
• Single equal-angle and combined-angle choices provide two defined member arrangements for the tower body.
• Connection plates gather adjoining members at each node, while coarse bolts create the sectional joints.
• Welded tower-foot components and bolted upper sections keep the two construction methods assigned to different parts.
• Sectional bolted construction supports transport before the members are erected into the complete tower.
• Transmission Line Towers use Q235 or O345 steel with hot-dip galvanizing and conditional climbing access below 60m.
Our Services
The company supplies and installs towers and also undertakes tower maintenance. Product coverage extends beyond power towers to communication, monitoring, observation, lightning-protection, training, rooftop decorative, process, meteorological, television, monopole, and landscape structures. This broad service scope supports projects that require coordination between fabrication, section identification, site assembly, and later maintenance.
FAQ
Q: Which members form the tower framework?
A: Single equal-angle or combined-angle steel members form the spatial truss, while connection plates and coarse bolts organize the structural nodes.
Q: How are the tower-foot and upper framework assembled?
A: Several steel plates may be welded into a combined tower-foot component, while the remaining sectional framework uses bolted construction.
Q: Which material, finish, and access conditions apply?
A: The structure uses Q235 or O345 steel with hot-dip galvanizing, and climbing pegs may be fitted to one principal member below 60m.
