330kV / 400kV Galvanized Steel Single Pipe Transmission Tower
2026-02-24
The galvanized steel single pipe transmission tower is designed to sustain high volt overhead power lines of a modern grid system, 330kV /400kV. This monopole structure is designed with the ability to withstand strength, durability and space efficiency which is widely used in urban corridors, substations, and long distance transmission projects.
The tower has been made of high quality steel and hot-dip galvanized to provide long life even in the harsh outdoor conditions. It has a single pipe design that minimizes land waste, but has an excellent mechanical performance.
Key Features
High-Strength Steel Construction
The tower is fabricated using premium structural steel such as Q235B, Q355B, or Q420B, ensuring excellent load-bearing capacity and structural stability for high-voltage transmission applications.
Hot-Dip Galvanized Protection
All components undergo hot-dip galvanizing in accordance with ISO1461 standards, forming a durable zinc coating that resists corrosion and extends service life in harsh weather conditions.
Space-Saving Monopole Design
Compared with traditional lattice towers, the single pipe structure offers:
-
Smaller footprint
-
Cleaner visual appearance
-
Faster installation
-
Reduced right-of-way requirements
This makes it suitable for urban and highway transmission routes.
