Transmission Angle Steel Tower

1. Product Overview

The Transmission Angle Steel Tower is a core lattice truss structural facility for high-voltage and ultra-high-voltage overhead power transmission lines. As a classic Angle Steel Tower and essential Power Grid Tower, it is assembled with equilateral angle steel or composite angle steel through standard bolt connection technology. Known as the “steel backbone of the power grid”, this reliable Electrical Transmission Structure undertakes critical tasks of supporting, lifting, and tensioning power lines to ensure safe, stable, and continuous power transmission. It is the most widely applied, mature, and cost-effective mainstream Transmission Tower solution for global power grid construction projects.
