Steel power poles are pole-shaped or lattice structures that support overhead power transmission lines and overhead ground wires, maintaining a specific distance between them and the ground. Lattice structures are the most commonly used and are the primary structures for ultra-high voltage power lines. They can be categorized as self-supporting towers and guyed towers, with grounding methods including horizontal extension grounding and deep-buried grounding electrodes.

Based on their functions and positions in the power lines, there are six structural types: straight poles (also known as intermediate poles), tension poles (also known as load-bearing poles), angle poles, terminal poles, crossing poles, and branching poles. The pole tower structure, which includes substation steel structure, is a hyperstatic structure, subjected to loads such as wind, ice and snow, seismic, and conductor self-weight loads, all of which are dynamic loads that vary over time.

Strictly adhere to national and industry production and manufacturing standards, as well as the ISO quality system. As one of the top steel tower manufacturers, we take responsibility for our product manufacturing processes, for their use, and for any issues that may arise!
These were 128 pieces of 60 KV metal electric poles and extensions. We made the revised design that tower bodies were made of Grade 65 steel and extensions used Q345 steel (China standard). This was approved by client. Our steel power pole supplier fabricated them within 3 weeks and delivered to Callao, Peru. These transmission poles are now functioning well.
