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.
1. Strictly implement national and industry production process standards; we are a first-level supplier for the State Grid Corporation and an engineering contracting company recognized by national departments.
2. Comprehensive technical consultation and support before, during, and after sales.
3. Diligent and patient tower designers; final drawings are based on customer approval and signatures.
4. Comprehensive after-sales service with 7X24H response, taking responsibility for our products; providing guidance for after-sales installation and maintenance services.
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!
The service life of galvanized steel poles is about 15 years and is affected by the following factors:
1.External environmental factors: temperature, humidity, salt spray, chemicals, UV radiation, wind, ice and snow load, seismic activity, etc.
2.Design and manufacturing quality: design rationality, material selection, production process, anti-corrosion treatment.
3.Installation and maintenance status: construction quality, regular inspection, maintenance, load management, and lightning protection measures.
In order to extend the service life of power steel poles, the following measures can be taken: Choose models with strong corrosion resistance and earthquake resistance, apply an anti-corrosion layer on the surface of the metal poles, equip with better insulation equipment, and strengthen the grounding of the metal poles.
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.
