How to select the appropriate type of power steel pole?

When choosing a suitable model of power steel pole, the following key factors need to be comprehensively considered:

1. The voltage level matches the specification

The voltage levels of power steel poles cover 10KV to 220KV, and different voltage levels correspond to different specifications and dimensions ‌    for instance：

·  10KV lines ‌ : Small steel pipe poles are usually adopted, such as hexagonal or octagonal cross-section designs ‌

·  110KV and above lines, ‌ : steel poles of larger size and higher load-bearing capacity are required. Some manufacturers have the production qualifications for 110KV transmission line steel pipe poles ‌ 

2.Pole Type and Functional Requirements

Select the type of pole based on the line erection scenario:

·   Straight bar ‌ : conventional straight section support;

·   Tension rods/terminal rods ‌ : used for line tension control or end fixation

·   Multi-loop steel rods ‌ : such as corner, single/double/four-loop steel rods, customizable design ‌

3.Environmental Adaptability

·  Anti-corrosion treatment ‌ : Prioritize the use of steel rods with hot-dip galvanizing both inside and out to extend their service life ‌

·  Climate conditions ‌ : Cold-resistant sheaths are required in high-cold regions, and anti-corrosion measures need to be strengthened ‌ in coastal areas

·  Mechanical strength ‌ : In areas with high wind load, the structural stability needs to be enhanced ‌

4. Customized Services
Most manufacturers offer on-demand customization, including:
·  Length range: 8 meters to 16 meters
·  Special scenarios: such as street lamp poles, communication towers, etc., not for power transmission purposes

5. Cost and Compliance with Standards
·  Price reference: Approximately 6,000 yuan per root for 10KV single-circuit steel poles (12-meter specification)
·  Industry standards: Must comply with DL/T646-1998 and other power industry norms

Through the systematic assessment of these dimensions, it is possible to ensure that the selection meets the engineering requirements and is economically viable.
