Monopole towers are widely used abroad, characterized by large-scale mechanical processing and installation, low manpower requirements, conducive to mass production and installation, and effective cost reduction and quality control through mechanized processing and installation. They also occupy a relatively small area. However, the drawback is that both processing and installation require large machinery, resulting in higher costs in China. Additionally, the tower has a large displacement and is not suitable for use as a microwave tower. It also requires certain transportation and construction conditions at the installation site, as well as higher foundation requirements compared to three-pole towers. It is recommended to use single-pole towers in locations with good transportation and installation conditions, low wind pressure, and lower heights.
In urban areas, various cables are distributed overhead. How to distinguish between electric monopoles and telecommunication monopoles?
1. How to distinguish between power poles and communication poles?
By remembering a few simple identification methods, it is easy to make a judgment. The material, height, phase lines, and markings of the poles can be used for identification.
In terms of material, 10 kV power monopoles are made of steel pipes and transmission towers, with the top of the pole being more than 10 meters above the ground, while 380V and below power monopoles are made of cement round poles, which are relatively "tall and sturdy". telecommunication monopoles are generally made of wooden square poles or cement poles, and are relatively "slender".
In terms of height, the distance from the power pole to the ground is between 10 meters and 15 meters, while the height of the telecom pole is around 6 meters.
In terms of phase lines, power lines are arranged in a "three-phase line" or "four-phase line" pattern, with each conductor maintaining a certain distance on the pole and supported by insulating materials, while communication circuits are bundled, and the lines often intersect.
In terms of markings, power poles have obvious line and pole number markings, with white background and red letters, while communication poles also have relatively obvious markings of the operating unit, generally with a black background and white letters.
2. How to ensure the safety of electric monopoles?
Transmission monopole and power lines do not have any impact on human health and are reliable in terms of safety. Cement power poles are allowed to have longitudinal cracks, but the crack length should not exceed 1.5 to 2.0 millimeters.
