Poles of electrical transmission lines

Could you imagine your life without electricity and all the benefits it provides?

It's hard to count how many times a day we use electricity. Many times. Every day. At home, in the office, in the store, and even on the street. Everywhere we go, we are surrounded by electrical appliances that have become indispensable helpers for us. In the evenings, the lights are on in our homes and a familiar TV show is playing. The Internet has become an indispensable attribute of our lives: from study and work to entertainment and games. But still, the most important values in our modern world are have become the connection with relatives and the opportunity to keep abreast of the latest news.

All of this and much more has become possible for us thanks to the long-distance transmission of electricity from power plants to end users. The transmission process takes place through power grids, which include voltage converters, power lines and switchgear.

Power plants transmit high voltages of hundreds of kilovolts, which need to be reduced to meet the needs of different users. For this purpose, converters and overhead lines of different voltages are used, which already deliver electricity to switchgear, where it is distributed to individual consumers.

We manufacture metal poles of electrical transmission lines. They are an integral part of the power transmission system. They serve as a structure for holding overhead line wires and lightning protection cables at a specified distance from each other and from the ground.

In addition, poles can also be used to change the order of wires on the line, organize branches and cross points. Poles of electrical transmission lines have different purposes depending on the functions they perform. You can learn more about the types and functions of poles of electrical transmission lines here.

Among the types of metal poles of electrical transmission lines, there are lattice poles and multifaceted poles. Although lattice poles are widely used, multifaceted poles are gaining popularity due to their advantages.

A multifaceted pole of electrical transmission lines looks like a faceted conical trunk with traverses for attaching overhead line wires. The structure of the trunk consists of separate sections (up to 12 m each), and the diameter of the pole trunk is determined depending on the load provided for it. Additionally, each pole is equipped with a ladder that provides quick access to its upper parts for maintenance or repair.


Multifaceted poles of electrical transmission lines are very lightweight and easy to install:

  1. First of all, you need to perform all the foundation work, and immediately before installing the pole, make sure that it is strong. The installation of multifaceted poles of electrical transmission lines includes the use of an anchor bolt foundation with which the pole is attached to the foundation.

  2. Next, proceed to assemble the pole sections. The sections must be fully assembled with all additional elements (service platforms, traverses, ladders, etc.).

The further installation process depends on the chosen method. There are several ways:

  1. Gradually, starting from the bottom, the sections are lifted and mounted one by one, connecting to each other under the influence of a pulling load (if they are telescopic), or fixed with bolts (if the sections are flanged). This method is mainly used when the area has insufficient open space to accommodate a fully assembled pole.

  2. All sections of the pole are connected to each other on the ground. After that, the fully assembled pole is lifted and fixed to the anchor bolt foundation using a flange connection.


Multifaceted poles of electrical transmission lines known for their aesthetics, enhanced strength characteristics and a number of other advantages, including:

    The design of poles based on multifaceted bent racks is characterized by the presence of stiffeners. They are resistant to twisting compared to lattice poles. There is no "domino effect", which is typical for electrical transmission lines on reinforced concrete racks and has catastrophic consequences. Due to their structural elasticity, multifaceted poles of electrical transmission lines are more resistant to wind loads. Also, they are considered to be the most vandal-resistant.
    A significant advantage of multifaceted poles of electrical transmission lines is that they require a small area for installation, unlike lattice poles. They are simply irreplaceable in conditions where installation space is limited.
    The cost of transportation of such poles is low, as it is carried out by placing the sections of the pole inside each other, due to its telescopic design. This greatly simplifies the process of transporting and unloading the components of the poles.
    The installation of multifaceted poles of electrical transmission lines does not take much time and labor due to the small number of assembly units. This is in contrast to lattice poles, which require a lot of elements to assemble.
    To extend the service life, protect against corrosion and weather factors (ice, etc.), the poles are subjected to anti-corrosion treatment by hot dip galvanizing. The service life of galvanized poles is 50-70 years.


For each specific project, taking into account its needs and features, it is important to individually approach the choice of a multifaceted poles of electrical transmission lines. Our engineers carefully calculate the loads and take into account all the requirements to select the optimal design. They pay attention to the number of sections, traverses, faces and other parameters to ensure the safety and reliability of the structure.
