Pile for electric transmission lines (ETL) 325

The steel screw-type power line pole (PLP) is a welded steel pipe with a welded flange. The hollow trunk is cut at a 45-degree angle and may have 1 or 2 extensions. The hollow space inside the pole is filled with polyurethane foam (PUF). The pipe's wall is reinforced. It may have a hot-dip zinc coating and special paints.

Pile for electric transmission linesScrew piles, which are manufactured by the South Ural Screw Piles Plant "Egoza," are extensively employed for power station foundations due to their robustness, enduring nature, and ease of installation. In comparison to conventional methods such as concrete pouring, these methods are more efficacious and cost-effective for the installation of foundations.

Screw piles are renowned for their ability to disperse loads over a larger area, thereby enabling them to withstand significant loads on PTL foundations.

Furthermore, screw piles are easy to install on various types of soil, including sand, clay, gravel, and others. This approach will help to reduce the time and cost associated with installing PTL foundations.

The installation of screw piles is also feasible at any depth, thereby enabling the selection of the most optimal foundation option for specific terrain conditions. They are also resistant to seismic loads, which is especially important for power stations located in areas with increased seismic activity.

Screw piles are a reliable, efficient, and cost-effective solution for power station foundations. They provide high strength and stability while requiring minimal time and costs for installation.

They have been tested and repeatedly installed at facilities of FSK, PJSC Rosseti, and Inter RAO, respectively.
