In the Yamal-Nenets Autonomous Okrug, power engineers have begun implementing a technology for strengthening and replacing the foundations of power transmission line (PTL) supports, which extends the service life of structures by more than 30 years. This was reported by the "Rosseti Tyumen" company.

The solution is based on modular screw piles with a composite material insert. The composite hardly conducts heat and prevents permafrost thawing, reducing the risk of pile displacement due to temperature fluctuations, waterlogging, and soil heaving. Anchors enhance adhesion to the soil and increase the bearing capacity of the foundations. The technology has already been tested during pilot industrial operation on ten high-voltage power line supports.

To install piles in hard-to-reach areas, a mobile small-sized drilling rig on tracks was created. It allows repairs to be carried out without relocating supports and without restricting electricity supply to consumers. "Rosseti" noted that the solution is universal and can be applied not only in the power grid complex but also in other sectors of the fuel and energy complex, industrial, and civil construction.
