Comprehensive services for the assembly and installation of power transmission lines, including foundation installation, tower erection, and wire stringing.
Power line construction: from foundation
to cable stringing
to cable stringing
01
Foundation installation
A reliable foundation is the key to the stability and durability of any power transmission line. We perform a full cycle of work on the construction of foundations for all types of towers:
The work is carried out strictly according to the project, in compliance with regulatory requirements and technologies, which ensures high reliability and durability of the foundations even in complex climatic conditions.
- Reinforced concrete, metal, anchor, and non-standard structures
- Drilling boreholes considering the site's geology
- Reinforcement and formwork installation
- Concreting using modern mixtures and additives
- Strength control, compliance with the deadlines for achieving the design concrete strength class
The work is carried out strictly according to the project, in compliance with regulatory requirements and technologies, which ensures high reliability and durability of the foundations even in complex climatic conditions.
02
Installation of power transmission line towers
Tower installation is one of the key stages in power line construction. Our team of specialists ensures accurate and safe installation:
We guarantee the reliable installation of towers that can withstand all operational loads and weather impacts.
- Assembly and installation of metal and reinforced concrete towers on-site
- Working with anchor, suspension (tangent), and angle towers
- Use of modern specialized machinery: cranes, drilling and crane machines (DCM), work platforms/lifts
- Precise alignment and positioning according to the design
- Adherence to all safety requirements and construction regulations
We guarantee the reliable installation of towers that can withstand all operational loads and weather impacts.
03
Stringing of wires and cables
The final and equally critical stage is wire installation. We ensure precise and safe line stringing:
The work is carried out by a qualified team in compliance with all standards, ensuring reliable and safe operation of the power transmission lines.
- Stringing of overhead power line wires (6–110 kV)
- Use of professional equipment: winches, tensioners, dynamometers
- Control of tension and sag in accordance with regulations (PUE, SNiP, etc.)
- Organization of tension sections and installation taking into account temperature compensation
- Testing and inspection of lines before commissioning
The work is carried out by a qualified team in compliance with all standards, ensuring reliable and safe operation of the power transmission lines.
We don't just erect towers — we design and build reliable power transmission lines that won't collapse from strong winds or fail due to calculation errors.
Accurate calculation, proven materials, and installation that doesn't need to be redone.
