Building the energy infrastructure of the future.

Power line design

Overhead and underground lines at any standardised nominal voltage, including 110, 220 and 400 kV.

Routes and documentation

We establish overhead and underground line routes and prepare technical documentation for new lines, extensions and upgrades.

Electrical and mechanical sizing

We calculate conductor and cable cross-sections, mechanical loads and insulation requirements.

Line equipment

We specify poles, towers, insulators, accessories and earthing solutions according to the design.

Optical fibre and specifications

We design optical ground wire (OPGW) and define equipment and material specifications.

Power line construction

Overhead and underground lines at any standardised nominal voltage, including 110, 220 and 400 kV.

Overhead line installation

We install poles, towers, insulators, conductors and accessories for new lines, extensions and upgrades.

Underground line construction

We lay underground power cables and install joints and terminations according to the design.

Earthing and OPGW

We construct earthing systems and install ground wire, including optical ground wire.

Testing and acceptance

We perform high-voltage tests and measurements and prepare the works documentation for acceptance.

Substation design

Transformer substations, switching substations and the electrical installations of power plants at any standardised nominal voltage.

Main installations
