Electrical distribution network construction
Service
We build and upgrade electrical distribution networks
We build and upgrade electrical networks in power installations rated up to 110 kV. Our work includes the construction of high-voltage substations and cable lines, the installation of medium- and low-voltage switchgear, and the construction and upgrade of metering systems.
We work on both new sites and existing electrical installations. In some cases, a completely new connection is required. In others, outdated equipment must be replaced, or the system needs to be made more reliable. Together with the client, we define a solution that fits the site, the technical requirements, and the project scope.
Our day-to-day work with distribution network operators has taught us to account for technical requirements, site coordination, and real working conditions. We carry out our work so the completed installation is properly built, tested, and ready for use.
Distribution network construction
How we can help
Our work covers the key parts of electrical distribution networks — from substations and cable lines to switchgear upgrades and metering systems.
01
Construction of high-voltage substations and cable lines
We build high-voltage substations and cable lines rated up to 110 kV. Our work includes the installation of equipment, cables, terminations, connections, and earthing systems, followed by the required inspection and testing.
On high-voltage sites, proper work sequencing and smooth coordination with other parties are essential. We approach the work as a complete process, so even the more complex stages are clearly organised and the project can move forward at a steady pace.
02
Medium- and low-voltage switchgear replacement, retrofit, and installation
We replace and install medium- and low-voltage switchgear. Where full replacement is not required, we carry out retrofit works to upgrade worn or outdated parts of the existing equipment.
This helps extend the service life of the installation and focus the upgrade exactly where it is needed. Before the work begins, we assess the condition of the equipment and define a practical, technically sound solution.
03
Construction, upgrade, and testing of metering systems
We build and upgrade electricity metering systems and carry out the required testing and verification. Our work includes installing metering equipment, making the necessary connections, and checking that the system operates correctly.
Accurate metering provides a clear view of energy use and forms the basis for correct billing. A well-functioning metering system also helps detect irregularities that could otherwise go unnoticed.
