accountable team.
From the first calculation to switching on the power — one team, no subcontractors.
Route
We set the line route and obtain the required consents.
Overhead lines
We install poles, cross-arms, insulators and conductors.
Underground lines
We dig trenches, lay the cable and make the joints.
0.4 kV networks
We connect consumers and energise the network.
10kV power lines and 0.4kV networks
Medium- and low-voltage electrical infrastructure
Connecting an industrial or commercial site to the electrical grid involves medium-voltage work executed correctly and safely. We build overhead and underground 10kV power lines, sized for your application’s power needs.
For internal distribution, we build 0.4kV networks that carry energy from the transformer substation to consumers, complying with current technical standards.

A complete solution, from a single team
We can deliver the entire power supply chain: a 10kV power line, a 10/0.4kV transformer substation and a 0.4kV distribution network. This way you avoid coordinating between several suppliers and have a single responsible team.
With proven experience in high-voltage projects and over 12000 completed projects, we carry out this work in line with regulations and in complete safety.




Frequently asked
questions.
We build overhead and underground medium-voltage 10kV power lines, as well as low-voltage 0.4kV networks, to connect industrial and commercial consumers and residential complexes.
Yes. We prepare the technical documentation, coordinate with the energy supplier and carry out the connection, testing and commissioning, so the work is commissioned legally.
Yes. We can deliver the complete solution: a 10kV power line, a 10/0.4kV transformer substation and the 0.4kV distribution network, all from the same team.
