  • Transmission networks

    We build, renovate and maintain 110 kV transmission networks. We use high-quality project management methods, versatile tensioning equipment and other tools that enable safe construction. We build traditional H-pillar lines as well as modern I-pillar lines that blend well into forest landscapes and enable a narrower transmission line right-of-way.

  • Substations and industrial services

    We build, renovate and maintain substations and switchgears for network companies and industrial operators. It is particularly important for us to ensure the safe operation of the network. We carry out projects and extensive maintenance on schedule drawing upon our solid expertise. Our experts use modern equipment to carry out, for example, transformer and switchgear maintenance, relay tests, transformer oil analyses and shielding gas measures, not forgetting network condition monitoring by means of thermal cameras, PD measurements, etc.

    We are always ready. Our extensive and high-quality measurement and maintenance equipment as well as our skilled staff serve you 24/7. For a long time now, we have provided contingency and failure services for several network companies as well as acted as assisted industrial companies with annual maintenance. We also provide electrical operation management services.
