High-voltage (HV) overhead and underground power grids

In the construction of high-voltage power lines, we deal with:

  • Excavation operations, foundation casting, erection, carpentry of simple or double backhoe supports.
  • Work on laying and adjustment of twin, triple, quad conductors and the guard rope.
  • Interventions on HV cable ducts, taking care of the design and installation of civil works.

Depending on the project, we perform different types of laying. The tubular one and the open trench one are the ones we carry out by performing trench excavation. The laying of the cable is done by winching.
