Our Services

We have a multidisciplinary team of employees with specialised training in our areas of operation, always seeking the most innovative and efficient solutions in the services we provide.

Transmission Lines

We design projects, build, perform power upgrading (up-rating), and maintain overhead High Voltage lines (at 60 kV) and Extra High Voltage lines (up to 400 kV), to strengthen and expand the national power transmission network, interconnecting substations and linking power plants and major consumption units to the grid. We have the expertise to carry out “turnkey” projects, covering all stages in the construction of a line, namely:

  • Preliminary route study
  • Topographic survey
  • Profile and plan definition
  • Design 
  • Right-of-way clearing
  • Stakeout
  • Structure erection
  • Cable stringing, tensioning, securing, and splicing
  • Shield wire and optical fiber installation 
  • Commissioning
  • Marking
