Electrical substations

We cover all voltage levels by applying efficient solutions.

A benchmark company in the sector with years of experience and development.

Approved by the main electricity transmission and distribution companies.

Development of international projects for specialist companies, promoters and transmission and distribution companies.

Our designs cover all voltage levels, adapting our solutions to the required degrees of demand, criticality and operability; from transformation centers or medium voltage sectioning centers (10 to 45 kV,...), generally intended for secondary distribution networks, rural electrification or even collection networks for renewable energies, to large high voltage substations (66 to 230 kV) and very high voltage (400-500 kV) generally intended for primary transmission networks.

  • More than 4,000 substations.
  • Different technologies: AIS, HIS, GIS.
  • Different configurations: single bar, double bar, transfers, switch and a half, switch and a third, ring.
  • Different functions: transmission and distribution, evacuation of wind generation, supply to industrial plants.

A completely comprehensive development with its own resources, covering all possible engineering phases:

The different phases:

  • Basic or conceptual engineering: technical and economic feasibility studies, connection studies, implantation studies.
  • Processing, conceptual, or administrative engineering, management of conditions.
  • Property engineering: development of bidding documents, preparation of offers, engineering review developed by third parties.

And the disciplines:

  • Civil engineering: earthworks, drainage, foundations, building.
  • Electromechanical engineering: design of support metal structures, earthing networks, electromechanical assemblies.
  • Electrical engineering: sizing of busbars and primary systems, auxiliary services, lighting, insulation coordination.
  • Control and protection engineering, including selectivity and coordination studies.
  • Commissioning of the facilities.
  • Supervision and site management.

Our designs and solutions are adapted to all the particular requirements of the project.
