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.

Desarrollo de proyectos internacionales para empresas especialistas, promotores y compañías de transmisión y distribución.

Nuestros diseños cubren todos los niveles de tensión, adaptando nuestras soluciones a los grados de exigencia, criticidad y operatividad requeridos; desde los centros de transformación o centros de seccionamiento en media tensión (10 a 45 kV,…), generalmente destinados a redes de distribución secundaria, electrificaciones rurales o incluso redes de recolección para energías renovables, hasta las grandes subestaciones en alta tensión (66 a 230 kV) y en muy alta tensión (400-500 kV) generalmente destinadas a redes primarias de transmisión.

  • Más de 4.000 subestaciones.
  • 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.
