Wind Power

To date, ISEL has built more than 7 GW of power both in industrial facilities and in large projects for leading companies in the sector.

1. Installation

We have collaborated in the installation of more than 5.5 GW during our more than 18 years of experience in the field, collaborating with top-level companies and technologies.

Electrical works

It is the area where ISEL ENERGIA has had the greatest presence over the years. It could be said that the low and medium voltage electrical wiring inside the turbines is our strong point, highlighting:

  • Laying and connection
  • Medium voltage connection of cylinders and terminals
  • Assembly and connection of cells
  • Cell firing test
  • Transformer connection

Mechanical works

Another of the areas where we have more and more presence, continuously adapting to the evolution of current turbines. Among these works we highlight:

  • Assembly help
  • Bolt tightening
  • Elevator installation
  • Installation of cabinets, cells and transformers
  • Finishes and cleaning

2.Maintenance and retrofitting

We mainly carry out electrical, mechanical and hydraulic work, providing solutions to problems that appear with the wear of the turbines.
