Underground line

Since 2011, EQOS Energie has been diversifying and is currently addressing urban constraints associated with the transport of high voltage energy by providing an alternative solution: underground lines.

Overcoming the obstacles

The team of EQOS Energie’s Underground Line section is working to respond to the increasingly complex constraints on electrical energy transport.

Our know-how enables you to have one service provider that accompanies you throughout the study and realisation of projects at regional and national level. The synergy around our engineering activities, overhead lines, transformer stations and underground lines brings real added value to your projects.

We are your single point of contact for the implementation of your network, regardless of the obstacles we face.

More value for your projects

Our teams consist of men and women whose competences allow projects to be implemented by overcoming obstacles and basement clutter. As your partner, we work out with you the optimum solutions for the implementation of your network, from 63kV to 400kV.

Thanks to our project teams and their experience on site, we anticipate problems associated with the site plan and offer you turnkey solutions, from study to realisation.

Beyond obstacles

Every project is unique , this is why we attach great importance to find optimal solutions.

The infrastructures channel energy across rivers, railways and all other obstacles that appear on an optimal route.
We evaluate the ideal solution for your projects by assessing the constraints associated with the techniques employed to overcome the obstacles.

Our teams have the necessary means for constructing underground pipelines, traditionally or mechanically. As a complete service provider, our activities cover the total range of projects for the creation of underground lines:

  • Studies, creation and monitoring of plans
  • Civil engineering services
  • Underpinning
  • Unwinding of HV cables
  • Testing of ducting
  • Administrative monitoring
