MV backbone revamp – airport

Work preparation and project follow-up for the renewal and reinforcement of the medium-voltage backbone at Brussels Airport, focused on new substations, new switchgear, new cable routes and the wider electrification of the infrastructure.

Project description

For Imtech Belgium, I work as work-preparation engineer and project manager on the medium-voltage project "Stragrid" at Brussels Airport. Within this project, Imtech, as part of the Cordeel Group, works together with Mobix as a subcontractor on a major renewal of the existing medium-voltage infrastructure.

The project aims to reinforce the existing 11 kV medium-voltage network and make it future-ready. New medium-voltage substations and new MV switchgear are being installed, and ageing paper-lead cables are being systematically replaced with new cable connections that better match the airport's current and future power demand.

Besides renewing the installations, the project also includes laying entirely new cable routes. These are realised through classic trenching, but also through directional drilling at locations where open excavation is less desirable or technically less feasible. In this way, the new network is integrated into a complex and operational airport environment where continuity and reliability are essential.

The assignment is therefore not just about replacing existing components, but about building, step by step, a more robust medium-voltage backbone that can support the airport's further growth, increased power demand and electrification. Within that context, the focus is on solid preparation, clear coordination between the parties involved and technical choices that remain practically feasible during execution.
