Siemens is to supply transformers for the cross-channel HVDC link between France and the UK, the company announced this week.

The firm said it will deliver four transformers of 400 kV and 315 MVA each to the UK’s National Grid, which plans to replace old transformers in the cross-channel link.

The order includes the supply, installation and commissioning of the transformers for the Sellindge converter station in England. Siemens plans to complete the work by mid-2019.

The scope of work will include installing the new units to fit precisely in the system as, for example, the wall openings for cooling all devices are located at different points, Siemens said.  

The new transformers are quieter, have lower transmission losses and will significantly improve the system’s reliability, the company added. In addition, all transformers will be equipped with a sprinkler system for fire safety.

The 73 km, 2 GW transmission project is expected to power around three million households at a cost of $1.45bn and is planned for completion in 2020.

Siemens has also been contracted to supply two HVDC converter stations for the project.
