EHV Interlinks and Connections
We class EHV interlinks and connections as infrastructure we construct designed to operate at voltages above 22kV. In the UK this has traditionally meant power construction at 33kV and above. Our experience in this is vast comprising of many projects constructed at all voltage levels between 33kV and 400kV. Additionally we are one of a small number of UK contractors to have successfully completed circuit construction with design voltage of 525kV DC.
Our experience in this area has provided customers such as Balfour Beatty, National Grid, Prysmian Cables, and Scottish Power the confidence to appoint us as their chosen contractor.
