Export Cables
Please note that export cables connect the offshore transformer (substation) to either; shore or an offshore HVAC-HVDC converter station for onward transmission via HVDC cabling. Please see the converters page for planned converter stations and transmission cables.

The export cable length does not generally include the onshore component. The exception is when the onshore substation is close to shore.
