Sumitomo Electric Industries Limited has announced the successful completion of the Greenlink Interconnector Project, further showcasing its expertise in cable manufacturing and installation.

This involves the installation of high-voltage direct-current (HVDC) and fibre optic cables for its client, Greenlink Interconnector Limited.

The project employs Sumitomo Electric’s HVDC cross-linked polyethylene (XLPE) cables for submarine and underground electricity interconnection, linking the existing electricity grids in Ireland and the United Kingdom.

Greenlink will provide a new grid connection between Great Island in County Wexford, Ireland, and Pembrokeshire in Wales, UK. The project included the manufacture and installation of onshore HVDC cables along a 24 km route in Ireland, a 6 km route in Wales, and submarine cables along a 160 km offshore route. Electricity flows in either direction, depending on supply and demand in each country.

A key milestone was achieved with the successful completion of all testing, commissioning, and handover of the cable system to the consortium partner, Siemens Energy AG. The trial operations will commence in the coming months.
