Prysmian Group has gained verification of its higher voltage cable system technology for offshore wind inter-array networks. The group announces the completion of type testing of its 66 kV cable system in accordance with CIGRE and IEC test protocols, as part of the Carbon Trust’s Offshore Wind Accelerator (OWA) programme.
Developers can expect to reduce their overall offshore wind farm capital expenditure by up to 15% by raising the inter-array voltage level to 66 kV. Prysmian has now type tested a 3-core, 66 kV EPR insulated “wet-design” cable system with aluminium conductor and integrated optical element. The solution includes factory, field joints and plug-in terminations and EPR insulation. The qualification process was carried out in Prysmian laboratories in the UK and in Italy.
