Prysmian Group has recently completed the electrical type tests on its 66kV complete submarine cable system.
Tests were carried out according to CIGRE and IEC testing protocols.
The tested solution – that includes also factory, field joints and click-fit terminations – combines the use of EPR insulation with the cost effectiveness of wet design and aluminium conductors (copper conductors are also available), the company said in a press release issued 16 November.
Prysmian stated that the success in the qualification of its 66kV system will provide the necessary confidence to offshore wind developers to step the intra-array system voltage up from the typical 33kV to 66kV, ensuring a significant reduction in Levelized Cost Of Electricity and a higher competitiveness of future wind energy systems.
