Thorne & Derrick International, a leading UK based Specialist Distributor of LV HV Jointing, Earthing, Substation & Electrical Eqpt are delighted to confirm receipt today of a new purchase contract order for an offshore wind farm project – this is to supply 33kV Tee Connectors (NEXANS EUROMOLD) and Inline Cable Joints (3M COLDSHRINK) following several rounds of technical qualification, specification and commercial submissions.

Thorne & Derrick’s technical submission for the jointing of the 33kV cables was accepted by the Senior Lead Cable Specialist based upon their 3M QS2000 range – the cable joint designed utilises a unique Cold Shrink delivery system. The 3M Cold Shrink products are supplied pre-stretched on a removable core for efficiency and ease of installation by the jointer with an integral electrical field control device and faraday cage pre-installed in the insulation body to reduce complexity during the installation.

As Approved Vendors to Vattenfall, the Swedish multinational power company, Thorne & Derrick will be supplying a 33kV Inter-Array Cable Accessory Package including medium voltage joints, connectors and cable cleats to support the installation of 19/33 (36)kV Single Core Submarine Cable with 24 Fibers (IEC 60502-2).

The cable insulation system features water tree retardant (WTR) XLPE material, consisting of an inner semi-conductive screen, insulation and outer semi-conductive screen extruded in same operation (triplex extruded) – 3M Cold Shrink provides secure sealing and insulating of medium voltage cable termination and connections up to 36kV.

The MV cable originally manufactured by Prysmian Draka was installed by VMBMS under contract to Vattenfall Vindkraft A/S at the Horns Rev 3 project in Denmark.

Thorne & Derrick can support the specification and supply of standard and customised Cable Termination & Jointing Systems up to 66kV including separable connectors for Interface C-F Outer Cone and Size 3 Inner Cone gas insulated switchgear – extensive ranges of Cold Shrink and heat shrink jointing technologies are available from stock for immediate delivery to reduce downtime periods on unplanned cable outages.

Horns Rev 3

Horns Rev 3 wind farm in the North Sea, 25-40 km off the Danish Jutland coast, is a defining point for Vattenfall’s production of wind power in Denmark and the rest of Europe setting new standards for the price of renewable energy from offshore wind farms and for the size of wind turbines in Danish waters.
  • Vattenfall Vindkraft’s agreement with the Danish State will make the production from Horns Rev 3 one of the cheapest in Europe, with a price for electricity of DKK 0.77 per kilowatt hour.
  • With the construction of Horns Rev 3 with a capacity of 406.7 MW, Vattenfall is on its way to becoming one of Europe’s largest producers of wind power.
  • For Horns Rev 3, Vattenfall has opted for the world’s most powerful wind turbine – MHI Vestas V164 of 8.3 MW.

Horns Rev 3 covers the annual electricity consumption of approximately 425,000 Danish households.
