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. Number of Export Cables 2 Average length per cable 22 km Transmission type (e.g. HVAC) HVAC Nominal voltage 132 kV Maximum voltage 145 kV Power rating 176 MVA Number of cores 3 Conductor type Cu Section 630 (2x21km)/1000 (2x0.2km) mm2 Insulation XLPE Number fibre optics Minimum bend radius (MBR) Burial depth 1 m Comments The length of the cables is 21km and 23km Land cable is 21.2km Onshore Cables (new) Number of onshore cables 6 Average length per cable 21.3 km Comments 145kV, trenches being around 2.2m wide and 1.6m deep Array Cables Array cable length 81 km Estimated cable length In purchased database Transmission type (e.g. MVAC) MVAC Nominal voltage 33 kV Maximum voltage 36 kV Burial depth 1 m Number of cores 3 Conductor type Cu Section 400 (26 km)/185 (56km) mm2 Insulation XLPE Power rating Number of fibre optics Minimum bend radius (MBR) Comments There will be two different types of infield cables connecting the turbines and the offshore substations. Type one (27kg/m) has a total length of 26 kilometres and will be used to connect the turbines closest to the substations, while type two (18kg/m) has a total length of 56 kilometres and will connect the turbines further out.
