Being developed by Norwegian energy firms Statoil and Statkraft, the £1.5bn wind farm is situated 32km off the North Norfolk coast in water depths of 18m to 25m.
Under the contract, JDR will deliver two inter-array cables, a 185mm² copper conductor cable and a 500mm² copper conductor cable, in two continuous lengths.
JDR will also provide accessories such as connectors, fibre optic patch panels, connectors, cable cleats, and subsea repair joints, as part of the contract.
Work under the contract will be carried out at JDR’s facilities in Cambridgeshire and Hartlepool, UK.
UK Government Business Minister Matthew Hancock said: "As part of our long-term economic plan we are working with the offshore wind industry to bolster a thriving manufacturing industry here in the UK, ensuring more energy jobs comes to our shores."
Initially, Statkraft and Statoil will build an onshore substation and lay cables on land before starting offshore construction in 2016.
Statoil will operate the wind farm, which is expected to be commissioned by the end of 2017.
The wind farm comprises 67 Siemens wind turbines, each with 6MW of capacity, generating enough power for 410,000 UK homes.
