The company will supply 95 kilometres of copper wire to the east coast development, connecting the 67 Siemens 6MW turbines. Construction of the cables is expected to begin next year at JDR's Hartlepool facility.
The Cambridgeshire-based firm will also supply hang-offs, connectors and repair joints with the cables.
JDR was handed the contract by VBMS (formerly VSMC), which was appointed by Norwegian developers Statoil and Statkraft to carry out the cabling work.
Last week, Tekmar Energy was handed the contract to supply its Teklink cable protection system to the Dudgeon project.
Dudgeon is located 32 kilometres off England's east coast and commissioning is expected for 2017.
