JDR Cable Systems has successfully completed type testing of its next-generation 132kV subsea cables designed for both fixed and floating offshore wind projects, doubling the voltage capacity compared to current industry standards.
The development aims to support the deployment of larger turbines and enable wind farms to be located further offshore and in deeper waters, potentially reducing clean energy costs and aiding the UK’s net-zero emissions goals.
JDR’s 132kV static array cables were developed with support from the Offshore Wind Growth Partnership and tested at the Offshore Renewable Energy Catapult. Production will take place at JDR’s Hartlepool facility and a new plant in Cambois, Northumberland.
“We pride ourselves on providing solutions to the energy sector ahead of time,” said Joe Cole, JDR’s technology manager. “Our 132kV technology is critical for enabling larger turbines and deeper-water floating wind.”
In addition, JDR completed qualification testing of its 132kV dynamic cable design through the £1.6 million AHEAD project, part of the UK government’s Floating Offshore Wind Demonstration Programme. The cables endured over 1.5 million tension-bending cycles, confirming their durability in challenging marine environments.
JDR is also contributing technical expertise to the international standards body CIGRE and collaborating with the Carbon Trust to advance high-voltage array systems, reinforcing its role in offshore wind cable innovation.
