Prysmian Groupย reached a key milestone with itsย Prysmian Group 525 kV HVDC cableย development. The company created and tested the worldโs first 525 kV extruded submarine cable system for High Voltage Direct Current (HVDC) use. This breakthrough pushes clean energy technology forward and strengthens global power grid innovation.
Prysmian Group 525 kV HVDC Cable Raises the Bar
The new cable system can transmit more thanย 2.5 gigawatts (GW)ย of power. Thatโs over twice the capacity of current 320 kV DC systems. Prysmian completed a oneโyear qualification program that metย CIGRE TBโ496ย standards and earned independent thirdโparty certification. As a result, the system proves high performance and solid reliability.
โThis achievement reinforces our leadership in developing power grid infrastructure that supports the global energy transition,โ saidย Valerio Battista, CEO of Prysmian Group.
Driving the Clean Energy Transition
HVDC systems allow efficient electricity transfer across long distances and between countries. With theย Prysmian Group 525 kV HVDC cable, the company strengthens its ability to deliver largeโscale submarine interconnectors. These links are vital for connecting offshore wind farms to national grids and expanding renewable power capacity.
This success also builds on earlier progress withย 525 kV HVDC underground cablesย used in Germanyโs grid projects. โNow, weโre applying the same innovation to submarine systems,โ explainedย Hakan Ozmen, Executive Vice President of Prysmianโs Projects Business Unit. โThis approach helps reduce costs for offshore wind and limits environmental impact.โ
Engineering Excellence Behind Every Cable
Prysmian combined materials science expertise with precision manufacturing to reach this milestone. The production process was fineโtuned for stability, accuracy, and efficiency. The full system includes flexible factory joints, rigid repair joints, and seaโland jointsโall designed for strong dielectric performance and long service life.
Through this achievement, Prysmian continues to lead in sustainable energy transmission and helps accelerate the worldโs move toward a cleaner power future.
