Italian outfit Prysmian Group has launched two new 525kV cable systems, one qualified with P-Laser and the other with XLPE insulation, that can be utilised in the offshore wind sector.
The company said the systems are designed at a higher voltage level and with large conductor cross-sections to provide optimal technical solutions for long distance high power transmission with minimised land use.
Prysmian said P-Laser is a 100% recyclable eco-friendly high-performance cable technology, which uses a ‘zero-gas’ process reducing CO2 emissions by up to 30%
The system is fully compatible with existing HVDC cables and accessories and has over 30,000km manufacturing experience in other types of power cable networks, the company said.
An in-house developed material, called High Performance Thermoplastic Elastomer, is also incorporate and helps to increase thermal performance.
The XLPE system uses a new insulation compound specific for HVDC application, Prysmian said.
Both technologies have also passed type tests at 600kV.
Prysmian Group executive vice president of the projects business unit Hakan Ozmen said: “This new milestone is a significant step forward for power transmission systems and the development of innovative and sustainable cable solutions in the industry.
“The 525kV cable systems can be an effective solution for the planned German HVDC corridor projects, providing the TSOs – TenneT, 50Hertz, TransnetBW and Amprion – with two proven technologies able to connect the wind generation-rich regions of northern Germany to the major consumption areas in the south, reducing the required land usage and ensuring a lower environmental impact.”
