Greener power cable is fully recyclable

4th July 2019


After completing one-year qualification testing in accordance with international standards, Prysmian is launching two new 525 kV extruded land cable systems, one qualified with P-Laser and one with XLPE insulation. These cable 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.

P-Laser is the first 100 per cent recyclable eco-friendly high-performance cable technology, utilising a ‘zero-gas’ process which reduces CO2 emissions by up to 30%. P-Laser is fully compatible with existing HVDC cables and accessories and has over 30,000 km manufacturing experience in other types of power cable networks. The P-Laser qualified cable system employs a Prysmian in-house developed material, called HPTE (High Performance Thermoplastic Elastomer) with proven enhanced characteristics, namely increased thermal performance, higher intrinsic reliability and greater productivity, making it the best solution for HVDC transmission lines at the highest voltage levels. The XLPE qualified cable system uses a new insulation compound specific for HVDC application. Both technologies have also successfully passed type tests at 600 kV.

“This new milestone is a significant step forward for power transmission systems and the development of innovative and sustainable cable solutions in the industry,” declared Hakan Ozmen, EVP, Projects Business Unit, Prysmian. “The 525 kV 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,” concluded Ozmen.
