27 As the energy transition gathers speed, new renewable energy capacity is driving a shift to super- powerful high voltage 525 kV cables that carry nearly double the amount of power across land and under the sea than previous systems could. Prysmian Group has launched its new 525 kV HVDC cable technology, making a significant step forward towards more efficient, reliable and eco-friendly integrated solutions for high voltage systems. Prysmian’s 525 kV systems can connect remote power generation areas such as wind generationrich regions to major consumption centers, typically located far from renewable energy sources, while also reducing the required land usage and ensuring lower environmental impact. These solutions are helping its customers meet their energy goals quickly, more effectively, and at a lower cost. The pace at which renewable power needs to be connected each year must increase if governments are to meet challenging emissions-reduction targets: installing a more robust power each link is the only way to deploy the needed energy infrastructure in time. Prysmian Group’s integrated 525 kV solutions for the energy transition encompass all stages of a land or submarine project, spanning every phase from design and engineering knowhow to cable manufacturing, and then to installation on land, or underwater with the group’s continually expanding fleet of state-of-the art vessels. Prysmian’s 525 kV extruded land cable systems are qualified with two different insulation materials, XLPE and P-Laser, both designed to operate at very high electrical stresses. The newly developed XLPE material allows reaching cable voltage levels up to 600 kV, while reducing thicknesses at standard voltages with lighter and less expensive cables. P-Laser cable technology is based on a High-Performance Thermoplastic Elastomer (HPTE) insulation, an in-house developed insulation material based on polypropylene. P-Laser is fully recyclable, a key advantage for the end of life stage of obsolete HVDC links. The P-Laser production process has a low energy consumption, so its carbon footprint is up to 30% less than for XLPE. P-Laser technology is fully compatible with existing cable accessories and can be integrated in networks using different insulation technologies. Prysmian Group is now launching its 525 kV XLPE submarine cable into the market with tenders in both Northern Europe and the Mediterranean. Prysmian’s MIND cables are the only technology installed and in operation at depths of 1600 m.
