Prysmian Group is set to launch a new cable technology for the development of power-transmission grids that will ensure higher electrical performances, lower costs, and better environmental sustainability. The Group announced the successful development and testing of its new P-Laser 600-kV cable system for high-voltage direct current (HVDC) applications.
“This milestone innovation shapes the progress of the entire HVDC cable industry, reaching 3.5 GW per bipole, the highest power rating ever, with cost reductions of up to 30% per transmitted MW,” said Massimo Battaini, Senior VP of Energy Projects at Prysmian Group. “The successful testing at 600 kV is further proof of the quality and robustness of the P-Laser insulation technology” he added.
P-Laser uses an in-house developed thermoplastic material (high-performance thermoplastic elastomer or HPTE), which permits a more efficient cable production with lower environmental impact than traditional XLPE, where the manufacture is performed in a single and continuous process. A key feature of this new insulation technology is that, compared to XLPE, it does not require a chemical reaction during manufacture to achieve the material properties required for the long-term electrical integrity of HVDC insulation systems.
This feature gives the additional benefit of shorter production times and results in reduced energy consumption and lower greenhouse gas emissions. P-Laser technology is fully compatible with existing cable and accessory technologies and provides a better electrical performance and higher reliability than conventional XLPE-insulated cables.
