Prysmian claims new tech milestone in ‘Power transmission grids’


Prysmian says its ‘P-Laser 525 kV is the first fully recyclable environmentally friendly HVDC cable’ offering ‘increased power transmission capacity and lower system costs by more than 10%’

Claimed ‘world leader in the energy and telecom cable systems industry,’ Prysmian Group, has launched ‘a new breakthrough cable technology for the development of power transmission grids that will ensure better environmental sustainability, higher electrical performance and lower costs.’

The news comes just a week after Prysmian claimed 'another world's first' with 'the highest fibre count cable to date installed in Australia,' as reported here in iTWire

The company has also announced ‘the successful development and testing of its new P-Laser 525 kV cable system for High Voltage Direct Current (HVDC) applications.’

Prysmian’s Massimo Battaini, Senior VP of Energy Projects said: “This is a significant and important new technology that shapes the progress of HVDC in the cable industry and reconfirms once again our undisputed leadership in driving technological innovation within the sector.

“We are proud to offer this advanced technology to our customers engaged in developing, extending and upgrading their power grids, while seeking to reduce environmental impacts with solutions that provide them with superior system performance and cost benefit” he added.

Unique environmental performances with lower CO2 emissions and fully recyclable materials

P-Laser is the name Prysmian has given to ‘the most advanced and innovative technology that permits a more efficient cable production with lower environmental impact than traditional XLPE (Cross-Linked Polyethylene).’

The company says that ‘manufacture is performed in a single and continuous process and does not require chemical reactions to achieve the properties required for the long term electrical integrity of HVDC insulation systems.’

This feature is said to ‘give the benefit of shorter production times and results in both reduced energy consumption as well as lower greenhouse gas emissions’ and that ‘P-Laser is particularly suitable for HVDC applications’ and that ‘it is the first HVDC cable that can be fully recycled at system end-of-life.’

Higher electrical performance enabling up to 10% cost reduction in power transmission

Prysmian also states that ‘P-Laser technology is fully compatible with existing cable and accessory technologies, provides better electrical performance and a higher material integrity for HVDC in comparison to traditional XLPE-insulated cables.’

From an efficiency perspective, Prysmian claims ‘P-Laser technology has higher thermal performance properties, which increase the power transmission capability of the cable system for a given conductor size, thereby enabling average overall cost reductions of approximately 10% per transmitted MW.’

The company boasts that ‘P-Laser application to HVDC underground and submarine systems marks a world first in the cable industry,’ and says ‘this milestone achievement follows the Group’s recent announcement of the successful testing of the XLPE extruded cable solution at the same voltage level (525 kV DC) in December 2015 and is further recognition of the clear commitment and leading role Prysmian has towards innovation in cable technology.’
