General – Power Transmission
Prysmian Group has reached a key technology milestone in the field of Power Transmission, thus confirming its prominent role and commitment to support the energy transition.
The world leader in the cable industry announces the successful development and testing of the first 525 kV extruded submarine full cable system for High Voltage Direct Current (HVDC) applications.
This breakthrough innovation in cable technology will enable a massive increase of the maximum transmission capacity of bi-pole systems up to more than 2.5 GW, which is more than double the value achieved with 320 kV DC systems currently in service.
The one-year prequalification testing was carried out per international standards including CIGRE TB-496 and witnessed by a third-party certification body.
“Prysmian Group has always been at the forefront in the development of innovative and advanced technological solutions for power grids, namely land and submarine cable systems for HVDC applications,” stated Valerio Battista, CEO Prysmian Group. “This new milestone confirms our commitment and prominent role in the development of power grids infrastructure, key for the energy transition.”
HVDC cable links are key components of sustainable energy systems, to transmit large bulks of electricity over long distances, often across or between countries.
