Successfully tested 700 kV (PPL) and 600 kV (XLPE), the highest voltage ever reached for HVDC cable systems, resulting in transmission capacity increase by up to 15 percent and higher grid reliability
May 24, 2016
Prysmian Group, world leader in the energy and telecom cable systems industry has reached two record-breaking milestones in the field of power transmission and today announces the successful development and testing of its new 700 kV MI-PPL (Mass Impregnated) and 600 kV extruded (XLPE) cable systems for high voltage direct current (HVDC) applications.
These achievements prove the robustness and reliability of both XLPE and mass impregnated PPL technologies for HVDC applications to the highest voltage levels, the latter emphasizing the intrinsic potential of the Group’s PPL proprietary technology.
The voltage upgrades resulting from such achievements also allow increasing the power transmission capability by up to 15 percent beyond the previously highest voltage 525 kV XLPE technology and beyond that currently achieved with high performance PPL technology at voltage level of 600 kV, respectively.
These milestone achievements follow the Group’s recent announcement of the successful testing of the 525 kV DC XLPE and 525 kV P-Laser cable solutions in December 2015 and March 2016 respectively and are further recognition of the clear commitment and leading role Prysmian has towards innovation in cable technology.
HVDC cable links are key components in delivering sustainable energy systems for the bulk transmission of electrical power over long distances, whether across or between countries.
