Prysmian Group has developed and tested its new 700kV MI-PPL (mass impregnated) and 600kV extruded (XLPE) cable systems for high voltage direct current projects.
The company said that it is the first time in the cable industry that voltages at such high levels have been achieved.
It added that the cables will increase the power transmission capability by up to 15% beyond the previously HV 525kV XLPE technology and beyond that currently achieved with 600kV PPL technology.
Prysmian Group senior vice president energy projects Massimo Battaini said: “These are also the first developments in cable technology that enable HVDC power transmission systems beyond 3GW per cable bipole, and as such, are capable of more than double the power transmission capability of DC cable systems currently in service.”
