  • Submarine electrical cable and submarine cable operation method
    Patent number: 10373735
    Abstract: Submarine electrical cable system (100) having a substantially circular cross-section and comprising: a first insulated core (1) and a second insulated core (2); a three-phase cable (3) comprising three stranded insulated cores (8) the three-phase cable (3) being stranded with the first core (1) and the second core (2); an armor (4) surrounding the first core (1), the second core (2) and the three-phase cable (3).

  • Accessory for high voltage direct current energy cables
    Patent number: 9991690
    Abstract: The present invention relates to an accessory for high-voltage direct-current (HVDC) energy cables comprising: at least one element made from a crosslinked elastomeric polymer material, and at least one scavenging layer comprising zeolite particles. The zeolite particles are able to scavenge, very efficiently and irreversibly, the by-products deriving from the cross-linking reaction, so as to avoid space charge accumulation in the element during the accessory lifespan. Moreover, the zeolite particles can prevent the crosslinking by-products present in the element of a non-degassed accessory from migrating towards the insulating layer of the energy cable on which the accessory is mounted.
