  • Publication number: 20180019582
    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.

  • Patent number: 9871357
    Abstract: A cooling system for cooling a power transmission system that includes a cable configured to carry a current corresponding to a transported electric power may include: a cooling device configured to remove heat from the power transmission system; a power supply system configured to extract a power fraction from the cable and configured to supply the cooling device with the power fraction; and a control unit configured to control an amount of the extracted power fraction in response to a parameter of the electric power. When the parameter is higher than a threshold, the extracted power fraction is equal to a first value that depends on the electric power carried in the cable through a first function. When the parameter is lower than the threshold, the extracted power fraction is equal to a second value that depends on the electric power carried in the cable through a second function.
