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.

Abstract: A method for preparing an HVDC cable for jointing or termination includes the step of providing a section of an HVDC cable comprising a conductor surrounded by a first semiconducting layer, and at least one insulation layer of a first polymer material surrounding the first semiconducting layer, where the insulation layer comprises conductive volatile by-products. A tape of a second polymer material is provided, where the additional layer comprises conductive volatile by-products. The tape is lapped onto the insulation layer thereby forming an additional layer. Heat is applied to crosslink the additional layer and redistribute the conductive volatile by-products.
