An energy cable includes, at least one cable core including an electric conductor, a crosslinked electrically insulating layer, and zeolite particles placed in the cable core. The zeolite particles are able to extract and absorb, very efficiently and irreversibly, the by-products deriving from the cross-linking reaction, so as to avoid space charge accumulation in the insulating material during cable lifespan. A method for extracting crosslinking by-products from a cross-linked electrically insulating layer of an energy cable core, which includes manufacturing the energy cable core containing zeolite particles, heating the energy cable core up to a temperature causing migration of the crosslinking by-products from the crosslinked electrically insulating layer; and then placing a metal screen around the energy cable core.
An energy cable comprising at least one cable core comprising:
A method for extracting crosslinking by-products from a cross-linked electrically insulating layer of an energy cable core, comprising:
