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. 115-. (canceled)16. An energy cable comprising at least one cable core comprising an electric conductor , a crosslinked electrically insulating layer , and zeolite particles placed in the cable core.17. The energy cable according to claim 16 , wherein the electric conductor is formed by a plurality of stranded electrically conducting filaments claim 16 , and the zeolite particles are placed within voids among said filaments.18. The energy cable according to claim 16 , wherein the cable core comprises at least one semiconducting layer.19. The energy cable according to claim 18 , wherein the zeolite particles are placed in contact with the semiconducting layer.20. The energy cable according to claim 19 , wherein the semiconducting layer s an outer semiconducting layer surrounding the electrically insulating layer.21. The energy cable according to claim 18 , wherein the zeolite particles are placed into a semiconducting layer.22. The energy cable according to claim 21 , wherein the semiconducting layer is an inner semiconducting layer surrounding the electric conductor.23. The energy cable according to claim 16 , wherein the zeolite particles are ...
