Abstract (en)
[origin: EP2767984A1] The power and/or telecommunication cable comprises: a central conducting element (2); an internal semiconductor layer (3) surrounding the central conducting element; a first electrically insulating layer (4) surrounding the internal semiconductor layer; a semi-conductive transition layer surrounding the first electrically insulating layer; a second electrically insulating layer (6) surrounding the transition layer; and an external semiconductor layer (7) surrounding the second electrically insulating layer. The first electrically insulating layer is composed of fire resistant materials. The power and/or telecommunication cable comprises: a central conducting element (2); an internal semiconductor layer (3) surrounding the central conducting element; a first electrically insulating layer (4) surrounding the internal semiconductor layer; a semi-conductive transition layer surrounding the first electrically insulating layer; a second electrically insulating layer (6) surrounding the transition layer; and an external semiconductor layer (7) surrounding the second electrically insulating layer. A material of the first electrically insulating layer has an electric permittivity higher than that of a material of the second electrically insulating layer. The first electrically insulating layer is composed of fire resistant materials. The cable further comprises: a second semi-conductive transition layer surrounding the second electrically insulating layer; a third electrically insulating layer surrounding the second semi-conductive transition layer; an external protective screen surrounding the external semiconductor layer; and a sheath surrounding the external protective screen.
