The power cable comprises a conductive core and at least one coating consisting of a material comprising an inorganic compound having a layered structure and an organic compound inserted between the layers of the inorganic compound. The inorganic compound comprises a mineral oxide in the form of a clay, and the organic compound comprises a polymer, monomer or oligomer. The coating comprises, based on the above structure, an insulator or an external coating, or, in the case of a medium-to-high tension power cable, includes at least a semiconducting shield based on the above structure. An Independent claim is given for fabrication of the power cable, comprising: (a) treating the inorganic compound, preferably clay, with an agent, preferably selected from a tertiary ammonium salt, polyethylene oxide and a phosphorus derivative, that ensures its compatibility with the organic compound; and (b) mixing the obtained composition with the organic compound at a temperature higher than that of softening or fusion of the organic compound, to obtain a material comprising the organic compound inserted between the layers of the inorganic compound. |
