Method for manufacturing a fire-resistant and/or fire-retardant cable

A method for manufacturing a cable having at least one elongated electrically conducting element and at least one composite layer surrounding said elongated electrically conducting element, said method comprising the steps of:

• forming the composite layer surrounding said elongated electrically conducting element by applying a tape of fibrous material impregnated with a geopolymer composition around said cable, and wherein said tape, impregnated and dried, is delivered from a roll prepared according to steps as follows:
• i) impregnating a non-woven fibrous material with a geopolymer composition, to forma tape impregnated with said geopolymer composition,
• ii) heat-treating the impregnated tape obtained in step i), to form an impregnated and partially dried tape, and
• iii) forming the roll by winding the impregnated and partially dried tape from step ii) on itself.
