▎ 摘　　要

NOVELTY - The cable has an electrically conducting lengthened element e.g. monocorps driver and multicorps driver, equipped with an external protection sheath i.e. semiconductor sheath, which is made of a polymeric material for surrounding the electrically conducting lengthened element. The external protection sheath includes a carbonaceous agent i.e. carbon nanotubes, which are made of graphene. The external protection sheath includes a hydrated fireproofing mineral load, inert load and reinforcements agents. USE - Electric cable for transporting energy in submarine areas, terrestrial areas and aerospace areas. ADVANTAGE - The protection sheath is made of the polymeric material for surrounding the lengthened element, where the protection sheath includes the carbon nanotubes which are made of the grapheme, thus guaranteeing better electric and mechanical properties of the cable. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a plate of an electric cable. '(Drawing includes non-English language text)'
