Claim:
Electrical cable comprising: two portions, a first portion has at least two electrical conductor cores, which are stranded together, and each of which includes an electrical conductor surrounded by an insulation, and with a first sheath of insulating material that encloses the conductor cores, wherein in order to protect the cable, said first portion which in itself is complete and fully functional, said first sheath, has a wall thickness of at least 0.5 mm, said firs portion being covered with a second portion which serves as a protecting sheath of said first portion, said second portion having at least two specific coatings, a first coating being a barrier in the form of a ribbon, which is wound around said first portion in at least one course with overlapping edges and which is made from a material which is both flame proof and resistant against red-hot particles configured to prevent such red-hot particles from damaging said first sheath of said first portion; and said first coating barrier in the form of a ribbon being covered with a second coating of a material that swells when exposed to moisture, said first and second coatings of said second portion being contained within a second outer sheath of insulating material, such that water that enters through said second outer sheath is captured and prevented from spreading longitudinally along said cable by said second coating of material that swells when exposed to moisture.
