Abstract
The invention specifies an electrical cable with at least two electrical conductor cores (1), which are stranded together, and each of which consists of an electrical conductor (3) enclosed in insulation (2), and with a sheath (5) of insulating material that encloses the conductor cores (1). To protect the cable, which in itself is fully functional, from red-hot particles, the sheath (5), which has a wall thickness of at least 0.5 mm, is covered with a barrier in the form of a flameproof strip (6), which is wound in at least one course with overlapping edges. The strip (6) is covered with a layer (7) of a material that swells when exposed to moisture and that is surrounded by an outer sheath (8) of insulating material.
