NOVELTY - The utility model claims a fireproof cable, comprising: four-wire group; the number of the four-wire group is 5; and the included angle between each adjacent four-wire group is 72 degrees; the four-wire group is supported by the pentagonal supporting rod located at the central position of the cable body; the outer side of the four-wire group is provided with a winding belt, a graphene layer and a copper wire shielding layer close to the four-wire group far away from the four-wire group; halogen-free flame retardant polyolefin layer, double-layer steel belt and outer sheath, the gap between the four-wire group is provided with a filling layer. The utility model has simple structure, avoids using the traditional single-layer insulating layer wrapping way to wrap the wire cable but not fireproof, and high strength, preventing deformation and damage.
