Zusammenfassung: | The utility model relates to the technical field of cables, in particular to an insulating fireproof cable, which comprises a plurality of cable cores and an insulating fireproof assembly, and the insulating fireproof assembly comprises an insulating sheath, a polyvinyl chloride resin layer, a tinfoil layer, an outer raised insulating layer, an inner raised insulating layer and alkali-free glass fibers. The plurality of cable cores are used for conduction, the cable cores are wrapped by the tinfoil layer, so that the plurality of cable cores are isolated, the possibility of open circuit is reduced, the polyvinyl chloride resin layer has good bending resistance and good toughness due to material characteristics, the toughness of the cable is increased, and the cable is not easy to extrude the internal cable cores during cable transportation and pulling. The protruding parts of the outer protruding insulating layer and the inner protruding insulating layer are staggered to form a space, the friction resistance |
