High-temperature-resistant fireproof security cable

The utility model discloses a high-temperature-resistant fireproof security cable which comprises an outer protective layer, an inner lining layer is arranged in the outer protective layer, an insulating protective layer is arranged in the inner lining layer, an insulating layer is arranged in the insulating protective layer, and a filling layer is arranged in the inner lining layer and located between the insulating protective layers. According to the high-temperature-resistant fireproof security cable, the inner lining layer and the insulating protection layer in the security cable adopt the double-sided film reinforced synthetic mica tape, so that the electrical insulation performance of the cable can be greatly improved, and meanwhile, the cable filling material composed of the glass fiber ropes has good fireproof performance; by adopting the structure, the wear-resistant and tensile properties of the whole cable can be improved, meanwhile, the conductor is formed by twisting five types of tinned flexible
