High-temperature-resistant fireproof special cable for spaceflight

The invention discloses a high-temperature-resistant fireproof special cable for spaceflight, and belongs to the technical field of cables. The high-temperature-resistant fireproof special cable comprises a strong current cable, a weak current cable, a first insulating layer, a first fireproof layer, a waterproof layer, a wrapping layer, a first shielding layer and an outer sheath, wherein the strong current cable and the weak current cable are twisted together to form a strong and weak cable; the first insulating layer wraps the outer side of the strong and weak cable; and the first fireprooflayer wraps the outer side of the first insulating layer. Strong current and weak current can be switched on at the same time, the installation space is saved, the installation of the cables on the aviation spacecraft does not need to be strictly planned, the installation time of the cables is greatly shortened, and the installation efficiency of the cables is improved; and multi-layer fireprooffunctions are achieved, so
