The invention discloses a high-performance flexible fire-resistant cable, which comprises a conductor, wherein the conductor is sequentially coated with a mica tape refractory layer, a special polymer material insulating layer, an aluminum foil mica paper layer and an outer sheath layer from inside to outside. The high-performance flexible fire-resistant cable has the advantages that a low-smoke halogen-free sheath material is taken as the outer sheath layer, aluminum foil mica paper is taken as a first refractory layer, the special polymer material insulating layer with the flame retardant property is taken as a second refractory layer and a mica tape is taken as a third fireproof layer, so that the fire resistance of the cable is greatly improved due to presence of protection of the three refractory layers; the condition that the cable can tolerate 950 DEG C for 3 hours is ensured; the high-performance flexible fire-resistant cable has spraying and vibrating fire-resistant conditions; the production process
