Inorganic mineral insulation isolation type B1-level flame-retardant high-temperature fire-resistant cable

The invention discloses an inorganic mineral insulation isolation type B1-level flame-retardant high-temperature fire-resistant cable which comprises an isolation layer, the inner surface of the isolation layer is wrapped with an inorganic mineral insulation layer, the interior of the inorganic mineral insulation layer is wrapped with wires, gaps defined by the wires are wrapped with insulation filling strips, and the insulation filling strips are arranged in the gaps. An insulating protective layer is arranged on the outer surface of the wire, a flame-retardant layer is wrapped in the insulating protective layer, and a copper core is wrapped in the flame-retardant layer. According to the inorganic mineral insulation isolation type B1-level flame-retardant high-temperature fire-resistant cable, in the daily use process, the insulation protection capacity is enhanced, the situation that fire breaks out due to the fact that the temperature of the wires is too high in the long-time use process of the cable is ef
