The utility model relates to an intelligent mineral medium-voltage fireproof self-monitoring cable, which comprises insulating phase wire cores, optical fiber units, a filling layer, a wrapping fireproof layer, a protective layer and an outer sheath, wherein the number of the insulation phase wire cores is multiple, the filling layer is filled in gaps among the insulation phase wire cores, the wrapping fireproof layer is wrapped outside the filling layer, the protection layer is wrapped outside the wrapping fireproof layer, the outer sheath is wrapped outside the protection layer, and the optical fiber units are distributed in a middle gap formed after the insulation phase wire cores are stranded and an external gap between the adjacent insulation phase wire cores. Compared with the priorart, according to the utility model, the cable can still be used when a medium-voltage cable is in a fire, gas and smoke generated by the fire are non-toxic and pollution-free, and the time and intelligent monitoring requirem
