The invention provides an intelligent mineral insulated cable, which comprises a cable inner core structure and a cable sheath structure, wherein the cable inner core structure comprises a distributed optical fiber temperature sensing system, an optical fiber, a PBT sheath, a copper conductor and a mineral insulating layer, the cable sheath structure sequentially comprises a halogen-free low-smoke flame-retardant polyolefin inner sheath, a quartz net layer, a mica tape layer, a ceramic polyolefin sheath, a nylon sheath layer and a halogen-free low-smoke flame-retardant polyolefin sheath layer from inside to outside, and filling is arranged between the cable inner core structure and the cable sheath structure. The intelligent mineral insulated cable has the beneficial effects that the intelligent mineral insulated cable can transmit optical signals while transmitting power, can intelligently detect physical quantities such as stress, temperature, liquid flow rate, sound pressure, hydraulic pressure and magnetic field around the mineral insulated cable along with the change of working conditions, enables the mineral insulated cable to be in an optimal working state, and adopts the ceramic polyolefin sheath and the nylon sheath, so that the cable has the performance of being resistant to bite of rats and ants, fireproof, flame-retardant, green, environment-friendly and the like.
