Insulated self-temperature-measuring cable

The invention relates to the field of cables, in particular to an insulated self-temperature-measuring cable. The cable comprises a cable core used for transmitting electric power and/or a signal andcoated with an insulated layer, a temperature-sensing optical fiber used for monitoring the temperature of the cable, and a flame-retardant layer coating the cable core and the temperature-sensing optical fiber and used for protecting the cable core and the temperature-sensing optical fiber; a space between the cable core and the temperature-sensing optical fiber in the flame-retardant layer is filled with a flame-retardant material; and the flame-retardant material is used for fixing the cable core and the temperature-sensing optical fiber in the flame-retardant layer, and carrying out flame-retardant protection on the cable core and the temperature-sensing optical fiber. The cable provided by the invention has good fireproof performance; normal power supply still can be ensured under thecondition that a fire occ
