The utility model relates to a cable-type thermocouple temp.-measuring electric power cable, belonging to the technical field of the cable. The cable is provided with a temperature measurement element comprising a metallic oxide semi-conducting coating, a colomony outer conductor and a polytetrafluoroethylene insulation layer which are arrnanged in sequence on the outer surface of a copper inner conductor, and three power cables comprising a crosslinked semiconductor inner shielding layer, a crosslinked polyethylene insulation layer, a crosslinked semiconductor outer shielding layer, copper strip winding coating shielding layer which are respectively on the outer surface of a pressing twist copper wire conductor. The temperature measurement element is coated and twisted in the middle of the triple line core of three power cables. The utility model has reasonable and simple structure, easy production and manufacture, low cost and favorable operation performance. The temperature measurement element can achieve the purpose of the inductive high-temperature when the cable excesses the load and the temperature rises. The utility model is propitious to make the on-line detection for the cable temperature, and the user can make awareness of the temperature change of the cable at any moment, discover the cable fault and make an alarm in time, remind the work staff to make maintenance, and avoid the occurrence of failure. The utility model has very favorable popularization and application value.
