Zusammenfassung:The invention discloses a temperature monitoring type submersible oil pump cable. A pressure gauge cable core comprises first conductors, a polypropylene insulation layer coats outside each first conductor, and a first polypropylene protection layer, a bearing armored steel wire layer and a polypropylene outer jacket sequentially coat outside the three first conductors after the first conductors are twisted; a compensation cable core comprises second conductors, a polypropylene insulation layer coats outside each second conductor, and a silicone rubber outer jacket coats outside the two second conductors after the two second conductors are twisted; and a submersible oil pump cable core comprises third conductors, and a polypropylene insulation layer, a second polypropylene protection layer and an oil-resistant cushion layer sequentially coat outside the third conductors. In the temperature monitoring type submersible oil pump cable, a cable special for an underground flow measurement system and a thermocoupling compensation guide line are added on the basis of the original submersible oil pump cable, dual protection on an electric motor in an oil well is achieved, the service efficiency of the electric motor of a submersible oil pump can be greatly improved, and the service life of the electric motor also can be prolonged.
