[0002] In rodless oil production equipment, the submersible motor of the submersible electric pump unit operates downhole in the oil well, at a depth of 1 to several kilometers above the ground. It is exposed to the oil well medium and pressure environment, which is harsh. The lead cable head connects to the downhole motor and must withstand high temperature, high pressure and high corrosion. Therefore, the manufacturing quality of the lead cable head directly affects the reliability and service life of the entire submersible electric pump unit.
