The working conditions in the well are severe, and the well is often in environments with strong corrosivity such as high temperature, high pressure, and oil-gas-containing environment. The power cable of the submersible pump can be divided into a round power cable and a flat power cable. Due to the limited narrow space of the oil well casing, the power cable of the submersible pump is mainly flat. Since the flat cable has an asymmetric structure, magnetic hysteresis loss is caused by electromagnetic induction generated by unbalance of a magnetic field during power transmission, and the cable generates heat. Circular cables are preferred where well casing sizes permit. The circular cable with symmetrical structure has the advantages of uniform distribution of generated electromagnetic fields, small mutual interference, good electromagnetic compatibility and convenient taking-up and paying-off when laid in an oil well.
The cable of the submersible pump has different use occasions and different use characteristics and requirements on the cable of the submersible pump. In particular, in the oil field and other occasions with strict requirements on the use of the cable, the cable is required to have good electrical property and mechanical property, and also has high performance such as adaptability to complex environment. For example: if the viscosity of the oil is too high, chemical agents need to be added for dilution; the long-term use of the submersible pump can accumulate a large amount of oil dirt to influence the normal work of the submersible pump. The common submersible pump cable has the following technical problems: the function is single, only electric energy can be transmitted, and the diluting and cleaning functions cannot be completed; the cable has the advantages of simple structure, poor mechanical resistance, weak tensile resistance, easy damage during laying, incapability of meeting the use requirement on the adaptability of a complex environment, and shortened service life after the cable is damaged by external force, vibration and the like.

The invention innovatively adopts a composite structure of the cable and the stainless steel tube, increases the functions and the cost performance of the cable, improves the tensile strength of the cable, and increases the environmental resistance of the cable by adopting the outer steel tube sheath layer.
However, in practical use, the technical scheme still has many defects, for example, when the cable is used in an oil well for a long time under the conditions of high temperature and high pressure, the compressive strength of the cable cannot be guaranteed, and the cable is easy to damage and has a short service life.
