Description

Technical Field

[0001] The utility model belongs to the field of submersible pump cables and relates to a submersible pump cable design and processing technology, in particular to a tensile and high temperature resistant flat submersible pump cable. Background Art

[0002] Submersible pump cables are mainly used in submersible pump systems to transmit electrical energy and control signals. Limited by the narrow space of oil well casing, submersible pump power cables are usually flat.

[0003] The patent with authorization announcement number: CN 213424617 U discloses a tensile and high-temperature resistant flat submersible pump cable, including a vertical rod, a regulating valve and a connecting frame. A through hole is provided on the surface of the left end opening direction of the protective cover, and the through hole is fixedly connected to the opening side of the airbag. A through hole is provided on the surface of the right end opening direction of the protective cover. The internal circuit of the guide rod is fixedly connected to one end of the connecting guide plate, and the guide plate is placed in the protective cover. The other end of the guide plate is fixedly connected to the copper core, and the outer wall of the copper core is in conflict with the inner wall of the cover.

[0004] The above scheme increases the service life of the cable by filling the protective cover with inert halogen gas. Filling the inert gas requires additional equipment and processes, and the cost of the inert gas itself is also high, so it will increase the cost of cable manufacturing and maintenance, and also increase the difficulty of cable maintenance. In addition, the flat design is generally adopted due to the small space of the oil well. The above scheme installs a regulating valve and an air bag on the inert gas protective cover, which is not conducive to space utilization. Utility Model Content

To this end, the utility model proposes a tensile-resistant and high-temperature-resistant flat submersible pump cable, which solves the problem of increasing the manufacturing cost and maintenance difficulty of the cable by filling the cable protective sheath with inert halogen gas to increase the service life of the cable in the prior art.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a tensile-resistant and high-temperature-resistant flat submersible pump cable is proposed, comprising a copper core conductor, an insulating layer, a sheath layer, a metal shielding layer, a waterproof layer, and a filling layer; the copper core conductor is composed of a plurality of strands of finely twisted high-purity copper wires, an insulating layer is fixedly connected to the outside of the copper core conductor, a sheath layer is wound around the outside of the insulating layer, a metal shielding layer is arranged on the outside of the sheath layer, a filling layer is filled between the sheath layer and the metal shielding layer, and a waterproof layer is fixedly installed on the outside of the metal shielding layer.
