[0022] As a technical optimization solution of the present invention, the protective layer 9 includes a corrosion-resistant layer 901 , and the outer surface of the corrosion-resistant layer 901 is fixedly connected to a wear-resistant layer 902 .

[0023] In this embodiment, by providing the corrosion-resistant layer 901, the corrosion resistance of the cable can be improved, and by providing the wear-resistant layer 902, the wear resistance of the cable can be improved.

[0024] As a technical optimization solution of the present invention, the inner surface of the corrosion-resistant layer 901 is fixedly connected to the connection point of the armor layer 8, and the material of the corrosion-resistant layer 901 is polyetheretherketone.

[0025] In this embodiment: the material of the corrosion-resistant layer 901 is set to polyetheretherketone.

[0027] In this embodiment: the material of the insulating layer 10 is set to polytetrafluoroethylene, which is also known as Teflon. It is a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It has excellent heat resistance and cold resistance and can be used for a long time at -180 to 260°C.

It also has good wear resistance, impact resistance, corrosion resistance, light resistance and other excellent properties, which can effectively improve the wear resistance of the cable. By setting the material of the shielding layer 6 to aluminum foil Mylar, aluminum foil Mylar is based on metal aluminum foil, which is bonded with polyester tape after backing with adhesive.
