The anti-corrosion tightening layer 2 is wrapped and fixed in the outer wall gap of the cable core 1, and the material of the anti-corrosion tightening layer 2 is chlorofilament cloth. At the same time, the chlorofilament cloth itself has corrosion resistance, water resistance, chemical resistance, corrosion resistance, non-flammability and good electrostatic insulation, which is beneficial to the cable core 1 to play the role of corrosion protection and tightening the cable core 1 to prevent loose strands, and the electrostatic insulation can be used to prevent the outer wall of the cable from carrying negative charge.

The material of the metal shielding layer 3 is a copper-plastic composite tape, and the thickness of the metal shielding layer 3 is 0.16mm. The metal shielding layer 3 is formed by a copper-plastic composite tape with a corrosion resistance level of 7.5. The copper-plastic composite tape has the function of shielding external electromagnetic interference and anti-corrosion, thereby improving the overall corrosion resistance of the cable. At the same time, the cable can be transmitted under electromagnetic interference to prevent electromagnetic influence on the transmission effect of the cable.

[0023] See also Figure 1 , Figure 2 and Figure 5The outer wall of the metal shielding layer 3 is extruded and fixed with a protective layer 4, the material of the protective layer 4 is polytetrafluoroethylene plastic, the thickness of the protective layer 4 is 1.0mm, the protective layer 4 is extruded and coated on the outer wall of the metal shielding layer 3 by a 300-330°C extruder, and the extrusion thickness is 1.0mm, the protective layer 4 formed by polytetrafluoroethylene plastic has a good anti-corrosion effect on the cable core 1, the cable core 1 includes a plurality of conductors 11, the conductors 11 are formed by tinned soft copper, the tinned soft copper itself has excellent electrical properties, and can also resist strong acid and corrosion, thereby enhancing the corrosion resistance of the cable core 1, the outer walls of the conductors 11 are respectively overlapped and wrapped with anti-corrosion insulating layers 12, and the outer wall of the anti-corrosion insulating layer 12 and the anti-corrosion tightening layer 2 are filled with an anti-corrosion filling layer 13, the anti-corrosion filling layer 13 wraps the conductor 11 and the anti-corrosion insulating layer 12 to form a cylindrical shape. The material of the anti-corrosion filling layer 13 is polypropylene fiber rope. The anti-corrosion filling layer 13 is formed by the polypropylene fiber rope. The polypropylene fiber rope itself is wear-resistant, acid-resistant, alkali-resistant, and corrosion-resistant, and improves the corrosion resistance of the cable core 1. The anti-corrosion filling layer 13 is twisted together with the anti-corrosion insulating layer 12 and the anti-corrosion filling layer 13 to form the cable core 1. The anti-corrosion insulating layer 12 and the anti-corrosion filling layer 13 protect the conductor 11. When the cable is buried in acidic and alkaline underground, the corrosion resistance of the anti-corrosion insulating layer 12 and the anti-corrosion filling layer 13 allows the conductor 11 to be used for a longer time, preventing the acidic and alkaline geology from corroding the conductor 11 and affecting its use.

[0024] See also Figure 3 , Figure 4 and Figure 5The anti-corrosion insulation layer 12 includes an inner anti-corrosion insulation layer 121 and an outer anti-corrosion insulation layer 122. The inner anti-corrosion insulation layer 121 is overlapped and wrapped and fixed on the outer wall of the conductor 11. The overlap rate of the inner anti-corrosion insulation layer 121 is 50% of the width of the inner anti-corrosion insulation layer 121. The inner anti-corrosion insulation layer 121 insulates the conductor 11. At the same time, the overlap rate of the overlapping wrapping is set to 50% of the width of the inner anti-corrosion insulation layer 121 to achieve comprehensive sealing of the conductor 11, which plays a role in protection and insulation. The outer anti-corrosion insulation layer 122 is overlapped and wrapped and fixed on the outer wall of the inner anti-corrosion insulation layer 121.

The overlapping rate of the overlapping layer 122 is 20% of the width of the outer anti-corrosion insulating layer 122. The outer anti-corrosion insulating layer 122 plays a secondary insulating and tightening role. The outer anti-corrosion insulating layer 122 tightens the inner anti-corrosion insulating layer 121 and the conductor 11, so that the inner anti-corrosion insulating layer 121 is tightly fitted with the conductor 11 to prevent gaps, thereby providing good protection for the conductor 11.

[0026] The difference from Example 1 is that the overlapping and wrapping directions of the inner anti-corrosion insulation layer 121 and the outer anti-corrosion insulation layer 122 of the anti-corrosion insulation layer 12 are opposite. After the inner anti-corrosion insulation layer 121 is overlapped and wrapped on the outer surface of the conductor 11, the outer anti-corrosion insulation layer 122 is reversely overlapped and wrapped and fixed on the outer surface of the inner anti-corrosion insulation layer 121, which is beneficial for the outer anti-corrosion insulation layer 122 to tighten the inner anti-corrosion insulation layer 121. At the same time, the overlapping lines of the outer anti-corrosion insulation layer 122 are opposite to and cross the lines of the inner anti-corrosion insulation layer 121, which increases the fit between the inner anti-corrosion insulation layer 121 and the outer anti-corrosion insulation layer 122, and prevents sliding between the inner anti-corrosion insulation layer 121 and the outer anti-corrosion insulation layer 122.

At the same time, the overlap rate of the overlapped wrapping of the inner anti-corrosion insulation layer 121 is 50% of the width of the inner anti-corrosion insulation layer 121. After completion, an outer anti-corrosion insulation layer 122 with a thickness of 0.2 mm is overlapped and wrapped on the outer wall of the inner anti-corrosion insulation layer 121. At the same time, the overlap rate of the overlapped wrapping of the outer anti-corrosion insulation layer 122 is 20% of the width of the filament and the overlapped part is staggered with the overlapped part of the inner anti-corrosion insulation layer 121. The inner anti-corrosion insulation layer 121 is tightened, and then a polypropylene fiber rope is selected to wrap the outer wall of the outer anti-corrosion insulation layer 122 to form an anti-corrosion filling layer 13. The anti-corrosion filling layer 13 and the conductor 1 1 and the anti-corrosion insulating layer 12 are twisted to form a cable core 1, and then the outer wall of the cable core 1 is indirectly wrapped with a chloroprene cloth insulating cloth with a width of 15mm and a thickness of 0.1mm to form an anti-corrosion tightening layer 2, and the gap rate of the gap wrapping of the anti-corrosion tightening layer 2 is 100% of the width of the anti-corrosion tightening layer 2.

Finally, the polytetrafluoroethylene plastic is extruded and coated on the outer wall of the metal shielding layer 3 by an extruder at 300-330°C, and the extrusion thickness is 1.0mm. After the polytetrafluoroethylene plastic is cooled, a protective layer 4 is formed to complete the production of the cable.
