[0009] Further, a plurality of through holes are uniformly provided on the butt joint strip and the connecting strip.

[0010] By adopting the above technical solution, the butt joint strip and the connecting strip in the present application are made of flexible material, and by uniformly providing through holes on the butt joint strip and the connecting strip, there is more twisting space when bending.

[0011] Further, a flexible filler is arranged between the sealing layer and the cable shell, and the flexible filler is uniformly filled between the sealing layer and the cable shell.

[0013] Further, a sealing filler is arranged between the sealing layer and the insulation layer.

[0014] Further, the flexible filler and the sealing filler are both made of a high-molecular elastic material.

[0016] Further, the cable shell is fixedly provided with a corrosion-resistant layer, and the corrosion-resistant layer wraps the cable shell.

[0017] By adopting the technical scheme, the corrosion-resistant layer can reduce the corrosion of the cable shell by the outside world.

[0018] Further, the outer side of the corrosion-resistant layer is coated with an insect-resistant paint.

[0019] By adopting the technical scheme, the insect-resistant paint can reduce the damage of underground pests to the cable.

[0020] In summary, the present application has the following beneficial technical effects: by arranging the fixed connecting strips between the insulation layers, when the wind power cable is twisted in a complex environment, the connecting strips can effectively provide additional tension support for the insulation layers. This design significantly enhances the structural stability of the cable during twisting, reduces internal stress caused by twisting, and prolongs the service life of the cable. The cable shell and the insulation layer have a movable space, which allows the cable to have flexibility when twisted, reducing the direct bending of the conductive cable and the insulation layer. This not only protects the electrical structure inside the cable, but also avoids damage to the cable caused by repeated bending, improves the reliability and durability of the cable, and ensures electrical isolation between the conductive cables, preventing current leakage and short circuit. At the same time, the close cooperation of the connecting assembly and the insulation layer further enhances the electrical stability of the cable, making the cable more efficient and safe in transmitting electrical energy.

[0024] The application will be further described in detail below with reference to the accompanying drawings.

[0025] Embodiment, refer to Figure 1 And Figure 2 , high-efficiency torsion-resistant wind power cable, comprising a cable shell 1 and a plurality of groups of conductive cables 2 inside the cable shell 1, and an insulation layer 21 arranged outside each of the conductive cables 2 for wrapping the conductive cable 2, and a connecting assembly arranged between the insulation layers 21. The connecting assembly comprises a connecting strip 23 fixedly arranged between the insulation layers 21. When the wind power cable is twisted, the connecting strip 23 between the insulation layers 21 can additionally provide tension for the insulation layers 21, and there is a movable space between the cable shell 1 and the insulation layer 21 in the wind power cable, so that the internal cable is reduced to bend.

[0026] In this embodiment, a sealing layer 11 is arranged inside the cable shell 1 for wrapping the plurality of insulation layers 21, and the connecting assembly comprises a butt joint strip 22 arranged between the sealing layer 11 and the insulation layer 21. The arrangement of the butt joint strip 22 can improve the connectivity between the insulation layer 21 and the sealing layer 11.

[0027] In this embodiment, a plurality of through holes 220 are uniformly arranged on the butt joint strip 22 and the connecting strip 23. The butt joint strip 22 and the connecting strip 23 in this application are made of flexible material, and by uniformly arranging the through holes 220 on the butt joint strip 22 and the connecting strip 23, a larger twisting space can be provided when bending.

[0028] In this embodiment, a flexible filler 31 is arranged between the sealing layer 11 and the cable shell 1, and the flexible filler 31 is uniformly filled between the sealing layer 11 and the cable shell 1. The arrangement of the flexible filler 31 can ensure that the cable shell 1 can reduce the influence of the internal sealing layer 11 when twisted.

[0029] In this embodiment, a sealing filler 3 is arranged between the sealing layer 11 and the insulation layer 21. The flexible filler 31 and the sealing filler 3 are both made of high-molecular elastic material.

[0030] In this embodiment, the arrangement of the sealing filler 3 can further protect the internal sealing layer 11 and the insulation layer 21 when the external cable shell 1 is twisted. The cable shell 1 is fixedly provided with an anticorrosive layer 10, and the anticorrosive layer 10 wraps the cable shell 1.

[0031] In this embodiment, the corrosion-resistant layer 10 can reduce the corrosion of the cable shell 1 by the external environment. The outer side of the corrosion-resistant layer 10 is coated with an insect-resistant coating. The setting of the insect-resistant coating can reduce the damage of underground pests to the cable.

[0032] Specific use process: The cable shell 1 serves as a protective layer, providing physical protection and support for the internal conductive cables 2. The multiple sets of conductive cables 2 are responsible for transmitting electrical energy, which is the core functional part of the cable.

[0033] Each set of conductive cables 2 is carefully provided with an insulating layer 21 on the outer side to ensure that the current does not leak during transmission, while providing the necessary electrical isolation. These insulating layers 21 not only enhance the safety of the cable, but also reduce the mechanical stress of the cable during twisting through specific design.

[0034] In order to further enhance the twisting resistance of the cable, connection components are ingeniously arranged between the insulating layers 21. These connection components include connection strips 23 fixedly arranged between the insulating layers 21, which can provide additional tension support for the insulating layers 21 when the cable is twisted, effectively reducing the bending degree of the insulating layers 21 and the conductive cables 2, and prolonging the service life of the cable.

[0035] In addition, the cable shell 1 is also provided with a sealing layer 11 inside, which is used to wrap multiple sets of insulating layers 21 and provide additional environmental protection. The sealing layer 11 is connected with the insulating layer 21 through the butt joint strip 22, which not only improves the connectivity between the two, but also provides more twisting space for the cable when it is twisted through the design of uniformly opened through holes 220, further enhancing the flexibility of the cable.

[0036] In order to further optimize the structure and performance of the cable, a flexible filler 31 is filled between the sealing layer 11 and the cable shell 1. This filler is uniformly distributed between the two, effectively reducing the impact of the cable shell 1 on the internal sealing layer 11 when it is twisted, ensuring the overall stability and durability of the cable.

[0037] At the same time, a sealing filler is also arranged between the sealing layer 11 and the insulating layer 21, which is made of high molecular elastic material and can further protect the internal sealing layer 11 and insulating layer 21 when the cable is twisted, preventing damage caused by mechanical stress.

[0038] The outer side of the cable shell 1 is fixedly provided with a corrosion-resistant layer 10, which is made of special materials and can effectively reduce the corrosion of the cable shell 1 by the external environment. In order to further protect the cable, the outer side of the corrosion-resistant layer 10 is also coated with an insect-resistant coating, which can effectively prevent underground pests from gnawing and damaging the cable, ensuring the long-term stable operation of the cable in complex environments.

[0039] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
