[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 The deep-sea marine engineering equipment uses a UV-resistant, oil-sludge-resistant, highly flame-retardant, rodent-proof cable, offering two technical solutions:

[0021] The first embodiment includes a cable body 1, which has at least three sets of cable core structures inside. A support component 7 is provided between each pair of cable core structures. A second wrapping layer 9 is wrapped around the outside of each cable core structure. The support components 7 are supported within the cable core structure and the second wrapping layer 9. A filling layer 8 fills the cavity between the cable core structure, the support components 7, and the second wrapping layer 9. Each cable core structure includes two conductor structures and a first wrapping layer 6. Each conductor structure includes two conductors 2. A fire-resistant layer 3 is provided outside each conductor 2, and an insulation layer 4 is provided outside the fire-resistant layer 3. The first wrapping layer 6 is located outside the two conductor structures, and a separate shielding layer 5 is provided between the first wrapping layer 6 and the two cable cores. The second wrapping layer 9 has, in sequence, a total shielding layer 10, an inner lining layer 11, a corrugated armor layer 12, and an outer sheath 13. The fire-resistant layer 3 is formed by wrapping mica tape. The insulation layer 4 is made of cross-linked polyethylene. The olefin filling layer 8 is filled with halogen-free flame-retardant rope, the second wrapping layer 9 is wrapped with halogen-free flame-retardant tape, the total shielding layer 10 is longitudinally wrapped with aluminum-plastic composite tape, the inner lining layer 11 is formed by extruding halogen-free flame-retardant oxygen-barrier material, the corrugated armor layer 12 is formed by corrugated stainless steel armor, and the outer sheath 13 is a UV-resistant and rodent-resistant halogen-free flame-retardant sheath material. This sheath material effectively blocks or absorbs ultraviolet rays by adding ultraviolet absorbers or reflectors to the material, thereby extending the service life of the sheath; it also contains ingredients that pests dislike, such as special additives or odorants, which can repel or kill pests; at the same time, the halogen-free flame-retardant sheath material does not produce toxic hydrogen halide gas when burning, making it safer for the environment and users. The flame-retardant effect is achieved by adding special flame retardants, which can decompose at high temperatures to produce a large amount of water vapor, carbon dioxide and other inert gases, thereby preventing combustion.

[0022] The cable body is equipped with a sub-shielding layer 5 and a total shielding layer 10 to ensure stable power transmission. At the same time, the outer sheath 13 is made of UV-resistant, rodent-proof, halogen-free, and flame-retardant material, which can effectively resist UV rays and prevent rodents and insects, thus benefiting the long-term use of the cable.

[0023] The second embodiment differs from the first embodiment in that the support component 7 includes two first arc-shaped portions 71 and a second arc-shaped portion 72. The two first arc-shaped portions 71 and the second arc-shaped portion 72 are fixedly connected by a connecting portion 73. The two first arc-shaped portions 71 respectively contact the outside of two adjacent first wrapping layers 6, and the second arc-shaped portion 72 contacts the inside of the second wrapping layer 9.

[0024] A support component 7 is installed on the outside of the cable core structure to support the cable core structure, thereby ensuring its stability and making it less prone to deformation inside the cable.

[0025] During manufacturing, the support component 7 is installed on the outside of the cable core structure, the two second arc-shaped parts 72 respectively contact the outside of the two cable core structures, and the remaining gaps are filled with the filling layer 8. The conductor 2 is provided with a fire-resistant layer 3 for fire prevention, and the cable interior is shielded by the sub-shielding layer 5 and the total shielding layer 10. The cable is protected by the outer sheath 13 to prevent rodents and ants from damaging the cable surface.
