This can cause moisture to penetrate the cable and lead to faults such as short circuits. Marine cables are subject to significant tension and pressure during use. However, some existing cables exhibit poor tensile strength and are prone to breakage or damage when subjected to external forces, compromising their performance. Utility Model Content

[0024] The utility model provides Figure 1-3The illustrated embodiment shows a shipboard cable having good water-blocking and tensile-resistant effects, comprising, from outside to inside, an outer sheath 1, a first water-blocking layer 2, a shielding layer 3, a second water-blocking layer 4, and a wrapping layer 5. The wrapping layer 5 comprises a plurality of cable cores 6, which are filled with a first filling rope 7 and a plurality of second filling ropes 8. The cable core 6 comprises an inner sheath 6.1 and a third water-blocking layer 6.2 located within the inner sheath 6.1. The third water-blocking layer 6.2 comprises two cores, the third water-blocking layer 6.2 being filled with water-blocking glue 6.5. The core comprises a conductor 6.4 and an insulating layer 6.3 covering the conductor 6.4. The first water-blocking layer 2 is formed by longitudinally wrapping an aluminum-plastic composite tape, the second water-blocking layer 4 is woven with water-blocking yarn, the third water-blocking layer 6.2 is formed by longitudinally wrapping an aluminum-plastic composite tape, the first filling rope 7 is formed by vulcanized rubber strips, and the second filling rope 8 is formed by water-blocking filling ropes.

[0025] The outer sheath 1 is made of polyvinyl chloride. The shielding layer 3 is braided copper wire. The wrapping layer 5 is a polyester tape wrapping layer. The inner sheath 6.1 is made of polyvinyl chloride. Multiple cable cores 6 are distributed in an annular shape with equal spacing. The multiple cable cores 6 surround the first filling cord 7. A second filling cord 8 is provided between the wrapping layer 5 and two adjacent cable cores 6.

[0026] Working Principle: The marine cable in this application utilizes multiple layers of water-blocking layers, water-blocking filler ropes, and water-blocking adhesive to significantly enhance its water-blocking properties, effectively preventing moisture from penetrating the cable and causing short circuits. Furthermore, the inclusion of vulcanized rubber strips and water-blocking filler ropes ensures uniform stress distribution when subjected to external forces, enhancing the cable's tensile strength.

[0027] During the specific preparation process, multiple cable cores are first distributed in a circular shape with equal spacing and surrounded by vulcanized rubber strips. The cable cores and vulcanized rubber strips are then tightly wrapped with polyester tape, and water-blocking filling rope is filled between two adjacent cable cores and the polyester tape to improve the cable's tensile strength and water-blocking performance. A second water-blocking layer is then braided with water-blocking yarn over the polyester tape wrapping to improve the cable's water-blocking effect. A shielding layer is then braided with copper wire over the second water-blocking layer to improve the cable's shielding effect. An aluminum-plastic composite tape is then longitudinally wrapped over the shielding layer to form a first water-blocking layer, further improving the cable's water-blocking effect. Finally, an outer sheath is extruded over the first water-blocking layer to protect the cable's internal structure.
