[0002] Marine communication cables are electrical wires and cables used in the design of ships and offshore structures. They are used for various functions such as power, lighting, control, and communication transmission. Ships have a large number of electronic devices, and electromagnetic interference may be generated during communication transmission, affecting the normal operation of other equipment.

[0004] The aforementioned shielded cable can prevent conductors from twisting and shifting under external pressure. However, during communication, electromagnetic interference can easily occur between multiple cores, making it difficult to shield individual cores.

Through the tin foil shielding layer, individual wire cores can be shielded to avoid signal interference between multiple wire cores.
[0015] 2) This communication cable, by setting up protective components, with tinned copper wire braided on the outside of the outer filler, further reduces interference between signals inside and outside the core and improves the overall signal shielding effect.

The outer surface of the tin foil shielding layer 7 is coated with an outer insulation layer 8, and the outer surface of the inner filler 4 and the four wire cores 5 is filled with an outer filler 9.
[0025] The four wire cores 5 are arranged in a ring around each other, and the four wire cores 5 are spirally wound around the outside of the inner filler 4. By spirally winding the wire cores 5, metal fatigue can be reduced during cable bending.

The outer wall of the outer insulation layer 8 is in contact with the outer wall of the inner filler 4 and the inner wall of the outer filler 9, respectively. The tin foil shielding layer 7 is used for communication shielding of a single wire core 5 to avoid signal interference between multiple wire cores 5.
[0027] Specifically, the inner filler 4 and the outer filler 9 are composed of foamed polyethylene with different degrees of softness. The inner filler 4 supports the four wire cores 5 and provides a suitable buffer shrinkage effect. The tin foil shielding layer 7 shields the individual wire cores 5 to avoid signal interference between multiple wire cores 5. The outer filler 9 fixes the four wire cores 5.

The thickness of the silicone rubber layer 11 is greater than the thickness of the waterproof injection layer 12. The tin-plated copper wire weave layer 10 is used for overall signal shielding to reduce interference from internal and external signals to the wire core 5.
[0031] The silicone rubber layer 11 and the outer sheath 13 are bonded together by a waterproof adhesive layer 12. The thickness of the outer sheath 13 is greater than the thickness of the silicone rubber layer 11. The silicone rubber layer 11 is used to provide overall cushioning for the cable, and the waterproof adhesive layer 12 improves internal waterproofing.
[0032] Specifically, the tinned copper wire weave layer 10 shields the internal and external signals, reducing interference to the wire core 5. The silicone rubber layer 11 has good high temperature resistance and insulation, providing overall buffering for the cable. The waterproof injection layer 12 fills the damaged parts of the outer sheath 13, improving the internal waterproof effect.
[0033] In actual operation, the reinforcing core 1 is used to enhance the overall tensile strength, the wire core 5 is used for communication transmission, and the outer sheath 13 provides overall protection for the cable.
[0034] When individual shielding is performed, the inner filler 4 and the outer filler 9 are composed of foamed polyethylene with different degrees of softness. The inner filler 4 supports the four wire cores 5 and provides a suitable buffer shrinkage effect. The tin foil shielding layer 7 is located outside the wire cores 5. The wire cores 5 are isolated from each other by the inner insulation layer 6 and the outer insulation layer 8. The tin foil shielding layer 7 shields the individual wire cores 5 to avoid signal interference between multiple wire cores 5. The outer filler 9 fixes the four wire cores 5.
[0035] When providing protection, the tinned copper wire braid 10 is woven around the outside of the outer filler 9 to shield the signals inside and outside the wire core 5, reducing interference to the wire core 5.
