Among them, the material of the second elastic protective layer 5 is preferably polyurethane. The buoyancy layer 6 facilitates the shore-based cable of the present application to have a certain floating property. The material of the buoyancy layer 6 is preferably aramid, and it also facilitates to increase the tensile property of the shore-based cable of the present application. The third elastic protective layer 7 is used as the outer sheath of the shore-based cable of the present application. Specifically, the extrusion extrusion method can be adopted. The material of the third elastic protective layer 7 is preferably polyurethane, which is convenient to increase the wear resistance, oil resistance, high and low temperature resistance of the shore-based cable of the present application, thereby increasing the service life. In summary, the first elastic protective layer 2 of the present application is used to wrap a plurality of power cores 1, which facilitates the plurality of power cores 1 and the first elastic protective layer 2 to exert a good supporting effect on the plurality of control cores 4 and prevent the plurality of control cores 4 from breaking, and the second elastic protective layer 5 is used to wrap the plurality of control cores 4 to facilitate preventing the plurality of control cores 4 from bulging.

The second elastic protective layer 5 is wrapped outside the braided shielding layer 33. Specifically, the reinforced braided layer 31 is used to increase the tensile property of the shore-based cable of the present application. The extrusion extrusion method is specifically adopted to enable the fourth elastic protective layer 32 to wrap the reinforced braided layer 31 to facilitate fixing the reinforced braided layer 31.
