[0003] The wide application of electric ships not only helps reduce environmental pollution but also lowers operating costs. However, their charging problem, especially the power connection after docking, has become an urgent issue to be solved. Currently, most electric ships are charged by connecting to shore power through ordinary cables after docking. However, this charging method faces severe challenges in the special environment of ports.

This not only brings great inconvenience to ship operators but also makes the cables vulnerable to damage during frequent bending and dragging, further shortening their service life. In addition, the insulation layer and sheath materials of ordinary cables are extremely prone to corrosion under the long-term erosion of salt spray and moisture, resulting in a decline in the insulation performance of the cables and even potentially causing safety accidents such as short circuits, seriously threatening the safety of ships and personnel.

[0024] Embodiment 1

[0025] See Figure 1As shown in the figure, this embodiment provides a marine new energy charging pile cable, which includes: at least one conductive component 100; a waterproof component 300, the waterproof component 300 includes at least two waterproof belts 310, at least two of the waterproof belts 310 are connected to each other in a braided structure, and a hollow accommodation cavity 330 is formed by enclosing inside thereof, and at least one of the conductive components 100 is disposed in the accommodation cavity 330; at least one water-repellent filling member 200, at least one of the water-repellent filling members 200 is disposed in the accommodation cavity 330, and is simultaneously abutted against the inner wall of the waterproof component 300 and the conductive component 100.

[0026] The marine new energy charging pile cable in this embodiment provides waterproof protection for the internal conductive component 100 through the waterproof component 300, enabling it to greatly slow down the erosion of port salt spray and moisture, and thus achieving the purpose of extending the service life. At the same time, the water-repellent filling member 200 can improve the overall strength and stability of the cable. It reduces the relative movement between the conductive components 100 to reduce friction vibration interference, and can also further improve the waterproof effect of the cable. Compared with conventional cables, this application has significant advantages such as good waterproof effect, high support strength, long service life, and stable operation effect, and can be widely applied to high-humidity environments such as ships and docks.

[0027] See Figure 1 As shown in the figure, in order to further improve the protection effect on the internal structure of the cable, a sheath is also provided in this embodiment. The sheath covers the outer surface of the waterproof component 300. Among them, the sheath base material is a cross-linked polyolefin material, preferably polyurethane material in this embodiment.
