Embodiment 1

[0025] Please refer to Figures 1-4, a technical solution provided by the present utility model: an anti-corrosion low-voltage cable, including a cable wire 9, the cable wire 9 includes a corrosion-resistant protective sleeve 1 arranged on the outermost layer, an armor layer 2 is arranged on the inner wall of the corrosion-resistant protective sleeve 1, a flame-retardant layer 3 is arranged on the inner wall of the armor layer 2, and a plurality of low-voltage conductive cores 7 are arranged on the inner wall of the flame-retardant layer 3.

[0026] Among them, the corrosion-resistant protective sleeve 1 is made of any one of polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), rubber, etc.

[0027] Polyvinyl chloride (PVC) is a commonly used cable skin protection sleeve material, which has good corrosion resistance, wear resistance and anti-aging properties. The PVC protection sleeve can be used in various environments such as indoor and outdoor, and is suitable for most low-voltage cables.

[0028] Cross-linked polyethylene (XLPE) is a specially treated polyethylene material, which has higher heat resistance and corrosion resistance. The XLPE protection sleeve is widely used in the fields of power cables, control cables, etc.

[0030] During use, due to reasons such as high temperature, combustion may occur. To reduce the occurrence of combustion, a flame-retardant filler 4 is filled between adjacent low-voltage conductive cores 7 on the inner wall of the flame-retardant layer 3. The flame-retardant filler 4 is a silicate material, and the armor layer 2 is used to control the tightness of the flame-retardant filler 4 to avoid rupture.

The outer wall of the core sheath 6 is wrapped with an insulating layer 5, and the insulating layer 5 is polyethylene (PE).

[0032] The flame-retardant layer 3 is filled with a flame-retardant filler 4. The flame-retardant filler 4 is a fine granular powder. The flame-retardant filler 4 is a silicate material, specifically calcium silicate. The flame-retardant filler 4 can prevent combustion, resist corrosion and provide a certain strength for the cable. It should be noted that in other specific embodiments, the above flame-retardant filler 4 can also be magnesium silicate or a mixture of magnesium silicate and calcium silicate.

[0033] The insulating layer 5 on the outer wall of the low-voltage conductive core 7 is filled and fixed in the inner circle of the flame-retardant layer 3 through the flame-retardant filler 4. Embodiment 2
