[0013] The accompanying drawings in this utility model are all schematic diagrams and their sizes do not represent actual dimensions.

[0014] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0016] like Figure 1 As shown, a fire-resistant cable for preventing ants and rodents includes: a support bar 1, with several conductors 2 wound around the outside of the support bar 1, a shielding layer 3 covering the outside of the conductors 2, an inner sheath 4 covering the outside of the shielding layer 3, a composite fire-resistant layer 5 covering the outside of the inner sheath 4, a steel wire 6 wound around the outside of the composite fire-resistant layer 5, a rubber layer 7 covering the outside of the steel wire 6, a protective steel wire 8 threaded inside the rubber layer 7, several metal-plastic composite strips 9 evenly arranged axially on the outside of the rubber layer 7, an insect repellent 10 filled between two adjacent metal-plastic composite strips 9, and an ant- and rodent-proof outer sheath 11 covering the outside of the metal-plastic composite strips 9. Due to the properties of refractory materials, cables have poor flexibility in bending and stretching, which may limit their use in certain applications. The steel wire 6 is spirally wound on the cable to provide a spring-like structure. When the cable is subjected to traction, it can be buffered by the steel wire winding layer 10, which improves the tensile strength of the cable. The protective steel wire 8 is evenly distributed on the outside of the cable through the rubber layer 7, which improves the bending resistance of the cable.

[0017] The conductor 2 includes a core 12, and the core 12 is covered with an insulation layer 13.

[0018] The anti-termite and anti-rodent outer sheath 11 is made of polyvinyl lactone and has a thickness of 0.5 mm or more. When the thickness of the polyvinyl lactone protective layer reaches 0.2 mm, it can prevent termites from damaging the wire and cable products. When its thickness reaches 0.5 mm or more, it can effectively prevent rats from biting the wire and cable.

[0019] The composite fire-resistant layer 5 comprises a glass fiber belt and a layer of ceramicized silicone rubber wrapped outside the glass fiber belt.

[0020] The inner sheath 4 is made of cross-linked polyethylene.

[0021] The support strip 1 is made of polypropylene.

[0022] The principle of the utility model is: when the photovoltaic cable is eroded by insects and mice, the internal cable is protected through the anti-insect and mouse outer sheath 11 structure of the outer layer of the cable, if the anti-insect and mouse outer sheath 11 is bitten by insects and mice, the insects and ants are driven away through the insect repellent 10 between the metal plastic composite strips 9. The composite fire-resistant layer 5 composed of the glass fiber belt and the ceramicized silicone rubber layer improves the fire-resistant and flame-retardant performance of the cable and prevents the cable from catching fire.

[0023] The utility model has been described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above-mentioned mode, as long as various improvements are made by adopting the method concept and technical scheme of the utility model or directly applied to other occasions without improvement, which are all within the protection scope of the utility model.
