The cable includes a power cable, a control cable, a shield cable, a high-temperature cable, a computer cable, a signal cable, a coaxial cable, a fire-resistant cable, an aluminum alloy cable, and the like. They are composed of single or multi-strand wires and insulating layers, and are used for connecting circuits, electric appliances and the like. All the electric wires and cables are made by processing conductors, and adding insulation, shielding, cabling, sheath and the like layer by layer on the periphery of the conductors to form electric wire and cable products. The more complex the product structure, the more levels are superimposed. However, the conventional flame-retardant cable only adds a flame retardant on the surface of the rubber protective sleeve in the process of manufacturing the cable, which does not prevent combustion well, and the conventional cable cannot prevent rats from biting.

the insulating protective sleeve covers the cable conductor, the cable conductor covered with the insulating protective sleeve is distributed at the bifurcation of the Y-shaped protective piece, and the filling material is filled between the insulating protective sleeve and the Y-shaped protective piece to form the cable inner core with a circular section.
Further, the Y-shaped protection piece is made of nylon.
Further, the insulating protective sleeve is made of ethylene-tetrafluoroethylene copolymer.
Further, the filling material is cotton threads.
Furthermore, the steel wire armor layer is formed by weaving stainless steel wires with the diameter of 0.05-0.1 mm.
Further, the insulating layer comprises the following components in percentage by mass:
48-52% of low-smoke halogen-free flame-retardant polyolefin cable material, 30-34% of plasticizer, 10-13% of calcium carbonate and 1-5% of environment-friendly ratproof agent.
Furthermore, the diameter of the stainless steel wire used for weaving in the stainless steel woven net layer is 0.15-0.2 mm.
Has the advantages that: the rat-proof fire-resistant security cable provided by the invention can effectively prevent rats and ants from gnawing, has good fire-resistant and flame-retardant performances, furthest ensures the operation safety of security equipment, and provides the greatest guarantee for the life and property safety of people.

FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1, the rat-proof fire-resistant security cable comprises a cable inner core, a steel wire armor layer 5, an asphalt anti-corrosion protective layer 6, an insulating layer 7 and a stainless steel woven mesh layer 8 which are sequentially arranged from inside to outside.
The cable inner core comprises a cable conductor 1, an insulating protective sleeve 2, a Y-shaped protective piece 3 and a filling material 4, wherein the insulating protective sleeve 2 is coated outside the cable conductor 1, the cable conductor 1 coated with the insulating protective sleeve 2 is distributed at the branch position of the Y-shaped protective piece 3, and the filling material 4 is filled between the insulating protective sleeve 2 and the Y-shaped protective piece 3 to form the cable inner core with a circular cross section.
The insulating protective sleeve 2 is made of an ETFE (ethylene tetrafluoroethylene copolymer) material, so that the corrosion of flame to the cable conductor 1 can be prevented, and the cable combustion caused by electric sparks generated by the cable conductor 1 during short circuit can also be prevented.
The Y-shaped protection piece 3 is made of nylon materials, the protection piece is designed into a Y shape and has a stable triangular structure, and the cable conductors are distributed at the bifurcation, so that on one hand, the deformation of the cable can be reduced when the cable is extruded by external force, the short circuit among the cable conductors 1 is avoided, and the safety is improved; on the other hand, the nylon material has high temperature resistance and can resist the temperature of 125-250 ℃. The safety and overall stability of the cable can be greatly improved by the mounting of the Y-shaped protection 3.
The filling material 4 is a cotton thin-wire material, is used for improving the extrusion resistance and the impact resistance, can improve the overall flexibility and elasticity of the cable, and simultaneously shares the tensile force acting on the cable, thereby playing the role of axial protection.
The steel wire armor layer 5 is woven by stainless steel wires with the diameter of 0.05-0.1 mm, so that the shielding effect is achieved, the interference of current signals to external signals is reduced, and a barrier for preventing animals such as rats and ants from biting cables can be added.
