[0023] Twisted-pair cables are commonly used to connect various electronic devices and electrical systems, playing a vital role in daily life. However, termites, rats, and rabbits, among other creatures, have a habit of gnawing during their foraging process. During daily use, twisted-pair cables are susceptible to gnawing damage. Gnawed photovoltaic cables can lead to short circuits and disconnections, potentially causing power outages, telecommunications disruptions, and other incidents, resulting in losses to social activities and the national economy.

[0024] To this end, the present invention proposes a rat-proof and ant-proof twisted pair wire 1000, specifically referring to the accompanying drawings of the specification. Figure 1 shown.

[0025] Reference Figure 1 As shown, a twisted pair cable 1000 for preventing rodents and ants according to one embodiment of the present invention includes two wires 100, which are twisted together to form a twisted pair. It should be noted that this arrangement can reduce the effects of electromagnetic radiation and external electromagnetic interference, thereby improving signal transmission quality and stability. It can also reduce mutual interference between the multiple twisted pairs.

[0026] Reference Figure 1 As shown, it should be noted that the wire 100 includes a conductor 110, an inner insulation layer 120, a rodent-proof and termite-proof layer 130, and an outer insulation layer 140. The inner insulation layer 120 is disposed on the outer periphery of the conductor 110, the rodent-proof and termite-proof layer 130 is disposed on the outer periphery of the inner insulation layer 120, and the outer insulation layer 140 is disposed on the outer periphery of the rodent-proof and termite-proof layer 130. In other words, the inner insulation layer 120, the rodent-proof and termite-proof layer 130, and the outer insulation layer 140 are arranged in sequence on the outer periphery of the conductor 110. It should be noted that both the inner insulation layer 120 and the outer insulation layer 140 serve as insulation. It should also be noted that the rodent-proof and termite-proof layer 130 has excellent corrosion resistance, providing protection against infestation by termites, mice, rabbits, and other organisms.

[0027] Continue to refer to Figure 1 As shown, it can be understood that since the inner insulating layer 120, the anti-rat and anti-termite layer 130 and the outer insulating layer 140 are sequentially arranged outside the conductor 110, the anti-rat and anti-termite twisted pair cable 1000 not only has good insulation properties, but can also effectively resist the erosion of organisms such as termites, mice or hares through the anti-rat and anti-termite layer 130, thereby reducing the occurrence of accidents such as power outages and telecommunication interruptions caused by erosion.

[0028] In one embodiment of the present invention, the rat-proof and ant-proof twisted pair cable 1000 has an anti-rat and ant-proof layer 130 made of nylon. It should be noted that nylon has many excellent properties, including high mechanical strength, fatigue resistance, heat resistance, corrosion resistance, and self-extinguishing properties, and can effectively protect against erosion by termites, rats, rabbits, and other organisms.

[0029] In one embodiment, the rodent- and termite-proof layer 130 is formed by extrusion of nylon resin. It should be noted that nylon resin is a type of plastic made from polyamide resins that exhibits excellent mechanical and physical properties, such as high-temperature performance, electrical properties, and flame retardancy. It also offers a good balance between high mechanical strength, rigidity, and toughness. Clearly, the rodent- and termite-proof layer 130 formed by extrusion of nylon resin can better protect against predators such as termites, rats, and hares.

[0030] In one embodiment of the present invention, the rodent-proof and ant-proof twisted-pair cable 1000 has an inner insulation layer 120 extruded from a 125°C halogen-free, low-smoke, irradiated cross-linked polyolefin material. This 125°C halogen-free, low-smoke, irradiated cross-linked polyolefin material is an environmentally friendly cable insulation material with numerous excellent properties. This material primarily uses polyolefin as a base material, blended and modified with halogen-free flame retardants and cross-linking aids.

[0031] It should also be noted that the 125°C halogen-free, low-smoke, irradiated cross-linked polyolefin material exhibits excellent insulation and flame retardancy, maintaining stable physical and chemical properties even at high temperatures. Furthermore, it is environmentally friendly. Since it contains no halogens, it does not produce toxic or corrosive gases during combustion. Therefore, if the rodent- and ant-proof twisted pair cable 1000 were to catch fire, the inner insulation layer 120 would not emit toxic or harmful gases, thus meeting environmental protection requirements.

[0032] In one embodiment of the present invention, the rat-proof and ant-proof twisted pair cable 1000 utilizes a double-layer co-extrusion method to form the rat-proof and ant-proof layer 130 and the inner insulating layer 120. This arrangement provides for a more stable overall structure and enhanced resistance to food infestation. In one embodiment, the rat-proof and ant-proof layer 130 utilizes a nylon resin material, while the inner insulating layer 120 utilizes a 125°C halogen-free, low-smoke, irradiated, cross-linked polyolefin material. This double-layer co-extrusion method further stabilizes the overall structure of the rat-proof and ant-proof twisted pair cable 1000 and improves its resistance to food infestation.

[0033] In one embodiment of the present invention, the outer insulation layer 140 of the rat-proof and ant-proof twisted-pair cable 1000 is extruded from a 125°C halogen-free, low-smoke, irradiated, cross-linked polyolefin material. It should be noted that 125°C halogen-free, low-smoke, irradiated, cross-linked polyolefin material is an environmentally friendly cable insulation material with multiple excellent properties. This material is primarily composed of a polyolefin base material, which is blended and modified by the addition of halogen-free flame retardants and cross-linking aids.

[0034] It should also be noted that the 125°C halogen-free, low-smoke, irradiated cross-linked polyolefin material exhibits excellent insulation and flame retardancy, maintaining stable physical and chemical properties even at high temperatures. Furthermore, it is environmentally friendly. Since it contains no halogens, it does not produce toxic or corrosive gases during combustion. Therefore, if the rodent- and ant-proof twisted pair cable 1000 were to catch fire, the outer insulation layer 140 would not emit toxic or harmful gases, thus meeting environmental protection requirements.

[0035] Reference Figure 1 As shown, in one embodiment of the present invention, a twisted-pair cable 1000 for rodent and ant protection, conductor 110 is constructed from multiple strands of copper monofilaments. As will be appreciated, twisted copper conductors offer excellent conductivity and ductility, effectively enhancing the flexibility and tensile strength of the twisted-pair cable 1000. In one embodiment, the copper monofilaments are required to have a higher tensile strength than Category 5 conductors, thereby effectively increasing the cable's tensile strength.

[0036] Reference Figure 1 As shown, the rat-proof and ant-proof twisted pair cable 1000 of one embodiment of the present invention further includes a fire-resistant layer 150. The fire-resistant layer 150 is arranged between the outer peripheral side of the conductor 110 and the inner peripheral side of the inner insulating layer 120. That is to say, on the outer peripheral side of the conductor 110, the fire-resistant layer 150, the inner insulating layer 120, the rat-proof and ant-proof layer 130 and the outer insulating layer 140 are arranged in sequence. The inner insulating layer 120 and the outer insulating layer 140 both play an insulating role, and the rat-proof and ant-proof layer 130 plays a role in resisting the erosion of organisms such as termites, mice or hares. The fire-resistant layer 150 has good fire resistance and is closest to the conductor 110. Therefore, when the conductor 110 is seriously heated, the fire-resistant layer 150 can withstand the high temperature and separate the seriously heated conductor 110 from other components.

[0037] In one embodiment, the fire-resistant layer 150 is formed by wrapping phlogopite tape. It should be noted that phlogopite tape is a high-performance fire-resistant insulation material with excellent fire resistance, acid and alkali resistance, corona resistance, and radiation resistance, as well as good flexibility and tensile strength, making it an ideal material for the fire-resistant layer 150. It is understood that the provision of the fire-resistant layer 150 formed by wrapping phlogopite tape can effectively reduce the occurrence of fire accidents during the use of the rodent-proof and ant-proof twisted pair cable 1000.

[0038] The above describes the embodiments of the present invention in detail with reference to the accompanying drawings. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
