[0017] Example 1

[0018] Figure 1 This is a schematic diagram of the cross-sectional structure of the anti-signal interference wire and cable provided in this embodiment of the utility model. Please refer to... Figure 1 The anti-signal interference wire and cable provided in this embodiment includes a Teflon sheath 100, a silver-plated shielding layer 200, a PTFE tape 300, a Teflon insulation layer 400, a glass fiber filling portion 500, and a silver-plated conductor 600. Four silver-plated conductors 600 are wrapped within the PTFE tape 300, and the Teflon insulation layer 400 is wrapped around the surface of each silver-plated conductor 600. The silver-plated shielding layer 200 is wrapped around the outside of the PTFE tape 300, and the Teflon sheath 100 is wrapped around the outside of the silver-plated shielding layer 200. The gaps between the four Teflon insulation layers 400 and the gaps between the PTFE tape 300 and the Teflon insulation layer 400 are filled with the glass fiber filling portion 500.

[0019] It should be noted that the Teflon material in Teflon-coated 100 has excellent corrosion resistance, resisting oil, strong acids, strong alkalis, and strong oxidants; it also has excellent electrical insulation properties, high voltage resistance, low high-frequency loss, non-hygroscopicity, and high insulation resistance; and excellent flame retardancy, aging resistance, and long service life.

[0020] Silver in the silver-plated shielding layer 200 has the best conductivity, which can significantly reduce cable resistance and reduce signal loss caused by the skin effect. In high-frequency scenarios, the silver-plated layer can improve the signal-to-noise ratio, enhance the electromagnetic shielding effect, and ensure signal stability.

[0021] PTFE tape 300 has excellent high temperature resistance, excellent electrical insulation, strong moisture resistance, does not absorb water, is suitable for humid environments, and has strong corrosion resistance, resisting the erosion of chemicals such as acids, alkalis, and organic solvents.

[0022] Teflon insulation layer 400 features high temperature resistance, remaining stable within a temperature range of -100℃ to 250℃, making it particularly suitable for high-temperature environments; corrosion resistance, resisting strong acids, strong alkalis, organic solvents, and oxidants, making it suitable for chemical equipment and corrosive environments; flame retardancy, not easily ignited and self-extinguishing upon removal of the flame, offering higher safety than PVC insulated wires, suitable for fire-fighting equipment and other scenarios with high fire protection requirements; resistance to friction and aging, with a smooth and wear-resistant surface, long service life, suitable for applications involving frequent bending or sliding contact; high insulation resistance and low high-frequency loss.

[0023] The 500-layer glass fiber filling exhibits excellent electrical insulation properties, with a low dielectric constant and low dielectric loss, effectively isolating current and ensuring the electrical safety of wires and cables. It also boasts high temperature resistance and good thermal stability, maintaining high mechanical strength even at 300℃. Furthermore, it exhibits strong corrosion resistance, tolerating strong acids, strong alkalis, aqua regia, and organic solvents. It possesses high mechanical strength, with high tensile strength (6.3-6.9 g / d under standard conditions). While its abrasion resistance is relatively poor, this can be improved through process optimization. Finally, its non-adhesive properties prevent any substance from adhering to its surface, reducing impurities, keeping the cable interior clean, and minimizing signal transmission interference.

[0024] Silver-plated conductor 600 is a silver-plated copper wire conductor with excellent conductivity. The resistivity of silver is 1.6 × 10⁻⁶. 8 Ω·m) is lower than that of copper (1.7×10 8 With a resistance of Ω·m, it exhibits superior conductivity, making it particularly suitable for low-current applications such as control circuits. It can significantly reduce resistance and improve conductivity efficiency. It is also corrosion-resistant and oxidation-resistant, with the silver plating layer effectively resisting corrosion from oil, strong acids, strong alkalis, and strong oxidants. It is suitable for electrical connections in complex environments, extending its service life. Furthermore, it offers reliable electrical insulation performance. The silver-plated conductor is characterized by high voltage resistance, low high-frequency loss, and non-hygroscopic properties. Its high insulation resistance makes it suitable for applications requiring high stability.
