[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a high temperature resistant wire, including installation layer 1:

[0022] Three groups of wires 2 are provided in installation layer 1, fixed layer 3 is provided on the outside of installation layer 1, high temperature resistant layer 6 is provided on the outside of fixed layer 3, and protective layer 7 is provided on the outside of high temperature resistant layer 6.

[0023] Fixed layer 3 is uniformly provided with multiple fixed convex lines 4, and the outside of installation layer 1 and the inside of high temperature resistant layer 6 are both provided with fixed grooves matched therewith, and multiple fixed convex lines 4 can effectively prevent internal wires 2 from being displaced under external force, so as to maintain the overall structural stability of the wire, and the provision of fixed convex lines 4 helps to reduce the abrasion of internal wires 2 caused by vibration, prolongs the service life of the wire, and through the cooperation of fixed convex lines 4 and fixed grooves, the overall tensile strength of the wire is improved, making it more suitable for use in complex environments.

[0024] The plurality of fixed convex lines 4 are internally provided with reinforcing bars 5, and the reinforcing bars 5 are woven from low-carbon galvanized steel wires. The reinforcing bars 5 are woven from low-carbon galvanized steel wires, which have high strength and good elasticity, can significantly improve the tensile strength of the wire, prevent breakage due to pulling during use, and the woven reinforcing bars 5 have a compact structure that can disperse pressure under external pressure and reduce the local stress on the wire, thereby improving the overall pressure resistance of the wire. The presence of the reinforcing bars 5 allows the wire to maintain its structural integrity and stability when subjected to external forces, preventing deformation that affects performance. The use of reinforcing bars 5 can effectively extend the service life of the wire, especially in harsh environments such as high temperature and high pressure. Low-carbon galvanized steel wire has good corrosion resistance, protecting the wire from damage even in humid or chemically corrosive environments. Due to the durability of the reinforcing bars 5, maintenance and replacement frequency can be reduced, thereby reducing maintenance costs.

[0025] The fixed layer 3 is made of polytetrafluoroethylene, which has strong resistance to most chemicals, including acids, bases, and solvents. This helps protect the wire from chemical erosion. Polytetrafluoroethylene is an excellent electrical insulator that maintains good insulation performance even in high-temperature or humid environments, which is crucial for the safety of the wire. Due to its chemical stability, polytetrafluoroethylene wire is less likely to be damaged in harsh environments, reducing the need for maintenance and replacement. Polytetrafluoroethylene has a very low coefficient of friction, which greatly reduces wear and tear during use, improving the durability of the wire. Although polytetrafluoroethylene is soft and has some elasticity, it also has good mechanical strength and can withstand certain external forces without breaking. Due to its wear resistance and mechanical strength, polytetrafluoroethylene wire is suitable for various complex and demanding environments, such as industrial automation equipment and aerospace applications.

[0026] The high-temperature resistant layer 6 is made of polyimide, which has extremely high heat resistance and can maintain stable performance under long-term high-temperature conditions. It can even withstand higher temperatures for a short time, allowing the wire to maintain good electrical performance and structural integrity in high-temperature environments. The physical and chemical properties of polyimide remain stable under high temperatures, without affecting its structure and function due to temperature changes, ensuring the reliability and safety of the wire. Due to its high-temperature resistance, polyimide wire has a significantly longer service life in high-temperature environments, reducing replacement frequency and maintenance costs.

[0027] The protective layer 7 is made of synthetic mica tape material, which has excellent mechanical strength and can effectively resist physical damage and wear from the outside, which improves the service life and reliability of the wire in complex environments. Synthetic mica tape has excellent electrical insulation performance and can effectively prevent current leakage and short circuit accidents, which provides an important guarantee for the safe operation of the wire, especially in high-voltage environments. Synthetic mica tape has good resistance to a variety of chemicals and can remain stable in acid, alkali, solvent, and other corrosive environments, making the wire more widely used in special fields such as chemical industry and marine. Synthetic mica tape is flexible and easy to bend and install, suitable for various complex wiring needs. Its lightness and flexibility make it easier to lay and maintain the wire, reducing construction time and cost. Synthetic mica tape not only resists high temperatures but also provides an additional thermal protection layer to prevent direct effects of high-temperature environments on the internal conductor 2, further improving the stability and safety of the wire in high-temperature working conditions.
