Basic composition and materials
Conductor: Copper or copper alloy is usually used as the conductor material, because copper has good electrical conductivity and can effectively transmit current. For example, the common ones are bare copper wires, tinned copper wires, etc., and the appropriate copper types and wire diameter specifications are selected according to the specific use needs.
Insulation: Its core feature is that Teflon (polytetrafluoroethylene, PTFE) is overplasticized and wrapped as an insulating outer layer on the conductor. Teflon is a polymer material with excellent properties, which imparts unique properties below stranded wires.
Performance characteristics:
High temperature resistance: Teflon material itself has extremely high high temperature resistance, so that Teflon plastic stranded wire can work normally in a wide range of temperatures. In general, it maintains stable physical and electrical properties in temperatures ranging from -200°C to +260°C, which is critical in many industrial applications in high-temperature environments, such as wiring electrical equipment near high-temperature furnaces.
Corrosion resistance: Extremely resistant to most chemicals, including strong acids, bases, organic solvents, etc. Whether in an environment where large amounts of corrosive chemicals are present in a chemical production plant, or outdoors where it may be subjected to acid rain or other erosion, Teflon stranded wire can effectively resist corrosion and ensure the reliability and durability of electrical connections.
Low coefficient of friction: Teflon has a very smooth surface and has a very low coefficient of friction. This makes the stranded wire more smoothly when wiring through narrow pipes, trunking, etc., and is not easy to damage the insulation layer or jam due to friction, which is convenient for installation and subsequent maintenance.
Electrical insulation performance: As an insulating material, Teflon provides excellent electrical insulation properties, which can effectively prevent current leakage and ensure the safe operation of the electrical system. Even in harsh electrical environments such as high humidity and high voltage, it can maintain good insulation.
Mechanical properties: Although the Teflon material is relatively soft, the Teflon plastic stranded wire still has a certain mechanical strength as a whole, and can withstand a certain degree of external force such as stretching and bending without being easily damaged. However, in practical applications, it is also necessary to reasonably control the degree of external force applied to it according to the specific use scenario.
Fields of application
Aerospace field: In aircraft, satellites and other aerospace equipment, due to its extremely high requirements for material properties, not only to withstand extreme temperature changes, but also to have anti-corrosion and other characteristics, Teflon plastic stranded wire is widely used in the wiring of various electrical systems, such as flight control systems, communication systems, etc.
Chemical industry: The chemical production environment is often filled with various corrosive chemicals, and ordinary wires are difficult to meet the requirements. Teflon stranded wire can be used for electrical connections in and around chemical equipment due to its excellent corrosion resistance, ensuring the normal operation of electrical circuits in harsh chemical environments.
Medical equipment: In some high-precision medical equipment, such as magnetic resonance imaging (MRI) equipment, medical electronic instruments, etc., wires need to be able to work stably in a relatively closed environment where there may be certain temperature changes, and to meet the strict requirements of medical equipment for material safety. Teflon stranded wire meets these needs and is therefore also used in the wiring of medical devices.
Electronic and electrical industry: In the internal wiring of various electronic and electrical products, Teflon plastic stranded wire can provide good electrical insulation and easy installation, such as computer motherboards, high-end TVs and other products may be used
