Fully Insulated FIW Grade three Zero-defect Enamelled Round Copper Wire Replace the Traditional TIW
Ultra-fine conductor: FIW enamelled wire is made of extremely fine pure copper conductor, which not only ensures excellent conductivity, but also provides excellent clarity of signal transmission, suitable for high-precision electronic devices.
Thin Coating Layer: The wire has a very thin insulating coating, which helps to reduce the overall wire diameter, making the wire softer while maintaining the necessary insulating properties for high-density wiring applications.
High Heat Resistance: FIW enamelled wire is designed to withstand high temperature environments, making it suitable for use in power amplifiers, high frequency transformers, and precision sensors.
Excellent Physical Strength: Despite the extremely fine conductors, enamelled wires have good physical strength and toughness, resisting breakage and abrasion to ensure long-term stable operation.
Low Loss: In high frequency applications, FIW enamelled wires exhibit low loss characteristics that have little or no effect on signal transmission, ensuring high quality communications.
Environmentally friendly materials: RoHS compliant and manufactured with environmentally friendly materials, they are both safe and have a low environmental impact.
Versatile applications: From miniature sensors to precision medical devices, FIW enamelled wires are used in a wide range of precision electronic devices due to their unique characteristics.
FIW enamelled wire represents an advancement in miniaturisation in wire and cable technology, with its ultra-fine conductors and thin insulation providing unparalleled benefits for precision circuits. Whether challenged by space constraints or high performance requirements, FIW enamelled wire offers reliable solutions for the most demanding applications.
