Overview
Glass Fiber Wrapped Enameled Flat Copper Wire 180 is a high-performance wire material designed for applications that require high temperature resistance, high voltage and high current. It combines the excellent insulation of glass fiber and the stability of enameled wire, as well as the good heat dissipation of flat copper wire, so that the wire can maintain excellent electrical performance under extreme conditions. In particular, its 180-level heat resistance ensures that the wire can also work stably in high temperature environments.
Material Properties
High temperature resistance: The 180-level heat resistance enables it to maintain stable electrical performance in high temperature environments without softening or melting.
Excellent insulation: The glass fiber wrapping layer provides excellent insulation performance for the wire, effectively preventing current leakage and electrical failure.
High electrical performance: The copper core conductor ensures the low resistance and high conductivity of the wire, making current transmission more efficient.
Mechanical properties: The glass fiber wrapping layer enhances the mechanical strength of the product and improves wear resistance and tensile resistance.
Good heat dissipation: The flat copper wire design increases the heat dissipation area of the wire and effectively reduces the temperature of the wire during operation.

Production process:
Copper flat wire processing: high-purity copper materials are made into flat wires through stretching, rolling and other processing procedures.
Insulation paint coating: special molds or equipment are used to evenly coat the high-temperature resistant insulation paint on the surface of the copper flat wire.
Glass wire wrapping: after the insulation paint is cured, glass wire is used for wrapping to form a glass wire wrapping layer.
Finished product inspection: the finished product is tested for electrical properties, heat resistance, mechanical strength and other aspects to ensure that it meets quality requirements.
VII. Application areas
New energy vehicles: used in high temperature and high pressure environments such as battery management systems and drive systems.
Motor manufacturing: used to manufacture various types of motors, such as generators, motors, etc., to meet their high requirements for electrical transmission.
Transformer manufacturing: used as winding wires in transformers to ensure the stability and safety of current transmission.
Electrical equipment: used as electrical connecting wires and winding wires in various electrical equipment to improve the performance and reliability of the equipment.
Summary
Glass fiber wrapped enameled rectangular copper wire 180 grade has broad application prospects in the electrical field.
