Enameled Wire is one of the most important types of electromagnetic wire, consisting of conductor and the insulating layer. Bare wire is annealed and softened, then painted and baked several times. The quality characteristics of various enameled wires are different, but they all have four major functions: mechanical function, chemical function, electrical function and thermal function. Online measurement of enameled wire can effectively control the size and quality of goods. The enameled wire in production runs at a high speed, and there is no way to measure accurate data with any touching measurement, and when the enameled wire standard is relatively small, disconnection is simply formed.
Acetal enameled wire has good mechanical strength, adhesion, transformer oil resistance and refrigerant resistance. However, this product has poor moisture resistance, low thermal softening breakdown temperature and weak function with benzene-alcohol mixed solvent. Currently, it is only used for windings of oil-immersed transformers and oil-filled motors. Polyamide composite enameled wire has good thermal shock resistance, high softening and breakdown temperature resistance, excellent mechanical strength, good solvent resistance and cryogen resistance. Its disadvantage is that it is easy to hydrolyze under closed conditions, and is widely used in windings such as motors, electrical appliances, external surfaces, electric east-west power dry pressure devices with high heat resistance requirements.
