  Introduction of enameled wire classification:
  According to the classification of insulation grade, there are mainly the following types of commonly used enameled wires:
  1. Acetal enameled wire; The thermal level is 105 and 120, with good mechanical strength, adhesion, resistance to transformer oil and refrigerant performance, but the product moisture resistance performance is poor, thermal softening breakdown temperature is low, durable benzene-alcohol mixed solvent performance is weak and other defects, currently only a small number of oil immersed transformer, oil filled motor winding.
  2. Polyester and modified polyester enameled wire, ordinary polyester enameled wire, heat level of 130, modified enameled wire heat level of 155. The product has high mechanical strength, good elasticity, scratch resistance, adhesion, electrical properties and solvent resistance. It is the largest product in China, accounting for about two-thirds: widely used in a variety of motors, electrical appliances, instruments, telecommunications equipment and home appliances products; The weak spot of the product has poor thermal shock resistance and low moisture resistance.
  3. Polyurethane enameled wire; The heat level is 130, 155 and 180. The biggest characteristic is straight welding resistance, resistance to high frequency performance is good, easy coloring, moisture resistant performance is good, the product weakness is a bit poor mechanical strength, heat resistance is not high, and the production of large size line flexibility and adhesion is bad, should be widely in electronic appliances, fan motors and precision instruments, telecommunications, the finest of all kinds of heat resistance is not very high, but effective demand production products.
  4. Polyester imide enamulated wire, thermal class 180 this product has good heat shock resistance performance, high resistance to softening breakdown temperature, good mechanical strength, solvent resistance and refrigerant resistance performance are good, easy hydrolysis under the weak point closed condition, widely used in heat resistance requirements of high motor, electrical appliances, instruments, electric tools, electric power dry type presser and other winding.
  5. Polyester imide/polyamide imide enamelled wire si composite layer is more widely used at home and abroad to heat enameled wire, thermal level 200220, high heat resistance, the product has a refrigerant resistance, cold resistance, radiation resistance and other properties, high mechanical strength, electrical performance stability, good chemical resistance and freeze resistance performance, overload ability. It is widely used in refrigerator compressor, air conditioning compressor, electric tools, explosion-proof motor and motor and electrical appliances under high temperature, cold, radiation resistance, overload and other conditions.
  According to the conductor material classification, can be divided into the following:
  Copper enameled wire, AL enameled wire, CCA
  According to the material shape: round enameled wire, flat enameled wire
  According to the insulation paint thickness classification: circle line: ultra-thin film -0, thin film -1, thick film -2, thickened film -3; Flat wire: ordinary film -1 thickened film -2
  An electrical material consisting of an inner conductor and an extremely thin layer of high-voltage insulation. Enameled wire has good insulation effect and waterproof ability, and is widely used in electrical appliances, such as motors, generators, water pumps, electromagnets, welders, household appliances, wireless communication, loudspeakers, telegrams, transformers and so on.
