  1. enameled wire; thermal grade is 105 and 120, with good mechanical strength, adhesion, resistance to transformer oil and refrigerant, but the product has poor moisture resistance, low thermal softening breakdown temperature, and durable benzene-alcohol mixture Defects such as weak solvent performance, currently only a small amount is used in the windings of oil-immersed transformers and oil-filled motors.
  2. Polyester and modified polyester enameled wire, ordinary polyester enameled wire, the thermal class is 130, and the thermal class of the modified enameled wire is 155. This product has high mechanical strength, good elasticity, scratch resistance, adhesion, electrical properties and solvent resistance. It is currently the largest product in my country, accounting for about two-thirds: widely used in various motors, Electrical appliances, meters, telecommunications equipment and home appliances; the weaknesses of this product are poor thermal shock resistance and low moisture resistance.
  3. Polyurethane enameled wire; thermal grade is 130.155.180. The biggest feature is that it has direct solderability, good high frequency resistance, easy coloring, and good moisture resistance. It is widely used in electronic appliances, precision instruments, telecommunications, and meters. The weakness of this product is that its mechanical strength is slightly poor, and its heat resistance is not high. , And the flexibility and adhesion of the production of large-size wires are poor, so the product specifications are mostly small and fine lines.
  4. Polyesterimide enameled wire, thermal class 180. This product has good thermal shock resistance, high resistance to softening and breakdown temperature, excellent mechanical strength, and good resistance to solvents and refrigerants. The weakness is that it is easy to hydrolyze under closed conditions. It is widely used in windings of motors, electrical appliances, meters, power tools and electric dry-type compressors that require high heat resistance.
  5. Polyesterimide/polyamideimide composite layer aluminum magnet wire is a heat-resistant enameled wire widely used at home and abroad. Its thermal class is 200. This product has high heat resistance, and is also resistant to refrigerants Severe cold, radiation resistance, high mechanical strength, stable electrical performance, good chemical resistance and refrigerant resistance, and strong overload capacity. It is widely used in refrigerator compressors, air-conditioning compressors, electric tools, explosion-proof motors and motors and electrical appliances used under high temperature, high cold, radiation resistance, and overload conditions.
