1. Acetal enameled wire, with two thermal grades of 105 and 120, has good mechanical strength, adhesion, transformer oil resistance and refrigerant resistance, but the product has poor moisture resistance, low thermal softening breakdown temperature, and durable benzene-alcohol The mixed solvent performance is weak and other defects, only a small amount is used for the winding of oil-immersed transformers and oil-filled motors.
2. Polyurethane enameled wire; thermal grades are 130, 155, 180, 200. The biggest feature is that it has direct welding, good high frequency resistance, easy coloring, and good moisture resistance. It is widely used in electronic appliances and precision instruments, telecommunications, and instruments. 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 large-sized wires are poor, so the specifications of this product are mostly small and medium-sized wires.
3. For polyester and modified polyester enameled wires, the thermal grade of ordinary polyester enameled wire is 130, and the thermal grade of modified enameled wire is 155. The product has high mechanical strength, and has good elasticity, adhesion, electrical properties and solvent resistance. Its weaknesses are poor thermal shock resistance and low moisture resistance. It is currently the largest variety in my country, accounting for about two-thirds, and is widely used in various motors, electrical appliances, instruments, telecommunication equipment and home appliances.
4. Polyesterimide/polyamideimide composite layer enameled wire is a heat-resistant enameled wire widely used at home and abroad. Its thermal class is 200. Radiation and other characteristics, high mechanical strength, stable electrical performance, good chemical resistance and refrigerant resistance, and strong overload capacity. Widely used in refrigerator compressors, air-conditioning compressors, power tools, explosion-proof motors and motors and electrical appliances used in high temperature, high cold, radiation resistance, overload and other conditions.
5. Polyesterimide/polyamide composite enameled wire, thermal grade 180, the product has good thermal shock resistance, high softening breakdown temperature, excellent mechanical strength, good solvent resistance and refrigerant resistance, and its weakness is in closed conditions It is easy to be hydrolyzed, and is widely used in the windings of motors, electrical appliances, instruments, electric tools and power dry presses with high heat resistance requirements.
