1. Acetal enameled wire; Thermal grade 105 and 120, with good mechanical strength, adhesion, transformer oil and refrigerant resistance, but the product has poor moisture resistance, low thermal softening breakdown temperature, and weak resistance to benzene-alcohol mixed solvents. At present, only a small number of them are used in oil-immersed transformers and oil-filled motor windings.

2. Polyester and modified polyester enameled wires, ordinary polyester enameled wires, thermal class 130, modified enameled wires thermal class 155. The product has high mechanical strength, good elasticity, scratch resistance, adhesion, electrical properties and solvent resistance. It is my product.

At present, China's largest production of a variety, accounting for about two-thirds: widely used in a variety of motors, electrical appliances, instrumentation, telecommunications equipment and household appliances products; the product's weakness is poor heat shock resistance, low moisture resistance.

3. Polyurethane enameled wire; thermal grade 130.155.180. The greatest feature is direct solderability, good high frequency resistance, easy coloring, good moisture resistance. It should be widely used in electronic household appliances and precision instruments, telecommunications, instruments, the product's weakness is slightly poor mechanical strength, low heat resistance, and production of large specifications of the flexibility and adhesion of the wire is poor, so the specifications of the product production. Most of them are small and medium-sized wires.

4. Polyesterimide enameled wire, heat class 180, this product has good heat shock resistance, high softening breakdown temperature, good mechanical strength, good solvent resistance and refrigerant resistance. Its weakness is easy to hydrolyze under closed conditions. It is widely used in windings of motor, electrical appliances, meters, power tools, dry-type transformers and other windings with high heat resistance requirements.

5. Polyesterimide/polyamide imide composite coated enameled wire is widely used at home and abroad at present. Its heat level is 200. The product has high heat resistance, high freezing resistance, cold resistance, radiation resistance, high mechanical strength, stable electrical performance, good chemical and refrigerant resistance, and strong overload capacity. Widely used in refrigerator compressor, air conditioning compressor, electric tools, explosion-proof motor and high temperature, cold, radiation resistance, overload and other conditions under the use of motor, electrical appliances.
