Enameled wire manufacturers to tell you the characteristics and uses of commonly used enameled wire

Acetal enameled wire; thermal grade 105 and 120 two, with good mechanical strength, adhesion, resistance to transformer oil and cold media performance, but the product moisture resistance, low thermal softening breakdown temperature, durable benzene - alcohol mixed solvent performance is weak and other defects, currently only a small number of oil-immersed transformers, oil-filled motor windings.

2. Polyester and modified polyester enameled wire, ordinary polyester enameled wire, the thermal level of 130, after modification of the enameled wire thermal level of 155. The product has high mechanical strength, and has good elasticity, scratch resistance, adhesion, electrical properties and solvent resistance, it is China's current production Z a large number of varieties, accounting for about two-thirds: widely used in a variety of motors, electrical appliances, meters, telecommunications equipment and home appliances; the product's weakness is the poor performance of heat shock, low moisture resistance.

3. Polyurethane enameled wire; thermal grade 130.155.180.Z is characterized by straight welding, high-frequency performance, easy coloring, good moisture resistance, should be widely used in electronic appliances and precision instruments, telecommunications, instruments, the weakness of the product is slightly poor mechanical strength, heat resistance is not high, and the production of large-size line flexibility and adhesion is poor, so the production of the product specifications to small and medium and micro-fine line. Line for more.


4. polyester imide enameled wire, thermal grade 180 the product heat shock resistance, high softening breakdown temperature, excellent mechanical strength, solvent resistance and freezing agent resistance are better, the weak point is easy to hydrolysis under closed conditions, widely used in heat-resistant requirements of high motor, electrical appliances, instrumentation, power tools, electric dry voltage and other windings.

5. polyester imide / polyamide imide composite layer enameled wire it is more widely used at home and abroad heat-resistant enameled wire, the thermal level of 200, the product has high heat resistance, but also has a freezing agent resistance, cold resistance, radiation resistance and other characteristics, high mechanical strength, stable electrical properties, chemical resistance and freezing agent resistance performance, overload capacity. It is widely used in refrigerator compressor, air conditioner compressor, power tools, explosion-proof motors and motors and electrical appliances used under high temperature, high cold, radiation resistance and overload conditions.
