1, 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 weaknesses, only a small number of oil-immersed transformers, oil-filled motor windings.
2, polyurethane enameled wire; thermal grade 130, 155, 180, 200. Z is characterized by straight welding, high-frequency performance resistance, 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-resistant performance 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-sized and micro-fine line for more.
3, polyester and modified polyester enameled wire, ordinary polyester enameled wire thermal level of 130, after modification of the enameled wire thermal level of 155. The product has high mechanical strength, and has good elasticity, adhesion, electrical properties and solvent resistance, the weak point is the poor performance of heat shock, moisture resistance is low. It is a variety of China's current production Z large, accounting for about two-thirds, widely used in a variety of motors, electrical appliances, instruments, telecommunications equipment and home appliances.
4, 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, cold resistance, radiation resistance and other characteristics, high mechanical strength, stable electrical properties, chemical resistance and good freezing agent resistance, overload capacity. Widely used in refrigerator compressor, air conditioner compressor, power tools, explosion-proof motor and high temperature, high cold, radiation resistance, overload and other conditions of the use of motors, electrical appliances.
5, polyester imide / polyamide composite enameled wire, thermal grade 180 The product has good thermal shock resistance, high softening breakdown temperature, excellent mechanical strength, solvent resistance and freezing agent resistance are good, 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.
