The use of enamelled wire

2017/3/27      view:

    1, acetal enameled wire, thermal class 105 and 120 in two, good mechanical strength, good adhesion, resistance to transformer oil and refrigerant resistant performance, but the product moisture resistant performance is poor, low temperature heat soft breakdown, durable benzene alcohol mixed solvent performance is weak, only a small amount of oil for change transformer, oil filled motor winding.
    2, polyurethane enameled wire; the heat level was 130, 155, 180, 200 largest is characterized by direct welding, high frequency performance is good, easy coloring, moisture resistant properties, widely used in electronic appliances and precision instruments, telecommunications, instrumentation, the product is the weakness of mechanical strength is a bit poor, resistance the thermal performance is not high, and the production of large size line flexibility and adhesion is poor, so the product specifications and production in small and medium micro wire for.
    3, polyester and modified polyester enamelled wire, ordinary polyester enameled wire thermal grade is 130, after modification of enameled wire thermal level is level 155. The product has high mechanical strength, good elasticity, adhesion, electrical properties and solvent resistance. The weakness is that the thermal shock resistance is poor and the moisture resistance is low. It is China's largest production of a variety, accounting for about 2/3, widely used in a variety of motors, electrical appliances, instruments, telecommunications equipment and household appliances.
    4, polyesterimide overcoated with polyamide imide enamelled Xianmi layer is widely used in domestic and foreign heat resistant paint coated wire, the heat level is 200, the product has high heat resistance, resistance to refrigerants, cold resistant, radiation resistant properties, high mechanical strength, stable electrical properties, chemical resistance and resistance to refrigerants good performance, strong overload capacity. Widely used in refrigerator compressors, air conditioning compressors, power tools, explosion-proof motor and high temperature, cold, radiation resistance, overload and other conditions of the use of motor, electrical appliances.
    5, polyester / polyamide imide enameled wire, thermal class 180 the product good heat shock resistance, softening breakdown resistance high temperature, excellent mechanical strength, solvent resistance and refrigerant performance were good, weakness is easy to hydrolysis under closed conditions, widely used in motors, heat high requirements of electrical appliances, instruments, electric power tools dry transformer winding.
