Acetal enameled wire ; thermal grade of 105 and 120 are two kinds, with good mechanical strength, adhesion, resistance to transformer oil and refrigerant resistance, but the product is poor moisture resistance, thermal softening breakdown temperature is low, durable benzene – alcohol mixed solvent Weak performance and other defects, only a small amount for the oil-immersed transformer, oil-filled motor windings.
Polyester and modified polyester enamelled wire, ordinary polyester enameled wire, the heat level of 130, the enameled wire after the heat-modified grade of 155. The product is high mechanical strength, and has good flexibility, scratch resistance, adhesion, electrical properties and solvent resistance, it is currently China’s largest production of a species, accounting for about two-thirds: widely used in a variety of motors, Electrical appliances, instruments, telecommunications equipment and home appliances; the weakness of the product is poor thermal shock resistance, low resistance to moisture.
Polyurethane enameled wire; thermal grade of 130.155.180. The most important feature is a straight solderability, good high frequency performance, easy coloring, moisture resistance is good, widely used in electronic home appliances and precision instruments, telecommunications, instrumentation, the weakness of the product is less mechanical strength, heat resistance is not high , And the production of large-format line of flexibility and poor adhesion, so the product specifications to small and medium-sized and more.
Polyester imide enameled wire, hot grade 180 The product has good thermal shock resistance, high softening resistance, high mechanical strength, good solvent resistance and cryogenic resistance, weakness is easy to hydrolysis in closed conditions, widely used In heat-demanding motor, electrical appliances, instruments, power tools and other power dry-type windings.
Polyester imide / polyamideimide composite layer enameled wire. At present, at home and abroad more widely used heat-resistant enameled wire, the heat level of 200, the product of high heat resistance, but also has resistance to freezing agents, resistance to cold, radiation-resistant And other characteristics, high mechanical strength, electrical performance and stability, chemical resist.
