There are different kinds of enameled wire. But what are the features of different classification. Now let our Zhengzhou LP Industry Co., Ltd introduce about this point.
(1) Acetal enameled wire: There are two heat level of 105 and 120. It has good mechanical strength, adhesion resistance, transformer oil and refrigerant resistance performance. But poor performance of the product resistant to moisture, heat Softening temperature is low, durable benzene - alcohol weak performance defects such as a mixed solvent, and now only a small amount for oil-immersed transformers, oil-filled motor windings.
(2) Polyester and modified polyester enameled wire: Ordinary polyester enameled wire, thermal level is 130. And the modified enameled heat level is 155. The product has high mechanical strength and good elasticity, scratch, adhesion, electrical properties and solvent resistance, which is China's current production capacity of the largest species, accounting for about two-thirds: widely used in various motors, electrical, instrumentation, telecommunications equipment and home appliances. But the weakness of product is poor thermal shock resistance, low moisture resistance properties.
(3)Polyurethane enameled wire: Heat level rates 130,155,180,200. The biggest feature is a linear welding resistance, high frequency performance. And it is easy to be colored. It also has good moisture resistance performance, widely used on electronic appliances and precision instruments, telecommunications, instrumentation, mechanical strength. The weakness is low heat resistance, bad production flexibility and poor adhesion of large-size line, so the product's specification is always medium or fine wire.
(4)Polyester-imide / polyamide enameled wire: thermal level is 180. The product has high shock resistance, high temperature softening breakdown, good mechanical strength, solvent resistance and refrigerant properties. The weakness is easy to hydrolysis in the closed condition.it is widely used for high heat-resistant electrical, electronics, instrumentation, power tools and other power dry-pressed winding.
(5) Polyester-imide / polyamide-imide enameled wire is currently more widely used in the world. The heat level is 200. The product has high heat resistance, anti-freezing agent, resistant to cold, excellent radiation-resistant properties, high mechanical strength, electrical performance and stability, good chemical resistance, resistance to freezing agent performance and strong overload capability. It widely used in the next refrigerator compressors, air conditioning compressors, power tools, explosion-proof motors and heat, cold, radiation-resistant, overload conditions such as use of electrical, electronics.
