Application areas of enameled wire
Enameled flat copper wire applications: relays, micro-motors, small transformers, magnetic heads, precision instruments, coils for communication equipment, suitable for transformers, generators, motors, reactors and a variety of electrical equipment devices winding
240 grade enameled flat wire is widely used in automobile generators, new energy vehicles, electric two-wheeled, three-wheeled, four-wheeled, generators, coal mines, motors, high-speed railways, atomic energy, aviation and other fields.
180 grade enameled flat copper wire is suitable for domestic mainstream motor, transformer, reactor, switch coil market requirements.
Vertical Winding Enameled Flat Wire
With the progress of science and technology, in the past, the round enameled wire was used for poor heat dissipation, large coil estimation area, small power and other problems. With the development of high-end equipment, the enameled wire is required to be wide and flat for vertical winding, in order to achieve the advantages of heat dissipation of each wire and high slot fullness rate, small product size, high power and so on. Widely used in electronics, inductors, cell phone wireless chargers, electrical and other high-end equipment.
Flattened enameled wire-Product use:
1, flattening acetal enameled wire; heat level of i05 and 120 two, with good mechanical strength, adhesion, resistance to transformer oil and refrigerant resistance, but the product is poor moisture resistance, low thermal softening breakdown temperature, durable benzene-alcohol mixed solvent performance and other shortcomings, a small number of oil-immersed transformers, oil-filled motor windings.
2, flattened polyester and modified polyester enameled wire, ordinary polyester enameled wire, the heat level of 130, after modification of the enameled wire heat level of 155. The product has high mechanical strength, and has good elasticity, scratch resistance, adhesion, electrical properties and solvent resistance, it is a variety of China’s production volume, accounting for about two thirds: widely used in a variety of electric motors, electrical appliances, instrumentation, telecommunication equipment and home appliances; the product’s weakness is the poor performance of the thermal shock resistance, moisture resistance is low.
3, flattened polyurethane enameled wire; heat level rating of 130.155.180. Great features are straight welding, high-frequency resistance, easy coloring, moisture resistance, widely used in electronic appliances and precision instruments, telecommunications, instrumentation, the weakness of the product is the mechanical strength of a little worse, heat-resistant, and the production of large-size line of flexibility and adhesion of the poor, so the specifications of the production of small and medium-sized and micro-fine line is more. Micro-fine line is more.
4, flattened polyester imide enameled wire, heat level 180 the product has good thermal shock resistance, high softening breakdown temperature, excellent mechanical strength, solvent resistance and freezing agent resistance are good, weakness is easy to hydrolyze under closed conditions, widely used in heat-resistant requirements of the motor, electrical appliances, instrumentation, power tools, power dry presses and other windings.
5, compressed polyester imide, polyamide imide composite layer enameled wire in China outside the use of more widely used heat-resistant enameled wire, the heat level of 200, the product is highly heat-resistant, but also has the resistance to freezing agents, cold, radiation and other characteristics of the high mechanical strength, electrical properties are stable, chemical resistance and resistance to freezing agent performance is good, overloading capacity. Widely used in refrigerator compressor, air conditioning compressor, power tools, explosion-proof motor and high temperature, cold, radiation resistance, overload and other conditions used in the motor, electrical appliances.
In short, enameled wire has good insulation properties, high temperature resistance, chemical resistance and flexibility, making it widely used in various fields.
