Enamel polyester wire wrapped with Leeds wire is a winding wire that combines the characteristics of enamel wire and Leeds wire. Its characteristics and uses are as follows:
>> Characteristic
1. High frequency performance optimization
The Leeds line can effectively reduce skin effect and proximity effect in high-frequency environments by twisting multiple independent insulated conductors, reducing power loss and electric field concentration problems. The outer layer is wrapped with polyester yarn, further enhancing insulation performance and mechanical strength, suitable for high-frequency application scenarios.
2. Heat resistance and mechanical strength
Polyester fiber, as an insulating material, has good heat resistance (usually above 155 ℃) and mechanical strength, as well as chemical corrosion resistance and wear resistance
Combined with the insulation protection of the enamel coating, the overall weather resistance and service life are enhanced.
3. Flexibility and process adaptability
The polyester filament winding process can adapt to complex winding requirements, such as skeleton free coils or micro fine wire structures, and is easy to achieve self adhesion through heating or solvent treatment, simplifying the winding process
>> Main Purpose
1. High frequency electrical appliances and equipment
Widely used in high-frequency transformers, inductors, frequency converters, communication equipment (such as radios, induction heaters), and ultrasonic equipment to solve energy loss and electromagnetic interference problems under high-frequency currents
2. Industrial and Power Systems
Suitable for electric motors, generators, fuel cells, and high-voltage motor windings, especially outstanding in harsh environments that require high temperature resistance and chemical corrosion resistance
3. Consumer Electronics and Home Appliances
Used for devices such as speakers, headphone coils, televisions, and microwave ovens, balancing high-frequency performance and mechanical stability
Summarize
The enameled polyester filament wrapped Leeds wire has significant advantages in high-frequency performance, heat resistance, and mechanical strength through a composite insulation structure, making it an ideal choice for high-frequency electrical appliances, industrial equipment, and consumer electronics
