This Silk covered litz wire undergoes strict control during the production process to ensure its quality and reliability.
1.High-quality ultra-fine enameled copper wire is selected as the raw material. This wire is thin and soft, and has good welding performance, which can ensure the smooth conduction of current.
2.Through the stranding process, 300 strands of thin wires are twisted into one wire, making the Litz wire highly flexible and tensile strength, which is convenient for wiring installation and maintenance.
The nylon jacket also reflects the advantages of its products, it provides good wear resistance and cut resistance, allowing the silik covered Litz wire to be used in harsh industrial environments and preventing the wire sheath from being damaged by external factors. For special needs, polyester yarn and real silk are also optional materials to meet the needs of different industries.
Silk covered litz wire has a wide range of uses in industry. It plays a key role in electronic equipment manufacturing, communication equipment, automobile manufacturing, aerospace and other fields.
