2USTC-F 0.1mmx100 Silk Covered Litz Wire For Transformer
This is a custom nylon served litz wire with a single wire diameter of 0.1 mm. This single wire is one of the most commonly used wire for silk covered stranded wire. We can produce polyurethane-enameled copper wire with single strand diameters ranging from 0.03 mm to 0.5 mm and can fully customize it to your specific needs. This specialized wire is made of 100 strands, offering excellent flexibility and performance.
·IEC 60317-23
·NEMA MW 77-C
·customized according to customer requirements.
Silk covered litz wire is a valuable asset in industrial areas, motor and transformer applications, and wireless charging systems. Its ability to minimize skin effect and handle high-frequency currents with minimal power loss makes it an important component of high-performance electronic systems. With its customizable features and superior performance, silk covered litz wire will continue to make significant contributions to various industrial and technological advancements.
Regarding no of strands, we can produce single-strand conductors with up to 12,700 strands, depending on the appropriate single wire diameter. If you have specific design and customization requirements, please let us know and our technical team will be happy to assist you. The minimum order quantity for this type of conductor is typically 20 kg, but we also offer custom orders in smaller quantities to accommodate various project sizes.
This type of silk covered litz wire is primarily used in transformer windings. In transformer applications, stranded wire is crucial for minimizing eddy current losses, thereby improving overall efficiency, especially at high frequencies. Its unique structure allows for improved thermal management and flexibility, making it ideal for a variety of industrial applications, including power transformers, inductors, and other electromagnetic devices. By using this type of wire, manufacturers can improve product performance and reliability, ultimately increasing energy efficiency and reducing operating costs.
