2USTC-F Stranded Wire 0.05mm x225 Strands Silk Covered Litz Wire
Silk covered litz wire is a specialized litz wire designed for high-performance applications, in the transformer winding, wireless charge winding, audio cable making etc. This custom silk covered litz wire is customized by an Indian client, it’s used for transformer winding.
This litz wire is wrapped with nylon yarn outside, however, we also offer alternatives such as polyester yarn for clients who prefer different materials, we also provide exquisite natural silk coverings, this type of silk covered litz wire is used for high end audio cable, of course the inner conductor usually are high purity copper or silver.
The silk covered litz wire consists of enameled wire with a diameter of 0.05mm, meticulously twisted together in 225 strands. This intricate design is essential for minimizing AC losses in high-frequency windings, significantly enhancing efficiency.
The primary advantage of using litz wire lies in its ability to mitigate the “skin effect,” a phenomenon that affects how alternating current flows through conductors. By employing litz wire, designers can effectively eliminate this effect, leading to improved performance in their applications.
We understand the diverse needs of our clients, which is why we support small-batch customization with a minimum order quantity of just 10kg. This flexibility allows businesses to experiment with different configurations and materials, ensuring they receive a product that meets their exact specifications. Whether for high-end audio cables or other specialized uses, silk covered litz wire stands out as a premium choice for those looking to enhance their electrical performance.
