UDTC-F 84X0.1mm High Frequency Silk Covered Litz Wire For Transformer
This taped litz wire has a single wire diameter of 0.4 mm, consists of 120 strands twisted together, and is wrapped with a polyimide film. Polyimide film is considered one of the best insulation materials currently, with high temperature resistance and excellent insulation properties. The numerous advantages of using taped litz wire make it a popular choice for magnetic applications in industries such as high frequency transformers, high power transformer manufacturing, and medical equipment, inverters, high frequency inductors and transformers.
The versatility of our nylon served litz wire is one of its standout features. Every customer’s transformer design is unique, and therefore requires a custom winding method. This is exactly where our products shine. We understand that industry demands require flexibility and precision, which is why we offer small batch customization. With a minimum order quantity of just 10 kg, we enable our customers to get the exact specifications they need without the burden of carrying excess inventory. This level of customization ensures that you receive a product that is perfectly suited to your application, thereby increasing the efficiency and reliability of your transformer.
The silk-covered litz wire is particularly useful in applications where performance and efficiency are critical. The unique wire construction minimizes skin effect and proximity effect losses, which are key factors affecting transformer performance. By using our custom silk covered litz wire, you can improve the overall efficiency of your transformer, thereby increasing energy savings and reducing operating costs. This makes our products more than just a component, but a strategic investment in the future of your industrial operations.
