2USTC-H 60 x 0.15mm Copper Stranded Wire Silk Covered Litz Wire
The outer layer is wrapped in a durable nylon yarn, while the inner litz wire consists of 60 strands of 0.15mm enameled copper wire. With a temperature resistance level of 180 degrees Celsius, this wire is engineered to perform reliably in high temperature environments, making it an ideal choice for a wide range of applications.
Customization is at the heart of our products. We understand that different projects require different specifications, which is why we support full customization of our silk covered stranded wire. Customers can choose the size of the individual wires, ranging from 0.025mm to 0.8mm in diameter. Additionally, the number of strands can be customized based on specific requirements, with up to 12,700 strands available. This level of customization ensures that our customers receive a product that is exactly what their project requires, whether they are designing a transformer, coil, or hi-fi audio cable.
In addition, we offer the option of using silver conductors for the strands, further enhancing the performance of our silk covered stranded wire. Silver is known for its exceptional conductivity, making it an excellent choice for applications where electrical performance is critical. By combining silver conductors with the luxurious silk covering, we offer a product that not only excels in performance, but also stands out in terms of quality and craftsmanship.
