2USTC-F 0.08mmx270 Red Color Nylon Served Silk Covered Litz Wire
Silk covered Litz wire is a custom-designed wire with a single wire diameter of 0.08 mm. The wire cable is composed of 270 strands of enameled copper wire twisted together, with an outer layer of red polyester yarn.
Custom color services are available, typically using white polyester or nylon yarn.
·IEC 60317-23
·NEMA MW 77-C
·customized according to customer requirements.
The nylon layer plays a crucial role in providing mechanical protection, enhancing the wire’s abrasion and tear resistance. This outer layer not only improves the wire’s durability and extends its service life but also stabilizes the overall diameter of the wire, preventing damage during winding.
The nylon cover provides enhanced mechanical protection, effectively protecting individual enameled copper wires from external damage such as abrasion, bending, and stretching, making the wire exceptionally robust and durable for harsh applications. Furthermore, the nylon layer prevents damage, ensuring long-term stable and reliable performance. During winding, the nylon layer also acts as a protective buffer, minimizing the risk of scratching or damaging the delicate enameled wire. Additionally, the nylon layer helps maintain a stable diameter in the finished Litz wire, which is crucial for applications requiring precise dimensions.Another important function is that nylon yarn has a good adsorption effect during transformer potting.
