USTC/ETFE/PI/PET Copper Litz Wire 0.07mmx2600 Nylon Serving Litz Wire For High Frequency Transformers
The Nylon Serving Litz Wire is designed for high-performance winding applications that require stable conductivity and dependable insulation. It features 0.07 mm polyurethane enameled copper single-core that is solderable for easy assembly. Inside, the conductor is built with 2600 twisted strands, forming a fine litz structure to help improve current distribution and reduce AC loss in frequency-sensitive designs.
For mechanical protection and long-term reliability, the litz bundle is wrapped with a nylon serving layer. This outer layer enhances abrasion resistance and provides consistent insulation performance during manufacturing and operation.
To better match different application requirements, we also offer advanced alternatives, including PI taped litz wire, PET mylar litz wire, and ETFE triple insulated litz wire. Each wire type supports customization, so you can choose the insulation system that best suits your winding environment, handling needs, and electrical performance requirements.
Quick comparison of use cases:
· Nylon serving litz wire: Ideal for general high-frequency transformers and inductors where balanced insulation, flexibility, and abrasion resistance are key.
· PI taped litz wire: Best for higher temperature and more demanding insulation durability, commonly used in industrial and power electronics.
· PET mylar litz wire: Suitable for cost-effective insulation thickness and stable dielectric properties for many coil products.
· ETFE triple insulated litz wire: Designed for strong protection and harsh environment resistance, especially when additional insulation layers are needed.
We support small-batch customization with MOQ 20 kg, helping you move from R&D to production efficiently.
Main Applications
Used in high-frequency transformers, inductors, wire-wound coils for power converters, chargers, EMI-sensitive circuits, and precision electromagnetic components, including audio and RF winding where low-loss performance and reliable insulation matter.
