litz wire served with one or two layers of natural silk, nylon or polyester fibers around the outer layer. This ensures a more stable overall diameter and provides better protection for the enameled wire, preventing damage to the enamel coating during winding operations.
Benefits of Using Served Litz Wire：
Served litz wire meets all the performance characteristics of standard litz wire while offering additional protection with the silk layer, making the wire more suitable for mechanical winding processes. The overall diameter stability of the wire is improved.
The increased distance between individual wires enhances the insulation of the product, reduces the capacitance between winding layers, increases the Q-factor of the product, and lowers the temperature rise.
