Extrusion

Extruded coatings applied to high frequency litz wires promote increased flexibility, mechanical robustness, resistance to chemical substances, as well as increased break down voltage. The flex life performance of extruded litz wire is also improved considerably in comparison to standard constructions. Extrusion materials, wall thickness tolerance, and litz wire construction can be selected and combined for optimal performance in a wide range of applications.
