Profiled Litz Wire
Profiled (mechanically shaped) litz wires allow optimal utilization of available winding space due to the superior filling factor of rectangular or square litz wire cross sections. In comparison to a standard round cross section construction, profiled litz wire can increase the filling factor up to 20%.
The design advantages of profiled litz wire can only be fully realized using products with consistent and precise dimensions. This dimensional stability is only possible with exact control of each process step.
- Increased filling factor of up to 20 %
- Constant winding performance requiring tight dimensional tolerance and good flexibility
- Profiled dimensions to customer specification
- Profiling also possible with outer insulation
