HF Litz Wires In-House Manufacturing

Family-run. Precise. Reliable.

So that your trust is never a coincidence.

Since 1933, we have been your reliable link between technical vision and real-world performance – Made in Germany. Discover the HF litz wires and fine wires that fit your application precisely.

Tools for Precise Calculations and Reproducible Results

LiWiCalc® and RuPaFox® provide resilient data for the design, efficiency, and reproducibility of litz wires.

Configurator RuPaFox®

Optimize your winding design in just a few steps: RuPaFox® calculates missing values and the total diameter including insulation based on two core parameters. Additionally, the tool provides resistance and weight metrics for reliable technical and logistical planning.

Calculator LiWiCalc®

Simulate power losses and current densities based on real-world high-frequency litz wire manufacturing data. Developed by the Fraunhofer Institute IISB, LiWiCalc® provides a scientifically sound basis to realistically evaluate and specifically optimize HF litz wires for your application.

Industry Expertise through Experience and Development

Our products combine high electrical efficiency with mechanical resilience – specifically tailored to your industrial application.
