Safety on the Rails

Railway technology demands robust components that combine economic efficiency with the strictest standards. Efficient energy transmission and durability are key to modern rail vehicles. HF litz wires from PACK LitzWire help to save weight, optimize heat dissipation, and meet the high safety standards in passenger transport.

Whether in traction transformers, auxiliary power units, or signaling technology – our solutions offer tested insulation systems and long-term stable performance for reliable rail operation over decades.

We supply high-quality HF litz wires to manufacturers for:

  • Power electronics
  • Electric drives
  • Control components
  • Battery chargers
  • Lighting systems
  • Signaling technology & electronics

Safety through Standards and Precision

In railway technology, trust is based on strict compliance with railway-specific standards and the durability of the components.

  • Standard-Compliant Safety
    Our insulation systems are tested for partial discharge-free operation and long-term durability under harsh conditions.
  • Data-Based Design
    With the help of RuPaFox© and LiWiCalc®, we design the number of strands and lay length precisely to your frequency specifications to optimize weight and costs.
  • Complete Process Control
    As an owner-managed family business, we manufacture exclusively in Germany, thus guaranteeing consistently high quality.
  • Individual Parameterization
    We adapt every litz wire exactly to your specifications to achieve the best possible performance for your specific area of application.

Service Life Predictions for Maximum Availability

A long service life is crucial for the reliability of components in railway technology. Failures cause high costs and operational interruptions. That is why we do not rely solely on theoretical assumptions but investigate aging processes under real operating conditions.

In close cooperation with research institutes and customers, we:

  • develop valid service life predictions for various insulation systems
  • verify the accuracy of our litz wire designs
  • optimize the design of components based on data

This knowledge flows directly into your projects. It gives you the confidence to deploy durable systems on the rails that function reliably and with low maintenance even after years in use.

Innovation & Development
Practical Solutions for Rail Transport

The requirements for railway technology are diverse and demanding. PACK LitzWire develops individual solutions in close coordination with customers that push technical boundaries.

High-Current Transformers for Railway Technology
High-Current Transformers for Railway Technology

PACK LitzWire, together with a railway technology manufacturer, developed an optimized litz wire winding for transformers. The challenge was to safely conduct extremely high currents without creating thermal hotspots. By using a high-frequency litz wire system, the current is distributed uniformly, which increases safety while simultaneously reducing component volume.

Long-Term Stable Solutions for the Rails

  • Precise design for partial discharge-free operation and long-term durability.
  • Logistics concepts such as safety stocks and framework contracts for high availability.
  • Validation of your litz wire design through professional simulation tools.
