Highest Quality & Safety

Our high-voltage wiring harnesses are designed for demanding applications:

Individually

Custom configurations for every vehicle class and industry

Quality

100% tested production, EMC and safety testing

Process efficiency and reliability

Our lean and transparent processes enable fast response times and on-schedule deliveries. With continuous in-process quality control, we ensure you can rely on our products at all times.

Innovative Manufacturing Expertise

We combine state-of-the-art CNC crimping and ultrasonic technology with precise manual workmanship. Every cable is individually inspected, taped, labeled and wired. Automated end-of-line test benches as well as thermal and EMC testing ensure durable and safe solutions for all high-voltage projects.

Specialised, precise cable processing
We use technology designed for processing highly insulated, shielded high-voltage cables. As one of the few providers, we can process high-voltage wiring on our highly modern, fully automated machines. This guarantees the utmost precision and safety for your application.

Secure connection techniques
Our experts master all essential techniques, such as ultrasonic welding and soldering, to create extremely strong, gas-tight, and highly conductive connections.

Comprehensive high-voltage testing
Every cable harness is tested on special HV test rigs for dielectric strength, insulation resistance, and partial discharge, guaranteeing compliance with the strictest safety standards.

Our expertise enables both series solutions and custom special products to be implemented efficiently and in compliance with all standards.

FAQ

What advantages do your high-voltage cable harnesses offer compared to standard products?

neered solutions specially developed for demanding applications. With state-of-the-art technology like crimp force monitoring and ultrasonic welding, we guarantee maximum safety, longevity, and performance—often far beyond what standard products can deliver.

Safety is our top priority. Every cable harness is thoroughly tested on specialised high-voltage test benches. We check for dielectric strength, insulation resistance, and partial discharge in line with the strictest safety standards. Only certified materials are used, and every production step is completely documented.

Absolutely. Many projects start with prototypes. As a flexible partner, we not only develop and manufacture large production runs but also prototypes and small batches. Our co-engineering approach means we can get involved early in the development process to create the optimum solution for your specific needs.
