Rolling Stock Wire Harness

Electric Wire & Cable Business Unit


With rich experience in producing rolling stock cable, Proterial manufactures railway harnesses utilizing our innovative harness production line in the Czech Republic.

Our harness production line is fully digitalized. This helps improve production operators' productivity (through paper-less instruction), reduces production time and eliminates human mistakes in manufacturing complicated harnesses (including harnesses with connectors/terminals used in driver's cabs and long harnesses for lighting, power socket, under-floor, and cubicles used in passenger cars).

Our technology can contribute to your project in terms of shorter lead times, cost savings, and higher reliability.

Taking advantage of digital data, our harnesses feature an information-embedded label with a QR code containing a serial number for traceability and electrical circuit information for every wire end.

Symbols or numbers as reference points for the installation root can also be added to harnesses to reduce wire installation time. Please consult us regarding any other information you may wish to add to harnesses.

We manufacture various types of harnesses with connectors / terminals and protective covers assembled to meet different needs and applications. Our wiring technology adds value to any kind of rolling stock and buses.
