Open conductor system

With the invention of the first copper conductor system, Paul Vahle laid the foundation for our success story, which has now spanned more than 100 years. To this day, our light metal or solid copper conductor systems are used wherever moving industrial applications need to be supplied with power in particularly harsh environments.

VAHLE open conductor systems consist of a T-shaped steel base covered with a copper profile. The resulting high mechanical strength ensures safe and reliable contact with the current collector. We also offer a light weight metal option. For high currents and especially in humid environments, we recommend the use of our proven solid copper rails.

Our versatile open conductor systems can be adapted to meet your specific track layout, including suspended and curve tracks. The conductor systems withstand even the harshest conditions such as frost or extreme heat. Since the copper components hardly show any wear, these systems are particularly durable and economical.

Despite their light weight, our open conductor systems are characterized by optimum conductivity, high load-bearing capacity and incomparable robustness. Whether in the heat of iron and steel mills, the humidity of shipyards and harbors, or the dusty environment of coking plants and cement works, our products keep things moving where other systems reach their limits.
