Open Conductor Bar System

Open conductor bar systems are designed for high-current industrial applications that require maximum durability and conductivity. These exposed conductor rails are ideal for heavy-duty crane electrification, gantry systems, steel mills, shipyards and other harsh outdoor environments.

As the inventor of the first copper busbar, VAHLE brings more than 100 years of engineering expertise to the development of robust conductor rail technology.

VAHLE's open conductor rails consist of a T-shaped steel support profile combined with a high-conductivity copper contact surface. This robust construction ensures reliable power transmission and secure contact with the current collector — even under extreme mechanical stress.

For applications where weight reduction is important, light metal variants are available. For particularly high current requirements or damp operating environments, solid copper conductor rails provide enhanced performance and long service life.

Engineered for flexibility, these systems can be adapted to curved tracks, variable suspension designs and complex crane runways. This conductor bar system can withstand the harshest environments — from high temperatures in galvanizing plants to dust and humidity in port operations. With minimal wear on copper components and excellent thermal resistance, open conductor bar systems remain a cost-effective solution for long-term industrial operation.
