Open Conductor Bar Systems

While working in a steel mill in 1912, Paul Vahle began designing more effective and safer methods of mobile power transfer. At the time, the common method was traveling wires which did not provide a secure contact, generated a lot of sparks and broke easily.

The result of his efforts was the original conductor bar and it is still in operation today. The standard version is a copper bar mounted onto a T-Shaped steel beam. The copper bar transfers the electrical current safely while the T-bar provides a robust and reliable mount.
