Conductor Bar Systems

Paul Vahle patented the original conductor bar in 1912 when he created the steel copperhead conductor bar system. This conductor bar system is still in use today.

Conductor bar systems are known by a variety of names including but not limited to:

Buss Bars, Conductors, Conductor Bars, Powerail, Buss Bars, Conductor Rail, Trolley Bar, Trolley Duct, Hot Rail, & Enclosed Rail

The main function of a conductor system is to transfer electricity from a stationary source to a mobile user (mobile electrification systems). Stationary conductor rails are mounted along the path of a vehicle that requires electric power. The stationary conductors are connected to a main power source. A current collector is mounted on the moving vehicle and is installed to make contact to the electrified conductors. The current collector is comprised of electric brushes that feed electricity into wires powering the vehicle. The concept is similar to track lighting except that with track lighting the lights don’t move. For our systems the vehicle can move while picking up power from the conductor rails. Or can also stand still. The moving vehicle can be anything from a vehicle on an amusement ride, a crane unloading a ship, to production carriers on an assembly line.

Copperhead Conductor Systems

these are conductors mounted on insulators. The current collector assemblies are spring loaded and track along the surface of the conductor bar. These systems are typically used for applications with one or several of the following requirements: hi-speed, hi-amperage requirement, extreme heat conditions, or very dirty environments. Examples include transfer cars in coking operations, crane runways in steel mills, people movers. Individual conductors installed on insulators for high amperage / high voltage heavy duty applications. Systems: Steel-Copperhead, Aluminum-Copperhead, Fiberglass-Copperhead.

Enclosed Multiple Conductor Systems

These systems feature multiple conductors, typically copper strips, in an insulated enclosure. The current collector tracks inside the enclosure with the connecting electric cable connected via an opening (slot) in the bottom of the enclosure. The bottom opening can be sealed with a neoprene sealing strip to keep debris and fumes out. The current collector is self guided in these systems and only needs to be towed with a towing arm. Multiple copper conductors in an enclosure (aluminum or PVC housing). Available in 4 to 11 conductors and amperage capacities from 30 to 300+.

Heavy Enclosed (Trench) Conductor Systems

These systems feature a heavy duty enclosure for open conductors or high voltage systems. We also offer a trench cover plate system with a lifting arm so any of our conductor systems can be installed in a covered trench below the floor level. Typical applications for heavy enclosed conductors include STS, Ship to Shore, cranes, gantry cranes, transfer cars in foundries and coil transfer cars. Any of VAHLE's conductor systems can be used in a heavy enclosed system. The system features cover plates and lifting bogies for trench systems and heavy duty enclosures for above ground systems.

Unipole Insulated Conductor Systems

These individual insulated conductors are assembled in touch safe housings. Any number of conductors can be used side by side or stacked to accommodate as many power lines as are required. We offer a number of different insulated conductors for a variety of mobile electrification applications. Many of these systems can be field modified to accommodate curves, switches, control zones, etc. Individual copper conductors in a PVC housing. Can be stacked for multiple poles. optional galvanized steel, stainless steel, aluminum-stainless steel conductors.

Can be stacked for multiple poles. optional galvanized steel, stainless steel, aluminum-stainless steel conductors.

Slip Rings

Electrical slip rings are shaft-mounted conductive circles or bands. They allow for the uninterrupted transfer of electrical current from stationary to rotary equipment, such as rotating platforms, packaging machinery and cable reels. Standard components of proven unipole or multipole conductor systems make up special curved units.
