Conductor Bar Systems
Conductor bar systems were developed as a safe and reliable way to transfer electricity from a stationary source to a mobile consumer. They are often used for crane electrification and other equipment. Conductor bars are mounted along the path the mobile consumer will follow and a current collector is mounted onto the moving vehicle. This current collector maintains contact with the conductor bar as the vehicle operates allowing the flow of electricity.
The original conductor bar was patented in 1912 by Paul Vahle, beginning over 100 years of expertise in mobile power solutions. Today, this original conductor bar is still in use along with a variety of evolutions engineered by VAHLE for any application.
Types of Conductor Bar Systems
The original conductor bar designed and patented by Paul Vahle. These are conductors mounted onto insulators with spring loaded current collectors that track along the surface of the conductor bar. VAHLE’s largest and most robust power solution these systems excel in applications that require hi-speed, hi-amperage and voltage and operate in harsh environmental conditions. Typical applications include coking operations, steel mills and people movers.
Enclosed conductor bar systems are a unique specialty offered by VAHLE. Up to 11 conductors can be placed inside an insulated compact housing with an internal guided current collector. This allows for additional mounting opportunities, increased personal safety and operation in a variety of hazardous environments. 6 models are currently offered by VAHLE with unique features and benefits for your specific application. Additionally specialty sections and accessories offer additional opportunities for various markets.
VAHLE offers a wide range of individual insulated conductor bars. Each type is housed in a touch safe insulated housing and can be offered with a variety of conductor material such as copper, stainless steel or aluminum. Any number of conductors can be installed side by side or stacked to accommodate any application or requirement. Curves, switches, control zones, etc. are also possible and many custom sections can be modified on site.
These systems combine VAHLE’s proven conductor bar solutions within a heavy duty enclosure for additional protection, typically used with high voltage systems. Common applications include ship to shore cranes, large mill or production cranes, foundries and coil transfer cars. These systems feature cover plates and lifting bogies for floor mounted or heavy duty enclosures for above ground.
Load bearing systems used in conjunction with standard VAHLE conductor bar systems. Typically installed in parallel with conductor bar, these systems can be used in production areas with moving work stations or testing lines.
Conductor rings allowing for the uninterrupted transfer of electrical current from stationary to rotary equipment. Created using standard VAHLE conductor bar custom curved to your application. Typical applications include rotating platforms, packaging machinery and cable reels.
