Conductor Bar Systems

Conductix-Wampfler Conductor Bar Systems for crane electrification and other mobile equipment.

Additional information


Conductor bar is a safe and economical method to provide electric power to mobile equipment. We were the first to offer "8-bar" insulated conductor bar for crane electrification in the US back in 1952.
Now you can choose from six unique systems for virtually any need from 100 to 1500 amperes and more.  We've manufactured the brands you have trusted for the past 60 years:  Insul-8, Wampfler, and Saf-T-Bar - now part of the Conductix-Wampfler conductor bar family.

Safe-Lec 2 Conductor Bar

Additional information

SAFE-LEC 2 ®  V-Contact Conductor Bar System - the new standard in overhead crane electrification.  SL 2 is ideal for monorail and material handling system electrification as well.

Safe-Lec 2 provides these great benefits:

  • Positive Tracking - "V-contact" in the bar guides the shoe and provides continuous conductivity.  Collector arms articulate in a wide range of motion to help keep the collector shoe in contact with the rail.
  • Safe Insulation -  Conductor bar is insulated for IP2 "finger-safe" operation.
  • Bolted Splice - a postive connection that cannot pull apart over time.
  • Minimum Number of Unique Parts - same cover profile fits all bar styles!
  • Easy System Configuration - using our advanced "Quick Quote" software.

Product data

Safe-Lec 2 is easy to install

  • Multiple-Pole Hangers - holds 3 or 4 bars and install with a single bolt
  • Fewer splice joints - 14.75 foot (4.5 Meter) bar length versus the usual 10 foot.

Hevi-Bar II Conductor Bar

Additional information

The Conductix-Wampfler Hevi-Bar II Conductor Bar System delivers the kind of reliable, high-capacity crane rail electric service needed by factories, mills, storage yards, people movers, and other rigorous applications.

Hevi-Bar II features:

  • Effective Heat Dissipation - uses surface area rather than mass to dissipate heat generated by high current conditions
  • Mounting versatility - can be mounted with the bars next to one another (horizontal) or one above the other (vertical)
  • A choice of Insulating Covers - standard orange PVC, green PVC for the bonding (ground) conductor bar (500 amp only), black UV-resistant PVC for outdoor use, and medium or high heat versions to withstand higher ambient temperatures
  • Ease of Installation - a limited number of modular components
  • Low Maintenance and Long Life - this is truly an "install it once and forget about it" conductor bar system
  • Easy System Configuration - using our advanced "Quick Quote" software!

Product data

Current Capacity Range:

500 amps, 700 amps, 1000 amps, and 1500 amps, at 600 volts.
Maximum Running Speed:

2,000 feet/minute (609.6 meters/minute)


  • Heater wire systems (500 amp only)
  • Stainless steel hardware
  • Green bonding (ground) conductor covers, black "UV resistant" outdoor covers, and high-heat covers
  • Curved systems - Contact the Factory

DURA-COAT - For Corrosive Environments

Hevi-Bar II is available with our optional DURA-COAT finish. Dura-Coat is a specially formulated coating that combines a ceramic compound with an epoxy binder to provide superior corrosion resistance and adhesion to the base materials. The entire bar is coated except in the stainless steel collector shoe running area; the insulating cover is applied over the coating.

All metal parts of the collector arm are coated. Arms are not coated as they are made from high-strength glass filled polymer.

DURA-COAT is an ideal conductor bar for galvanizing and electro-plating lines, chemical plants, smelters, foundries and cast houses, coke and ore handling cranes, and oxidizing/electro-winning facilities.


Insul 8 8-Bar Conductor Bar

Side-Contact Conductor Bar

Additional information

Conductix-Wampfler Side Contact Conductor Bar is a variation of the 8-Bar system designed for lateral (side) entry of the collector. UL / CSA listed.

  • Come with cover and connector pins installed. Copper and Laminate Bars also come with Joint Keepers.
  • Have expansion sections that are required for every 350 feet (106.7m) for 40, 90, and 110 amp systems, or 250 feet (76.2m) for 250 or 350 amps to compensate for thermal expansion.
  • Are easy to configure using our advanced "Quick Quote"software!
