HJ Bar

Hybrid Aluminum/Stainless Steel Conductor System

HJ-Bar combines the high conductivity of aluminum with the corrosion resistance and durability of a stainless steel cap into a single conductor bar. Unlike other aluminum/steel designs that use aluminum conductors bolted to standard steel rail to improve electrical performance, HJ-Bar optimizes the aluminum/steel electrical interface through a proprietary manufacturing process that provides continuous contact pressure along the entire length of the rail. This design results in a lightweight, durable and low-maintenance conductor rail.

Features

• Patented manufacturing process ensures low electrical resistance between aluminum and stainless steel components through continuous contact pressure
• Full range of standard components including hangers, anchors, feeders, splice joints, expansion joints, isolation joints and collector assemblies
• Service-proven stainless steel cap design yields high strength without shifting or peeling from the aluminum bar, even under extreme loads
• Hard 3/16” thick stainless steel running surface for extended life under continuous use
• Systems are engineered to customer specifications, including system layout and installation support
• No cleaning or conditioning of the conductor surface required for infrequent use situations
