INSULATED JOINTS
Insulated Joints provide rigid unitized structures designed to withstand years of heavy-duty service, provide high-dielectric isolation for signal circuits, and require little to no maintenance.
POLY - INSULATED JOINTS
A&K insulated rail joints contain tough polyurethane bonded to micro-alloy joint bar sections. This provides reliable circuit isolation and maintains electrical and physical stability in heavy rail traffic. A&Ks polyurethane is a specifically formulated compound highly resistant to deterioration by ultra-violet ozone, weathering abrasions, or the shock and flexing stress of heavy rail traffic. The dense polyurethane material is firmly bonded to the entire rail joint and provides superior insulation between the joint and the rail. Designs are available up to 141 lbs and meet AREMA specifications.
BONDED INSULATED JOINTS (BIJ)
A&Ks Bonded Insulated Joints are manufactured in accordance with AREMA specifications. Typical joint lengths range from 13' to 40,' and we supply longer custom lengths to meet your requirements as needed. We assemble our bonded insulated joints with new and relay rails in various sections. Other options include standard fiberglass or high-strength Kevlar installations, 6 hole 36" or 8 hole 48 " bonded insulated joint bars, and hex bolts with hex nuts or huck pins. The standard end post is 3/16" thick for a 90-degree straight cut. Custom end posts can be supplied as well.
