AC Mitigation Ribbon (Carbon Backfill)
Pipeline corrosion, caused by induced AC current, is attributed to high voltage AC power lines in close proximity to a pipeline system. The corrosion can be extremely aggressive, far exceeding the normal corrosion rate caused by corrosive soils. One of the most popular mitigation solutions is a linear grounding system that is installed in parallel to the pipeline.
Compared with bare copper and zinc ribbon, this long-line “cable” is a superior grounding material that provides an effective electrical path to remove or discharge AC current from the pipeline to the ground. It is comprised of a bare stranded copper conductor encased in low resistance backfill with corrosion inhibitors, and then wrapped in a synthetic sock.

Description
FEATURES
- Low resistivity grounding backfill
- Backfill material contains a corrosion inhibitor for increased life of system
- Larger surface area for better dissipation of induced current
- Excellent electrical performance, better than bare copper and zinc ribbon anode
- Designed for fast, efficient continuous installation process
- Excellent earth contact
- Easy field splicing
APPLICATIONS
This AC mitigation ribbon can be installed in several ways, including horizontal directional drilling, cable plow and trenching. It is a tough product that can be buried directly in all kind of soil, especially well suited the environment where the resistivity is high or various, and where there are risks for interference with secondary structures.
Our AC mitigation ribbon is commonly applied to pipeline grounding systems or structure that are subject to AC interference.
- Prevent voltage spikes during fault conditions
- Reduce AC-induced corrosion
- Maintain AC step and touch potentials to protect personnel from shock hazards
