The Mitigator is the industry’s only engineered AC mitigation system to combat the corrosive effects of alternating current (AC) on pipelines, combining performance with greater ease of installation and lower cost. Providing superior performance over bare copper and zinc for AC grounding and mitigation, this system is based on MATCOR’s SPL™-Anode manufacturing technology. It is a packaged grounding system that combines the best of copper grounding with low resistance, corrosion-inhibiting backfill.
The Mitigator utilizes a multi-strand copper cable, encased in low resistance backfill with corrosion inhibitors, and then encased in a tough fabric sleeve wrapped with MATCOR braiding for greater strength. The system is provided in standard 500 and 1,000 ft. lengths. See the specification chart for additional information.

The Mitigator AC Mitigation System Components
Engineering Drawing »The MITIGATOR is a ready to install AC mitigation system that includes:
- Continuous stranded copper conductor for the length ordered
- Low resistance, machine compacted backfill with copper corrosion inhibitors
- Durable, non-degrading fabric wrap
- Color-coded outer braiding for easy identification of the grounding system
- Shipped on a reel for easy installation
The MITIGATOR AC Mitigation System Design
The Mitigator can be easily customized for your continuous grounding system requirements. For most applications, standard AWG No. 2 internal copper cable is sufficient. When packaged in MATCOR’s backfill and housing, cable performance is greatly enhanced.
Contact MATCOR engineering for additional help or for total project design. If the previous use has been zinc ribbon, see the specification chart for Mitigator replacement sizes.
The MITIGATOR AC Mitigation System Installation
The Mitigator can be installed several ways, including horizontal directional drilling (HDD), cable plow and trenching. This is a tough product that can be buried directly in the soil without additional special backfill. When installing the via HDD, MATCOR recommends using the AWG No. 1/0 continuous copper cable for greater strength.
Specifying and Ordering The MITIGATOR AC Mitigation System
Simply specify the length and internal copper cable size when you order. Also available from MATCOR are solid state decouplers, connecting cables, junction boxes, reference electrodes and test stations. MATCOR engineering is ready to assist with your design and product selections.
