Magnesium High Potential Anode

Power in galvanic cathodic protection is generated by the anode. With Corrpro’s line of high potential anodes, you get the most powerful protection available today. Cast from high-purity magnesium, these anodes produce an open circuit potential of 1.75-1.77 volts, which is 20-30 percent greater than conventional magnesium anodes. This high driving voltage means greater protection can be delivered from fewer anodes. Efficiency of the anode is enhanced even further when installed in a backfill of 75% gypsum, 20% bentonite, and 5% sodium sulfate. This special mixture lowers anode-to-earth resistance, and allows electrical current to flow more easily to the targeted structure. 

Corrpro's high potential anodes are available pre-wired with either TW or THHN black wire, in solid or stranded configurations. Standard wire lengths include 10, 20, and 25 feet. Custom wire type, color and lengths avaiable.
