High Potential Buried Magnesium 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 negative 1.75-1.77 volts (CSE), which is 20 to 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 percent gypsum, 20 percent bentonite, and 5 percent sodium sulfate. This special mixture lowers anode-to-earth resistance, and allows electrical current to flow more easily to the targeted structure. Corrpro certified high potential anodes are manufactured according to ASTM B843 and strict quality control standards. Each production run of high potential anodes is subject to G-97 analysis. This ensures the anodes you purchase will perform as specified.
Certified high potential anodes are manufactured in a variety of dimensions and weights. To order the required anode for your structure, indicate that you need high potential magnesium anodes, and specify the quantity desired, the anode type and whether they should be packaged or bare.
The anodes are shipped standard with 10-ft. - #12 AWG solid lead wire with black TW insulation, unless otherwise specified.
