High Potential Magnesium Anode |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| INTRODUCTION High potential magnesium anodes are 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 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 structures. The anodes are packed standard with 3 meters of 8 sq. mm (AWG#8) HMWPE wire. Different length, sizes, or types of cable such as XLPE, PVC, HALAR is available upon request. APPLICATION High potential magnesium anodes are used to protect buried metallic structures found in a range of soil resistivities. Because they produce a higher driving voltage than conventional magnesium anodes, they are ideally suited for structures buried in soils with resistivities in excess of 2,000 ohm/cm or containing numerous corrosion" hot spot¡¨. |
