This prepackaged magnesium anode is composed of a cast magnesium anode centrally packed in a permeable cotton bag with a highly hygroscopic backfill containing a 75% gypsum, 20% bentonite and 5% sodium sulfate mix. Typically this assembly is then firmly wrapped in a PE bag or paper outer lining, for shipping purposes, which should then be removed prior to installation.Efficiency of an anode can be further enhanced when pre-packaged in this depolarizing backfill. The specialized mixture lowers the anode-to-soil resistance, and allows electrical current to flow more easily to the targeted structure.Our magnesium anode is assembled with the cable and joints sealed in with epoxy resin. Designed to meet the fast-paced and high-efficiency requirements of engineering construction, these prepackaged magnesium anodes are often used for the cathodic protection of buried metallic structures in a range of soil resistivities; such as pipelines, underground tanks and external tank bases as well as other similar structures.
Application:Pipelines, Foundations, Storage Tank
