A High Potential Magnesium Anode (D Type) is a sacrificial (galvanic) anode specifically designed for cathodic protection (CP) of buried or submerged metallic structures in high-resistivity environments. The “D Type” refers to its D-shaped cross-section, which provides improved contact with backfill material and enhances current distribution.
