Magnesium in Backfill
Of all available anode material, magnesium is the one who has the highest driven voltage. Because of this, magnesium anodes are used advantageously in soil and water with high resistivity.
Normally there’s two different qualities being used, standard potential ( 1.5V ) and high potential (1.7V). When the anodes are intended for land installation, they are delivered as standard with a backfill mix of bentonite, as well as 5m long red XLPE/PVC 6mm2 cable.
The cable connection is embedded in epoxy.
Backfill: Plaster 75%, Bentonite 20%, Sodium sulfate 5%
