we attach a copper lead wire (size, length and insulation type as specified) to the H-1 anode and seal the connection interface. If required, the H-1 anode will be packaged in a cloth bag with prepared backfill mixture of 75% gypsum, 20% bentonite and 5% sodium sulfate. The backfill mixture works to maintain moisture around the anode and lowers the anode to earth resistance. The packaged anodes are shipped on pallets in plastic bags that must be removed prior to installation.

Application:
In cathodic protection, the most widely used sacrificial anodes are magnesium anodes. When high potential magnesium anodes are required for high current application
Mg anode is manufactured from high purity primary magnesium under strict, state of the art production techniques, anode chemistry, testing and certification
