Specification :

Above bare Mg anodes could be supplied after being prepackaged. The bare Mg anodes will be assembled with cable and sealed with epoxy resin, and packaged in cotton bag.

As the prepackaged anodes are buried under the ground, if there is any harmful element in the backfill of prepackaged anodes, this element will leak to the earth and groundwater when the anode is in use, which will pollute the environment.
