De Nora LIDA® PACK canistered wire anodes are the perfect impressed current anode for shallow vertical and horizontal surface groundbeds, as well as wet, marshy soil conditions where caving is likely to occur. Ideal for protecting structures such as:
The primary anode in an De Nora LIDA® PACK is a mixed metal oxide wire anode. The wire anode is comprised of a precious metal oxide coating applied to a copper cored titanium wire. The oxide coating is completely stable, and does not corrode, as is the case with traditional massive type anodes, such as silicon iron, graphite, or even platinum.
The stable anode element passes current to a highly conductive calcined petroleum coke backfill. The backfill is well compacted inside a galvanized steel canister. To allow moisture to quickly migrate to the coke backfill for increased electrical conductivity, the wire anode element is electrically connected to the steel canister - thereby accelerating the canister corrosion rate once the anode has been installed and energized.

Regardless of the type of impressed current anode used, proper ground bed design is paramount for optimum, low resistance performance. De Nora Corporation recommends the use of quality, conductive, carbonaceous backfill, a vent pipe, and centralizers, suitable cable, and good design practices and understanding.
