Lida "ONE" MMO Tubular Anodes by De Nora Tech

Overview The De Nora LIDA® ONE anode is the newest in the family of mixed metal oxide anode products specifically tailored to the cathodic protection of buried structures. Designed for installations where a single anode on a string is preferred for groundbeds with widely varying soil resistivities, the mixed metal oxide coating is specially formulated for use in a carbonaceous backfill.   LIDA® ONE is a 1" diameter titanium tube with a precious mixed metal oxide (MMO) coating. This mixed metal oxide is a crystalline, electrically-conductive coating that activates the titanium and enables it to function as an anode. When applied on titanium, the coating has an extremely low consumption rate, measured in terms of milligrams per year. As a result of this low consumption rate, the tubular dimensions remain nearly constant during the design life of the anode, providing a consistently low resistance anode.   By increasing the length of our tubular anode, yet reducing total current output, De Nora has created another reliable mixed metal oxide anode product line with even greater cost savings over competitive anode technologies. As with all of De Nora's mixed metal oxide tubular anodes, the combination of a tough and lightweight product, its ease of handling and installation, the superior mechanical connection, and our five year, no hassle warranty, makes LIDA® ONE the ONE anode for unparalleled CP performance.                                                                              The "Single Anode" Concept from De Nora:  ONE anode, ONE cable. It's that simple!   Features    Designed to be used as a single anode; ONE anode on ONE cable. Durable - no breakage or damage while getting it to the job site. Mixed metal oxide (MMO) coating specially formulated for maximum performance in coke backfill. Special crimped moisture seal to prevent damage to electrical connection. No lead and no epoxy potting compounds needed. Five-Year Product Warranty.

Whether economics are your primary consideration, or a severe groundbed operating environment is anticipated, we provide LIDA® ONE with the cable that best meets your requirements. LIDA ONE anodes can be produced with an internal anode weight for assistance in loading deep well anode system.  If this is a desired option, please alert your Farwest representative of this need.     LIDA® ONE Cable Types Type WireSize Nominal OuterJacket Inner Jacket MaximumCurrentOutput Weight(kg/m) Length(lbs/ft) HMWPE #8 0.13 0.09 HMWPE None 27 #6 0.18 0.12 HMWPE None 50 ECTFE (Halar)/HMWPE #8 0.13 0.10 HMWPE ECTFE (Halar) 27 #6 0.18 0.12 HMWPE ECTFE (Halar) 50                                 Regardless of the type of anode used, proper groundbed design is paramount to optimum, low resistance performance. Farwest recommends the use of quality, conductive, carbonaceous backfill, a vent pipe, suitable cable, and proper design practices and technical understanding.
