| ELTECH LIDA®
tubular anodes are titanium tubes with a mixed metal oxide
coating. The mixed metal oxide is a crystalline,
electrically-conductive coating that activates the titanium
and enable is to function as an anode. The mixed metal
oxide anode has an extremely low consumption rate, measured
in terms of milligrams per ampere-year. As a result of this
low consumption rate, the tubular dimensions remain nearly
constant during the live of the anode - providing a
consistently low resistance anode.
Whether operating in soil, freshwater, mud or sea water,
ELTECH LIDA® mixed metal oxide coatings
demonstrate very high chemical stability - even in
environments with very low pH values. Unlike other impressed
current anodes, the ELTECH LIDA®
coatings are not affected by the generation of chlorine.

A LIDA® "anode
string" is comprised of electrical cable threaded through
one or more tubular anodes. Electrical connection between
the anode and cable is via a patented, mechanical crimping
process. The crimp connection is likewise utilized to seal
the anode around the cable at both ends. Since only a
single cable lead protrudes from the hole, the junction box
is eliminated when using a LIDA®
string - reducing the cost of materials and labor.
String assemblies are also available in a looped
configuration with two tails, or as multiple, staggered
strings for system redundancy and maximum current
distribution throughout the groundbed.
Like any impressed current anode, proper groundbed design
is paramount to optimum, low resistance performance. ELTECH
Systems Corporation recommends the use of quality,
conductive, carbonaceous backfill, a vent pipe and
Ventralizers, suitable cable, and good design practices and
understanding.
