MMO Ribbon& Ti Conductor Bar
MMO ribbon and mesh are highly conductive anodes with a low consumption rate and life expectancy can be expected to exceed 50 years based on a 3A/M2 current density.
DOWNLOAD DATASHEET

MMO Ribbon consists of a solid ribbon of titanium substrate to ASTM 265 Gr 1 coated with precious mixed metal oxides (IrO2 /Ta2O5). All MMO anodes benefit from being pre-oxidized in a controlled environment prior to field installation meaning they are not reliant on protective film formation when installed and operational. MMO coating is highly conductive and the anodes have a very low consumption rate. This combination of characteristics results in a long-life expectancy even when the anode is subjected to a high current density rating. For example, MMO Ribbon life can exceed 50 yrs. with a 3A/m2 Current Density.

WHY USE MMO RIBBON?
MMO ribbon is often spot welded to titanium conductor bar forming a grid arrangement. The Ti conductor bar is used to distribute the CP current throughout the system under tank bottoms, providing a system with an even distribution of current.

MMO ribbon is suitable for both new and old structures, as well as steel reinforced concrete structures. MMO ribbon is also used for cathodic protection applications where there is a high current demand and limited space.

Ribbon is suitable to be directly buried into fine sand without any need for carbon backfill.

Power feed connectors (a 12.7 x 0.9 x 100mm strip of titanium conductor bar spot welded to a length of titanium wire to which a power source can be connected using a splice kit) are commonly supplied with ribbon and Ti conductor bar.
