MMO Wire Anode for Distributed Current Output
Custom MMO coated titanium wire anodes engineered for reinforced concrete cathodic protection, tank bottom protection, embedded CP systems, pipeline corridors, and compact distributed current output applications.
Flexible Distributed Current Output for Embedded and Long-Area CP Systems
MMO wire anodes are selected when a flexible, compact, and distributed current output form is required. They are commonly reviewed for reinforced concrete cathodic protection, embedded CP systems, tank bottom protection, and project layouts where the anode must follow a defined route or spacing pattern.
Compared with larger anode forms, MMO coated titanium wire can be easier to route, embed, space, or install in restricted areas. The final design should be reviewed according to concrete or soil resistivity, chloride level, current output requirement, anode spacing, installation method, cable connection, and design life target.
Hele Titanium supports custom MMO wire anodes with project-specific wire diameter, coated length, coating loading, cable termination, packaging, labels, and documentation according to cathodic protection project requirements.
Flexible Linear Form
Suitable for routes, spacing layouts, and embedded applications where a compact anode form is required.
Distributed Current Output
Designed to spread protective current along the wire length instead of discharging from one concentrated point.
Custom Coated Length
Coated length and current output can be reviewed according to project layout and design life target.
Connection & Label Support
Cable connection, termination, labels, packing, and project documents can be supported when required.
What Is an MMO Wire Anode?
An MMO wire anode is a titanium wire substrate coated with mixed metal oxide. It is used as a compact linear anode for impressed current cathodic protection and other electrochemical systems where current must be distributed along a route, embedded area, or protected surface.
Because of its wire form, an MMO wire anode is often selected when installation flexibility, small diameter, custom coated length, and distributed current output are important. It can be used in concrete structures, under-tank systems, pipeline corridors, and other applications where larger anode forms may be difficult to install.

|---|---|---|
| Wire Form | A compact titanium wire coated with MMO. | Supports flexible routing, embedding, and space-limited installation. |
| MMO Coating | Mixed metal oxide coating applied to the titanium wire surface. | Provides electrochemical activity for impressed current output. |

Engineering Notes
- Current output should be reviewed together with coating type, electrolyte conductivity, operating environment, current density, and design life target.
- Soil and sand installations require review of resistivity, moisture level, burial depth, backfill condition, anode spacing, and cable route.
- Higher-conductivity environments such as brackish water and seawater generally allow higher current output than soil or freshwater environments.
- Final specifications should be confirmed according to project drawings, CP design criteria, installation method, monitoring plan, and documentation requirements.
