MMO Tubular Anode
MMO tubular anodes can be used directly in fresh water or seawater environments. For large offshore steel structure cathodic protection, they can be assembled into remote ground anodes with simple installation and wide protection range. In soil conditions, pre packaged MMO tubular anodes form shallow buried or deep well anode ground beds.
Pre packaged MMO Anode: Outer MMO tubular anode fitted with solid copper terminal for good conductivity, connected with special YJV or PVDF/HMWPE cables. Filled with coke particles for maximum surface current output and sealed by epoxy resin. Multiple units can be connected in series or parallel to build complete pre packaged anode groups.
