Application area

MMO titanium complete anodes are meant to be used as elements of shallow anode grounding for installation in soil with a high specific resistance.

Technical details

Complete groundbed Mendeleevets-MRKP / Mendeleevets- OPPK is a container with a MMO titanium electrode inside and the hollow space around it is filled with a coke-mineral activator (KMA).

Container is a case for even spreading of KMA and also for comfort transportation and installation. Container is made of galvanized steel and it dissolves fast after installation. There is a clamp at the top of the groundbed to facilitate installation work.

Length of a connecting cable in standard option is 2 m. Quantity of anode groundbeds, distance between them and the type of disposition are determined by the project of cathodic protection. Both types of disposition are possible: horizontal and vertical.

Joining of an anodic cable to the main cable is carried out by using thermit welding or cord fasteners. We use thermocontracting couplers for isolation of cable joinings.
