Mendeleevets-MK – shallow, complete silicon iron anodes

«Менделеевец»—МК

Included in the Gazprom register
Included in the Transneft register

Certification: CU (Customs Union),
GAZPROMCERT, GAZCERT

Favourable decision of a sanitary-hygienic
commission of experts

Application area

Complete anode groundbeds are meant to be used as an element of a shallow anode groundbed for installation in soils with high resistivity.

It is possible both types of disposition: horizontal and vertical.

Technical details

Схема Менделеевец-МК
  1. silicon iron electrode;
  2. coke-mineral activator (KMA);
  3. connecting cable;
  4. container;
  5. cover for tranportation;
  6. centralizer;
  7. clamp

Complete groundbed Mendeleevets-MK is a container with silicon iron electrode inside and the hollow space around it is filled with a cokemineral activator (KMA).

There are two modifications of the groundbeds different in weight and dimensions: MK(23) and MK(43).

Container is a capacity 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 the connecting cable is 2m in the standard option.

Quantity of anode groundbeds, distance between them and the type of disposition are determined by the project of cathodic protection.

Joining of anodic cable and backbone cable is carried out by using thermit welding or cord fasteners. We use thermocontracting couplers for isolation of cable joinings.
