Mendeleevets-MTKG – deep, complete magnetite anodes
Complete deep groundbeds Mendeleevets-MTKG are used as an element of deep anode grounding for installation in soil with high specific resistance. The groundbeds are installed into holes vertically.
- magnetite electrode;
- connecting cable;
- coke-mineral activator (CMA);
- gas outlet tube;
Groundbed Mendeleevets-MTKG is a container with a magnetite electrode inside and hollow space around it is filled with coke-mineral activator (KMA). The container is a case of the groundbed and it serves for convenient transportation and installation. This case dissolves during exploitation.
The groundbed is fixed by means of directing corbels. It gives the possibility to assemble the blocks of complete deep groundbeds into the chain that allows to raise current loading and to reduce transitional resistance. Max block quantity in a chain is 24 pieces.
Gas that is formed while working of deep groundbed is drawn outside to the surface through the gas outlet tube. The gas outlet tube has perforation along all the height of the chain and is delivered for the concrete order on the basis of one tube for one chain of groundbeds installed in a borehole.
The kind of deep ground, consisting of groundbeds Mendeleevets-MTKG ( quantity of blocks in a hole, quantity of boreholes, distance between boreholes, etc.) is determined by the project of cathodic protection.
As exploitation experience shows complete groundbeds have minimum time period of going out to operating modes and low value of resistance to current spreading. High degree of factory readiness noticeably simplifies the technology of anode groundbeds installation.
Each block has a connecting cable. The length of the cable is determined by the depth of the installation in a hole, that’s why the cable doesn’t have any discontinuities along the length and they are drawn outside to the surface to be attached to the anodic cable line.
|Current load, A, not more than||6,0|
|Anodic dissolution rate, kg/(A∙year), no more than||0,03|
|Dimensions of electrode working surface, mm:
- length (height)
|Assembled anode dimensions , mm, no more than:
- length (height),
|Anode weight, kg||5,4|
|Assembled anode weight, kg, no more than||50|
|Max quantity of groundbed blocks in the borehole, pieces, no more than||24|
|Service lifetime, years, no less than||35|
The delivery set depends on the main order parameters: quantity of blocks and the depth of the hole for the installation. All consumables needed for the groundbed installation and their connection to the anodic line are included in the delivery set.
