Mendeleevets-MKG – deep, complete silicon iron anodes
Complete deep groundbeds Mendeleevets-MKG are used as elements of deep anode ground for installation in the soils with high specific resistance. Groundbeds are installed into boreholes in vertical position.
- silicon iron electrode;
- connecting cable;
- coke-mineral activator (CMA);
- groundbed case;
- gas outlet tube;
Complete groundbed Mendeleevets-MKG is a container with silicon iron electrode inside, and the hollow space around it is filled with a cokemineral activator (KMA). Container is a case for comfort 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 16 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 the concrete order on the basis of one tube for one chain of groundbeds installed in the borehole. The length of the gas outlet tube is equal to the depth of the borehole.
The kind of deep ground, consisting of groundbeds Mendeleevets-MKG (quantity of blocks in a borehole, 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 installation in the borehole, 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.
|Max current load, A, not more than||8,8|
|Anodic dissolution rate, kg/(A∙year), no more than||0,25|
|Dimensions of electrode working surface, mm:
- Length (height)
|Assembled anode dimensions , mm, no more than:
- length (height)
|Nominal anode weight, kg||43|
|Assembled anode weight, kg, no more than||75|
|Max quantity of groundbed blocks in the borehole, pieces, no more than||20|
|Service lifetime, years, no less than||35|
The delivery set depends on the main order parameters: quantity of blocks and the depth of the borehole for the installation. All consumables needed for the groundbed installation and their connection to the anodic line are included in the delivery set.
