Technical details
Groundbed Mendeleevets-MTKG / Mendeleevets- MPGK 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 / Mendeleevets- MPGK ( 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.
