deep magnetite anodes
Certification:
Application area
Deep magnetite groundbeds may be used for installation both in closed holes and in open ones (in such places where there is a static level of ground waters). Besides, this type of groundbeds can be used at reconstruction of overaged deep anode groundbeds (DAG) made from steel pipes.
Installation of magnetite anode groundbeds into the hole is made manually and do not require any additional works.
Gain of magnetite anodes
- passing magnetite electrode;
- end magnetite electrode;
- cable
Technical details
There are two types of magnetite grounding: a chain and a garland.
The chain is five magnetite anodes joined by a connecting cable. The cable goes through the internal cavity of the magnetite electrode and has an electric contact with it. The anodes are at a certain distance from each other. The intercenter distance between the electrodes in a chain is 1,7 or 3,4 m. The general length of the chain is equal to the length of the installation in a hole. Quantity of anodes in a chain may vary from one to five and it is mentioned in the order.
The garland is several chains of anodes in one hole, they are disposed one over another with definite distance which is mentioned in a project. Most often the garland consists of several chains from one magnetite anode.
If magnetite groundbeds are installed into closed boreholes the coke-mineral activator (KMA) must be used to fulfill the hollow space around.
For open holes polymeric perforated pipes are used. The length of the installation in open holes is determined by a season minimal level of ground waters as the electrodes must be placed below the water level. Big advantage of installation in open holes is opportunity to carry out examination, repair and replacement of groundbeds in use.
In the construction of deep magnetite groundbeds a connecting cable is a carrying element of the construction and it is used in the installation of the groundbed into the hole. You can see the schemes of installation of the deep magnetite anodes Mendeleevets-MTG below.
