FIELD: electricity.
SUBSTANCE: anodic earthing device includes the carbonaceous conductor and the conductive shell, the conductor being represented by a carbon core. The conductive shell is represented by conductive concrete. The concrete contains the following components, wt %: sand 10-50, the colloidal graphite preparation 5-50, cement 5-50, the carbon filler 1-30.
EFFECT: increasing the operation period of an anode earthing device.
