ANODE EARTH ELECTRODE Russian patent published in 2016 - IPC C23F13/06 

FIELD: electricity.

SUBSTANCE: anode earth electrode comprises a moulded electrode with a cross-shaped cross-section, having equally spaced projections, connected by arcs bent from the electrode centre, a current lead, a cable and a heat shrink sleeve in the form of a cap with a hole for sealing compound pouring. The electrode has two current leads located at the opposite ends of the electrode, and being contact assemblies containing the fused into the electrode inserts of a cylindrical shape with the diameter being 0.2-0.4 of the electrode diameter, the length being 0.1-0.15 of the electrode total length, made with grooves to the depth of 3-6 mm and width of 5-15 mm. The inserts are fused in the electrode by 2/3 of its length, and on the side surface of the inserts not poured by the electrode material platforms are made to secure cover strips being 0.60-0.65 of the insert diameter fixing pressing of the current lead cable in the form of a loop. The inserts are made out of an alloy having the coefficient of thermal expansion close to the coefficient of thermal expansion of the electrode material, and as the sealing compound the silicone polymer filler is used.

EFFECT: electrode design increases its mechanical strength and operation reliability during the electrodes assemblage to a string.
