CATHODE CURRENT CONDUCTING ROD OF ALUMINUM REDUCTION CELL Russian patent published in 2018 - IPC C25C3/08 

FIELD: instrument engineering.

SUBSTANCE: invention relates to the cathode current conducting rod device for the aluminum reduction cell cathode device. Cathode current conducting rod contains metal substrate with internal cavity and insert, made of the high specific electrical conductivity material, installed in the internal cavity with possibility of electrical contact with the metal base. At that, the cathode current conducting rod is made of one or two or more rigidly fixed to each other metal bases, and insert is rigidly connected to the metal base by a connecting layer and is placed on one or more metal base side faces.

EFFECT: enabling possibility to reduce the voltage drop in the cathode section by increasing the cathode current conducting rod conductivity, with provision of acceptable electrical contact between the insert and the steel cathode rod throughout the reduction cell lifetime, significant alignment of horizontal currents along the cathode section length.
