FIELD: electrolytic production of aluminum; design of bridging of cathode busbars of electrolyzer. SUBSTANCE: to reduce difference of values of transverse component of magnetic field in various zones of cathode, the length of of section of bridging of cathode busbars from nonferromagnetic plates from the left side of cathode shell is made larger than the length of nonmagnetic section located from the right side of cathode. EFFECT: stabilized process conditions of electrolyzer operation, reduced losses of cathode metal and increased current efficiency. 1 dwg
