The 530kA potline has been put into industrial running in Xinjiang province, China. The potine includes 320 aluminum reduction cells and eighty cells are in production. It is the highest current potline in the world at present. A lot of new technologies were applied in the potline. Magnetic field was optimized, thus negative effect of vertical magnetic field was weakened and current distribution in cathodes was improved. Busbar allocation and installation was optimized, especially short-circuit busbar and upright-column busbar. High conductivity steel was used as cathode rods and three steel rods were installed in each cathode. Insulated layer was coated on each cathode steel rod near the cell sidewall. The potline has got low cell voltage and low anode effect frequency. Its cell voltage is about 3.90V and anode effect frequency is lower than 0.05 times per cell day. Further optimization and improvement need to be performed to get better performances.
