Zhongfu Aluminum Company installed a short-circuit port splitting device independently developed on the column busbars at both ends of the electrolytic cell, which can effectively reduce the reactive pressure drop by 15%.

After the electrolyzer is shut down, there will be a large number of reactive pressure drop at the intersection, commonly known as "black voltage", which affects the power consumption of the electrolyzer. In order to reduce the “black voltage,” Zhongfu Aluminum has independently researched and developed the shunting technology and reduced the reactive pressure drop after repeated experiments.

Up to now, the company has used this technology on nearly 90 major repair slots. Test data shows that the single slot reactive voltage is effectively reduced by 15%.
