Both investment economics and technical requirements must be considered simultaneously. Generally speaking, the total cross-sectional area of the copper bars must meet the requirements for the maximum current, result in low heat generation, and keep the investment at an acceptable level. The cross-sectional area of the copper bar can be calculated at 1–2 A/mm2; however, taking into account the effects of high-frequency resonance currents such as ripples, a value of 1–1.5 A/mm2 is generally chosen. As for width and thickness, they are determined based on the dimensions of the device being connected. The contact area for copper bar connections should be calculated at 0.1~0.2 A/mm2. In ion-exchange membrane cells, since the current level is not very high, two copper bars are generally used as the DC busbars; using a single bar is not only difficult to process but also presents challenges during on-site installation. Diaphragm cells require a slightly larger number of copper bars, after all, the current is relatively high.
