Characteristics Of Copper And Aluminum Bars

The power bus, as a key component in the circuit, is usually made of copper or aluminum, presenting a rectangular or chamfered rectangular section. Aluminum material is called aluminum busbar, while copper material is called copper busbar. They play an important role in conveying current and connecting electrical equipment in the circuit. Copper busbars dominate the high-voltage electrical field with excellent conductivity, while aluminum busbars are replaced in low current scenarios with cost advantages; Accurate ampacity calculation and selection guide provide key data support for electrical engineering.

▣ conductivity of copper bar
Copper has excellent conductivity, so copper bars are widely used in electrical equipment, especially in high-voltage electrical cabinets and low-voltage distribution cabinets. Copper bars are widely used in high-voltage electrical cabinets and low-voltage distribution cabinets because of their excellent conductivity, especially in occasions requiring high current transmission. The copper bars are usually marked with phase color letters or painted with phase color paint to distinguish different phases.

▣ cost advantage of aluminum row
Due to its cost advantage, aluminum materials are usually used under low current conditions. Although their conductivity is not as good as copper bars, the cost of aluminum bars is lower than copper bars. They are usually used under low current conditions, but their conductivity is not as good as copper bars.
