This paper deals with the electric and thermal characteristics of the composite busbar composed of aluminum and copper. When AC current is flowing in Cu busbar used widely in conservative equipments like power cable, transformer, and switchgear & controlgear most current is concentrated on the surface of the busbar by the skin effect. Therefore, if the Cu region in the busbar having low current density is replaced with aluminum, we can largely reduce the product cost and weight of the busbar. To conform the performance of the composite busbar, we designed and fabricated a test Al/Cu composite busbar. Maximun temperature rise of the busbar was $35^{\circ}C$ when 1600 Arms of AC current was applied to the test composite busbar($120mm{\times}10mm$). Based on test results, we can expect to make the low-priced and light power equipments using the Al/Cu composite busbar.

Since the dissimilar bonded interface usually consists of intermetallic compounds (IMCs) layer and cracks, their mechanical and electrical properties can be influenced by microstructure at interface between two different metals. In this study, the friction welded Cu-Al busbar, which is widely used to connect a secondary battery and their component, is selected to analyze the influence of interfacial characteristic on their tensile strength and electric conductivity. Then, the electrical characteristics of Cu busbar and Cu-Al busbar were investigated by thermal flow analysis and temperature rise test. In addition, the relationship between the maximum saturation temperature and the electrical conductivity were discussed in terms of interfacial characteristics of the friction welded Cu-Al busbar.
