Abstract:

Cu-Al composite row was produced by continuous cast-rolling technique and metallurgical bonding interface was achieved. The microstructure of interface and the composite mechanism was investigated. Isolating switch was fabricated by using copper-aluminum composite row as current-carrying conductor. Main performance index and technical parameters were evaluated. The composite row shows excellent mechanical property and conductivity: overall tensile strength of 102MPa, elastic modulus of 1.5GPa, resistance rate of 0.0216Ωmm2/m and carrier density of 750A. The results present that the temperature rise, circuit resistance, mechanical life and other properties of the copper-aluminum composite row can meet the requirements of being the current-carrying conductor of isolating switch.
