At present, the electromagnetic launching weapon system is steadily turning to its engineering applications. Among them, the bus-bar, as a necessary link of the pulse power supply to transmit energy to the electromagnetic launcher, has high engineering requirements on its high power, miniaturization and lightweight. This paper analyzes and studies the high power, miniaturization, lightweight and other aspects of the bus-bar, puts forward a disk bus-bar, and compares it with other bus-bar,
