Spraying type laminated copper bar and preparation process thereof

The invention belongs to the technical field of copper bars, and relates to a spraying type laminated copper bar and a preparation process thereof. The preparation process comprises the following steps: preparing a plurality of copper bars with the same shape and different terminal lengths according to different structures of application occasions and connection requirements of terminals; performing epoxy powder high-temperature spraying covering treatment on the output surfaces of the copper bars; and performing overlapping bonding on the copper bars subjected to the powder spraying treatmentto form the laminated copper bar. Through the design of the laminated structure, the laminated copper bar is high in carrying capacity compared with cable connection, and is simple in layout; compared with sequential arrangement of the copper bars, the connection reliability is high, the insulating and cooling performance is good, and the occupied space is greatly reduced; for an application occasion of alternating curre
