The 303U-3-C is a versatile 3-in-1 busbar processing machine that combines CNC punching, cutting, and bending functions. Ideal for processing copper busbars with a force of 300KN, it is widely used in switchgear and transformer manufacturing. This hydraulic busbar machine offers high precision and efficiency for electrical component production.
Conclusion: 303U-3-C is a CNC busbar processing machine (maximum working envelope 12 × 150 mm; rated force 300 kN). The machine processes copper and aluminium busbars for switchgear, transformers and power distribution systems. It suits switchgear workshops, electrical equipment plants and busbar assembly lines that need repeatable output.
Condition: processing copper and aluminium busbars on the 303U-3-C. Value: Maximum thickness 12, maximum width 150. Baseline: against the smaller size class in the same series, which sets the material limit the 303U-3-C can handle.
Condition: punching or bending at full stroke on the 303U-3-C. Value: Rated force 300 kN. Baseline: the rated force is the reference and the die set and stroke are sized to hold it across the cycle.
Condition: punching busbar holes to switchgear drawings on the 303U-3-C. Value: Punching diameter ф4.3～ф25 Baseline: compared with single-die punching, a multi-station cluster completes several hole sizes in one clamping.
Condition: installing the 303U-3-C in a production workshop. Value: Machine size 1720×1220×1220 mm, weight 1220 kg. Baseline: against the larger model in the same series, this size drives floor space and shipping plan.
Product Description
copper busbar bending machine 303U-3-C
This series of busbar processing machine has three processing units: punching, shearing/cutting and bending. The three units can be used simultaneously or sequentially, the working stroke of each processing unit can be easily adjusted, which shortens the processing time and improves production efficiency. The main function is processing copper and aluminum busbar.
