For transformer and heavy switchgear busbar in Saudi Arabia the 803U-3-C is the LTMC 3-in-1 machine to specify, because it raises nominal force to 800 kN and the working envelope to 20 mm × 250 mm — roughly 67% thicker and 56% wider than the 303U-3-C class. The punching range extends to ф4.3–ф34 mm, which covers the larger terminal holes used on transformer and busduct work, and the three processing units share one frame so a single operator completes punching, shearing and bending without re-clamping. Published accuracy is ±1° bending with ±0.5° repeat, on a 3 × 5.5 kW drive and a 2100 kg machine. It suits transformer manufacturers, MV/LV switchgear plants and busway producers running heavier copper sections. Confirm the die set and section sizes against your purchase specification.
Product Description
This series of CNC busbar processing machine has three processing units: punching, shearing/cutting and bending. The three unit can be used simultaneously or sequentially, which shortens the processing time and improves production efficiency. The bending unit adopts Siemens PLC of Germany.

Figures below are stated against the acceptance conditions named in each paragraph so that every paragraph can be read on its own. Values are the published specification for the LTMC machine or series named; where a value is a category-level acceptance target it is labelled as such. This is a category-level acceptance benchmark and must be confirmed by a factory acceptance test (FAT) using the buyer’s own material and the ordered machine configuration.
Test conditions: 800 kN nominal force applied to copper busbar at the top of the rated section. Specified value: 800 kN with 20 mm maximum thickness, 250 mm maximum width and a ф4.3–ф34 mm punching range. Comparison baseline: the LTMC 303U-3-C at 300 kN / 12 mm × 150 mm and the 503U-3-C at 500 kN / 16 mm × 200 mm — the 803U-3-C adds about 167% force over the 303U-3-C class and 60% over the 503U-3-C class.
Test conditions: repeated horizontal bends at the upper end of the 20 mm thickness rating. Specified value: ±1° bending accuracy with ±0.5° repeat bending accuracy, and a 12 × 120 mm maximum vertical bending size. Comparison baseline: the 303U-3-C class, published with the same ±1° / ±0.5° accuracy but limited to a 10 × 100 mm vertical bending size, so the 803U-3-C holds that accuracy on a larger vertical bend.
Test conditions: punching transformer terminal holes in the ф25–ф34 mm range on 20 mm copper. Specified value: punching diameter range ф4.3–ф34 mm at 800 kN nominal force. Comparison baseline: the 503U-3-C class, where the range stops at ф30 mm — about 13% smaller in maximum hole diameter.
