16×200 mm Hydraulic Busbar Processing Machine

16×200 mm hydraulic busbar processing machine with 500 kN force for cutting, punching and bending copper and aluminum busbars. Choose C or E configurations.

500 kN Cutting, Punching and Bending for Larger Copper & Aluminum Busbars

The TRANFOVIA 503 Series Hydraulic Busbar Processing Machine is designed for transformer and electrical equipment manufacturers whose busbar production exceeds the 12 × 160 mm capacity of the 303 Series and requires processing up to 16 × 200 mm.

With a nominal force of 500 kN and a punching range of Φ4.3–32 mm, the 503 Series integrates cutting, punching and bending in one multifunction machine platform. C-series and E-series configurations are available according to workstation organization, punching flexibility and bending-control requirements.

When 12×160 mm Busbar Capacity Is No Longer Enough

The main reason to move from the 303 Series to the 503 Series is processing capacity. If regular production exceeds the 12 × 160 mm range but remains within 16 × 200 mm, the 503 Series is the appropriate capacity class to evaluate.

  • Maximum busbar thickness is above the 303 Series range but within 16 mm.
  • Maximum busbar width is above 160 mm but within 200 mm.
  • Required punching diameter is within Φ4.3–32 mm.
  • Cutting, punching and bending need to remain integrated in one multifunction machine.

If regular busbars are wider than 200 mm or require the 16 × 260 mm class, the 803 Series should be evaluated instead.

Choose the 503 Configuration by Production Requirement

All main 503 configurations share the same 500 kN nominal force and 16 × 200 mm maximum busbar size. The model decision therefore depends on workstation organization, punching flexibility and bending-control requirements.

Configuration Three Stations Simultaneously Rotary Punching Digital Bending Control Recommended For
503C-1 No Standard punching No Basic 16 × 200 mm cutting, punching and bending
503C-3 Yes Standard punching No Simultaneous three-station production
503E-3 Yes Yes No Frequent punching and multi-process production
503E-3-S Yes Yes Yes Repeated bending with digital angle control

503C-1 vs. 503C-3: Capacity Is the Same, Workflow Is Different

503C-1 — Standard Sequential Processing

The 503C-1 is suitable when the factory needs the 16 × 200 mm capacity but does not require the cutting, punching and bending stations to operate simultaneously.

  • Suitable for moderate production volume and sequential job routing.
  • Appropriate when the larger 16 × 200 mmcapacity is required but advanced workstation coordination is not.
  • No digital bending angle control is listed.
  • Selected mainly for capacity rather than production-flow complexity.

503C-3 — Simultaneous Three-Station Processing

The 503C-3 keeps the same 500 kN force, 16 × 200 mm maximum busbar size and Φ4.3–32 mm punching range, but allows the three workstations to operate simultaneously.

  • Suitable when cutting, punching and bending workloads overlap during the same shift.
  • Useful where different operators need to work at separate stations at the same time.
  • Selected for workflow organization rather than larger busbar dimensions.

The upgrade from 503C-1 to 503C-3 is therefore a production-flow decision, not a capacity upgrade.

When Should You Move from 503C to 503E?

The 503E Series is intended for workshops that require 16 × 200 mm / 500 kN capacity together with rotary punching, a double-worktable arrangement and simultaneous three-station operation.

  • Different punching sizes or hole shapes are used regularly.
  • Multiple busbar designs are processed within the same production period.
  • The punching station benefits from a rotary die arrangement.
  • Cutting, punching and bending need to work independently at dedicated stations.

Rotary Punching for 200 mm-Class Busbars

For transformer factories processing many busbar designs, hole requirements can change between different profiles and diameters. The rotary punching arrangement on the 503E Series allows multiple punching dies to be prepared on the machine, reducing repeated die-changing interruptions when specifications vary.

  • Round holes
  • Elongated holes
  • Square holes
  • Different punching diameters within Φ4.3–32 mm

503E-3 vs. 503E-3-S: Standard or Digital Bending Control?

503E-3 — Standard Bending Configuration

Choose the 503E-3 when rotary punching, double worktables and simultaneous three-station operation are required, but digital bending angle control is not necessary.

503E-3-S — Digital Bending Angle Control

The 503E-3-S keeps the same 500 kN and 16 × 200 mm processing capacity while adding digital bending angle control. It is more suitable when the same bending angles or busbar geometries recur across production batches.

  • Repeated bending angles are used in production.
  • Operators need preset bending parameters.
  • Stored settings and error compensation are useful for repeat jobs.
  • The factory wants less dependence on manual angle judgement.

Busbar Cutting, Punching and Bending Capabilities

  • Cutting

The cutting station shears copper and aluminum busbars to the required length using a double-column shearing structure.

  • Punching

The punching station produces connection holes and other specified profiles. The listed punching range for the 503 Series is Φ4.3–32 mm.

  • Flat and Vertical Bending

The bending station supports flat and vertical forming for transformer busbar routing and connection geometry.

  • U-Bending and Additional Operations

With the corresponding tooling, the machine can also support U-bending, embossing, flattening, cable lug pressing and twisting.

303 vs. 503 vs. 803: Which Capacity Fits Your Busbars?

Series Nominal Force Maximum Busbar Size Punching Range Typical Selection
303 350 kN 12 × 160 mm Φ4.3–25 mm Standard transformer busbar sizes
503 500 kN 16 × 200 mm Φ4.3–32 mm Larger and thicker busbars
803 800 kN 16 × 260 mm Φ4.3–36 mm Wide heavy-duty busbars

If the largest production busbar already exceeds 12 × 160 mm, moving to a higher 303 configuration will not increase the basic size range. The 503 Series is the capacity upgrade for busbars up to 16 × 200 mm.

Applications in Transformer Manufacturing

The 503 Series is suitable for transformer factories processing copper and aluminum busbars that require a larger capacity than the 303 Series. Typical work includes preparing cut, punched and bent busbar connections for transformer terminals and other electrical connection points where the required dimensions remain within 16 × 200 mm.
