Busbar Processing Unit for Medium Voltage Switchgear

Product Specifications

Technical details and manufacturing context for Busbar Processing Unit

Definition

A Busbar Processing Unit is a critical component within the Medium Voltage Switchgear Assembly System responsible for the precise fabrication of copper or aluminum busbars. It performs essential operations such as cutting to length, punching holes for connections, and bending to required shapes, ensuring the busbars meet exact electrical and mechanical specifications for safe and reliable power distribution within the switchgear. The unit typically uses CNC (Computer Numerical Control) technology to automate processing steps. A feeding mechanism positions the raw busbar material. Hydraulic or servo-driven tools then execute programmed sequences for cutting (via shearing blades), punching (with dies and punches), and bending (using forming tools) to transform the material into finished busbar components ready for assembly. The unit is designed to process copper (Cu-ETP) and aluminum alloy (e.g., 6063-T5) busbars. Key parameters include a maximum busbar width of 120–160 mm, maximum thickness of 10–12 mm, punching force of 300–600 kN, bending force of 200–400 kN, punching diameter range of 4.5–30 mm, bending angle range of 0–90°, positioning accuracy of ±0.1 mm, and cutting length accuracy of ±0.2 mm. The unit operates with a supply voltage of 380–480 V AC (IEC 60038), control voltage of 24 V DC (IEC 61131-2), and is designed for an operating temperature range of -10 to 50°C (IEC 60721-3-3). It has a protection class of IP54 (IEC 60529) and a machine weight of 1500–3000 kg. Note that the listed operating pressure of 1.0–1.6 MPa is provided as a reference; All values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier.

Working Principle

The unit uses CNC technology to automate processing. A feeding mechanism positions the raw busbar material. Hydraulic or servo-driven tools execute programmed sequences for cutting (shearing blades), punching (dies and punches), and bending (forming tools). The process transforms copper or aluminum busbars into finished components ready for assembly.
