Data centre power distribution
Rack densities have moved from 5β15 kW to 60 kW and beyond, and the busway feeding them has to be fabricated to match.
Rack power density has moved from a 5 to 15 kW baseline to 60 kW and beyond for AI-optimised racks, and overhead busway has largely displaced cable tray at those densities because it is denser and can be reconfigured. For a fabricator that shows up as three things: more joints per run, tighter joint-plane tolerance because the joints are carrying more current, and plating specifications that were once optional becoming standard. Joint ratings of 400 A and above continuous are now routinely specified. None of this changes the process; it raises the tolerance and the traceability the process has to hold.

Technical background
Punching
Punch-to-die clearance for copper and aluminium busbar
How to set punch-to-die clearance per side on 6-20 mm copper and aluminium bar, read the sheared edge, and specify burr height on the drawing.
Standards
Busbar hole patterns and what DIN 43673-1 actually specifies
What the four pages of DIN 43673-1 govern, the engineering behind edge distance, pitch and hole diameter, and why DIN 46433 is not a busbar standard.
Standards
Which busbar standard applies to your job
A decision tree from product type, voltage class and destination market to the governing standard set, with each standard placed at its actual scope boundary.
Cost and economics
Busbar nesting and scrap: building a cost model that survives audit
Yield arithmetic on 6000 mm copper bar, why remnant length distribution beats clever algorithms, and how to work the annual copper cost of scrap.
