Dense Busbar Trunking System 100–800A AC/DC with Plug-in Tap-off Units

Quick AnswerDense Busbar Trunking System ⁦100–800⁩A AC/DC with Plug-in Tap-off Units — an IDCPDU Busway for data-centre backbone power distribution.

Tap-off boxes on a live busway — Add, move or remove a plug-in box while the duct is energised — a new row goes in without a shutdown window.
One busbar for AC and DC — The same run carries AC or DC tap-offs, so a lab bench and an AI hall share one product family — no second design, no second spare-parts list.
Standard 1 / 2 / 3 m sections — Runs follow column grids, corridors and building curves with stock lengths — no bespoke duct, no waiting on a special extrusion.
Tap-off units across current classes — One duct serves an instrument circuit and a heavy rack row on the same plug-in interface, so the spare-parts stock stays small.

⁦100–800⁩ A AC / ⁦400–800⁩ A DC overhead busbar for rack rows.
Three parts: incoming box, busbar trunk, plug-in tap-off units.
Tap-off units stay pluggable while the trunk is energised.
Row power in most halls still means a distribution cabinet at the head of each row and cable trays under the floor. Every new row brings another cable run, another set of breakers and a shutdown window — while the floor plan keeps changing. A dense busbar run replaces that whole chain with one line above the racks.
The system has four elements: an incoming box with main MCCB, surge protection and metering; a dense busbar trunk with T2 copper conductors in a compact profile; plug-in tap-off boxes; and standard trunk sections of 1 m, 2 m and 2.4 m, plus custom lengths and elbows that follow columns, aisles and building curves. Tap-off box and trunk form one unit, so the assembly sits close to the rack and takes far less space than row-end cabinet feeding.
Conductors are T2 copper bars in a distributed heat-dissipation structure: heat leaves through the housing by air conduction instead of building up at the joints. Temperature rise stays low under continuous full load, which keeps the run stable over years of operation.
One family covers ⁦100–800⁩ A AC and ⁦400–800⁩ A DC. Tap-off boxes come in 16 A, 32 A and 63 A, single or three phase, with one to three outlets, in angled plug-in, straight plug-in or bottom cable exit versions — standard, metered, or with phase selection. Typical use: data centres, telecom rooms, hospitals, laboratories and production lines where the layout changes but the power cannot be switched off.
Every project is built to your single-line diagram: drawings in 30 minutes, a quotation within the hour, from a 12,000 m² plant running ISO 9001 with CE and EMC certified components.

Frequently Asked Questions

What does an overhead busbar run replace in a rack row?

It replaces the row-end distribution cabinet, the underfloor cable tray and the field terminations behind them. A new row is then powered by plugging in a tap-off box instead of pulling another cable run.

Which tap-off box versions can be ordered?

16 A, 32 A or 63 A, single or three phase, with one to three outlets, in angled plug-in, straight plug-in or bottom cable exit versions — standard, metered, or with phase selection.

Why do the trunk dimensions change with the current rating?

⁦100–400⁩ A runs use a 180×156 mm profile, ⁦630–800⁩ A a 196×162 mm profile, and DC ⁦400–800⁩ A the 180×156 mm profile. The profile follows the current class, so a low-current row stays compact.

What conductor and cooling design is used in the trunk?

T2 copper bars in a distributed heat-dissipation structure: heat leaves through the housing by air conduction instead of collecting at the joints, which keeps temperature rise low under continuous full load.

What does the incoming box contain, and how much space does it need?

Main MCCB, surge protection and metering to project requirement, in 850×430×223, 1050×450×300 or 1100×450×300 mm; it covers ⁦100–630⁩ A AC or ⁦400–800⁩ A DC.

Can a run be fitted into an existing hall with non-standard lengths?

Yes. Straight sections are 1 m, 2 m and 2.4 m, and custom lengths and elbows are built to your single-line diagram; the final configuration is fixed together with our engineers before production.
