Heavy-Duty Dense Busbar Trunking System 400–6300A 1000V AC

Quick AnswerHeavy-Duty Dense Busbar Trunking System ⁦400–6300⁩A 1000V AC — 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 run instead of a bank of cables — A single 1000 V trunk carries the current that would otherwise need several parallel cable sets and their derating study.
Aluminium-magnesium housing — The shell is lighter than steel and does not rust in a humid plant room, which matters when the run is 100 m overhead.
Sealed along the whole run — Dust and splashing water are kept out at the joints, which is what actually fails in real plant rooms, not the busbar itself.

⁦400–6300⁩ A dense busbar trunking rated 1000 V AC at 50/60 Hz.
Aluminium-magnesium housing, IP54 or IP66, pollution degree 3.
Serves as the main line above rack rows or along plant aisles.
Once a hall needs more than a few hundred amps, the head-end cabinet stops being the answer: cable bundles grow stiff and unmanageable, voltage drop eats into the margin, and every tap-off means another field termination. A dense busbar run carries the whole main line in one compact profile, with tap-offs wherever the load actually sits.
The run is built from three elements: a feed section from the transformer or main switchboard, straight trunk sections in standard 1 m, 2 m and 2.4 m lengths, and plug-in tap-off boxes. Elbows, offsets and custom lengths follow columns, expansion joints and building curves, so the line stays straight in plan and takes the shortest path through the room. Maximum horizontal support spacing is 2 m.
The housing is aluminium-magnesium alloy, a profile chosen for stiffness as much as for looks: it carries the copper without deformation and closes the enclosure to IP54, or IP66 where washdown and dust demand it. Conductors are T2 copper bars — aluminium is available where weight matters — laid in a distributed heat-dissipation structure, so heat leaves through the housing by air conduction instead of piling up at the joints. Connector bolts are torqued to 80 N·m ±5 N·m.
Rated insulation and operating voltage are both 1000 V AC, rated current spans 400 A to 6300 A, and short-time and peak withstand currents follow the current class selected. Installation category IV and pollution degree 3 suit the plant floor and the substation room alike. Copper or aluminium conductors, copper bars per phase and overall dimensions are all set by the current class.
Typical use: industrial plants replacing cable busways on long runs, data halls fed from a single main line, metro and tunnel projects, and substation low-voltage outgoing circuits. Every project is engineered to your single-line diagram — drawings in 30 minutes, a quotation within the hour, from a 12,000 m² plant working to ISO 9001 with CE and EMC certified components.

Frequently Asked Questions

What are the rated voltages and frequency of the run?

Rated insulation voltage and rated operating voltage are both 1000 V AC, at 50/60 Hz.

What material is the housing, and what protection level can it reach?

Aluminium-magnesium alloy, closed to IP54 as standard and to IP66 where washdown or dust requires it; installation category IV with pollution degree 3.

Copper or aluminium conductors — and how many bars per phase?

T2 copper bars are standard, with aluminium available where weight matters. Bars per phase, overall dimensions and weight all follow the selected current class between 400 A and 6300 A.

How far apart are the supports, and how are the joints tightened?

Maximum horizontal support spacing is 2 m, and connector bolts are torqued to 80 N·m ±5 N·m, so joint resistance stays stable over the life of the run.

How are Icw and Ipk fixed for a project?

Both follow the current class selected. Give us the fault level from your single-line diagram and the run, its tap-offs and the protection settings are matched to it.

What ambient conditions does the run accept, and how fast can it be engineered?

−5 °C to +40 °C with a 24-hour mean of 35 °C, which covers plant floors and substation rooms. Routes, supports and tap-off points are engineered from your single-line diagram — drawing in 30 minutes, quotation within the hour.
