Description
The self-supporting sections are made of aluminium or, if needed, of copper, and the flat busbars have extruded insulation of black halogen-free plastic. The design is divided by phases, the joints are enclosed phase by phase, and fire-resistant partitions stand between rooms, so an arc between phases cannot occur. The PE bar is connected to all metal parts. Turns in the horizontal and vertical planes are made by bending, which reduces the number of joints, and straight sections longer than 20 m get thermal expansion compensators. Thermographic windows are placed at the bottom of the enclosures, so the heating of joints is checked with a thermal imager without dismantling. The busbar trunking is connected to switchgear from above, below or from outside, and also to substations; current transformers can be placed next to the substation. Routes are designed from 3D models, the system is divided into sections convenient for transport, and after the end of its service life it is easy to recycle. VEBA busbar trunking has been supplied, among others, to the oil refinery in Porvoo.
How to choose
The upper current limit is set by the busbar material: aluminium versions go for 1000–4500 A, copper ones for 1000–5500 A, so above 4500 A only copper remains. The width is constant, 585 mm, and the height depends on the number of layers and is 101, 175 or 245 mm for 1–3 layers. The weight of aluminium trunking is 15–70 kg/m, of copper trunking 40–125 kg/m (at 35 °C and IP31); it determines the pitch and load capacity of the supports. If you need the LV switchboard itself or a motor control centre up to 5000 A, look at the VEDA MCC.

FAQ
What is the peak current of the VEBA busbar trunking?
The website states 176 kA, the brochure 264 kA, at a short-time withstand current of 120 kA for 1 s. For a project, the values are checked against the data sheet of the specific route.
What protection degree does the VEBA busbar trunking have?
From IP20 to IP54, the standard version is IP31, the sealed one IP54. For damp and dusty workshops the sealed version is taken.
How does the VEBA busbar trunking pass through walls and floors?
Fire-resistant penetrations of classes EI-60 and EI-120 exist for this. With separation made according to the instructions, the construction is arc-resistant up to 30 MW.
Which standards does the VEBA busbar trunking comply with?
IEC 61439-1 and IEC 61439-2. The busbar trunking is certified by SGS Fimko, and the CE and FI marks are on the rating plate.
