What is a busbar system?
A busbar system, also called a busway or busbar trunking, distributes low-voltage power through enclosed copper or aluminium bars instead of large cables. It is used in high-rise buildings, factories and data centres, where plug-in tap-off boxes allow loads to be connected along the run.
What buyers compare
- Rated current and conductor material (copper or aluminium)
- Sandwich or air-insulated construction
- IP rating and fire resistance
- Tap-off box options
- Standard: IEC 61439-6
