Busways, or bus ducts, are long busbars with protective covers. Rather than branching from the main supply at one location, they allow new circuits to branch off anywhere along the busway.

It can be used to shield the entire bus bar, or to separate different positive and negative conducting plates. The source of EMI is the fast current changes causing over-voltages and the resulting
