In electric power distribution, a bus duct (also called busway) typically uses sheet metal, welded metal[1] or cast resin to contain and isolate copper or aluminium busbars for the purpose of conducting a substantial current of electricity. It is an alternative means of conducting electricity to power cables or cable bus.
