Bus duct (also called busway) is a sheet metal duct or also cas resin insulated containing either 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.Originally a busway consisted of bare copper conductors support "ed on inorganic insulators, such as porcelain, mounted within a nonventilated steel housing”


* The phase bus bars are highly insulated from each other using heat shrinkable sleeves that offer high insulation.
* M. 5. Angle supports are provided for perfect fitting of the bus ducts.
* Electrolytic Copper metals are used as conduction metals for the bus bars.
