Aluminum Vs Copper Bus Duct

Aluminum bus bar conductivity is dependent on the alloy and temper.

Aluminum vs copper bus duct.

Aluminum bus bar conductivity can be reduced depending on its alloying agents. Originally a busway consisted of bare copper conductors supported on inorganic. Pure aluminum conductivity is approximately 65 0 of iacs international annealed copper standard. Even going to a higher rated aluminium trunking over copper it still offers financial savings.

It is an alternative means of conducting electricity to power cables or cable bus. In fact when comparing the two materials aluminum bus bar is twice as conductive as copper. Non segregated phase bus duct. In electric power distribution a bus duct also called busway is a sheet metal duct or also cast resin insulated containing either copper or aluminium busbars for the purpose of conducting a substantial current of electricity.

Eaton s comprehensive portfolio of busway solutions offers endless possibilities for meeting today s ever changing power requirements. In cost comparisons between 3 200a copper versus 4 000a aluminium there is a saving of 23. It separates the conductors from each other to prevent electrical faults. This increases to 35 when comparing a 3 200a rating like for like in material.

They are made from aluminum or copper and vary in size housing an aluminum or steel enclosure to contain the busbars insulating system made of a combination of air epoxy and mylar. Bus duct comparison of the two technologies bus duct is defined in the nec 368 2 as a grounded metal enclosure containing factory mounted bare or insulated conductors which are usually copper or aluminum bars rods or tubes. Go to pow r flex busway. Aluminium is more cheaper than copper and in case of bus bar there is no compulsion of space so we can also use more flatter or comparatively bigger bus bar rather than using a copper smaller and less flattered bus bar.
