Aluminum Vs Copper Bus Duct

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.

Aluminum vs copper 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. Aluminum bus bar conductivity is dependent on the alloy and temper. In cost comparisons between 3 200a copper versus 4 000a aluminium there is a saving of 23. Originally a busway consisted of bare copper conductors supported on inorganic.

In fact when comparing the two materials aluminum bus bar is twice as conductive as copper. Non segregated phase bus duct. Predominant aluminum bus bar material being utilized and is stronger than 1350 al because it has been hardened by heat treatment but it only has 56 the conductivity of copper. 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.

Bus bars or conductors conduct electricity. Eaton s comprehensive portfolio of busway solutions offers endless possibilities for meeting today s ever changing power requirements. Aluminum bus bar conductivity can be reduced depending on its alloying agents. This increases to 35 when comparing a 3 200a rating like for like in material.

Go to pow r flex busway. 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. Even going to a higher rated aluminium trunking over copper it still offers financial savings. Pure aluminum conductivity is approximately 65 0 of iacs international annealed copper standard.
