Aluminum Vs Copper Bus Duct

In cost comparisons between 3 200a copper versus 4 000a aluminium there is a saving of 23.

Aluminum vs copper bus duct.

This increases to 35 when comparing a 3 200a rating like for like in material. In fact when comparing the two materials aluminum bus bar is twice as conductive as copper. Eaton s comprehensive portfolio of busway solutions offers endless possibilities for meeting today s ever changing power requirements. Go to pow r way iii busway.

Even going to a higher rated aluminium trunking over copper it still offers financial savings. 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. Non segregated phase bus duct. 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.

Pure aluminum conductivity is approximately 65 0 of iacs international annealed copper standard. It is an alternative means of conducting electricity to power cables or cable bus. 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. Aluminum bus bar conductivity can be reduced depending on its alloying agents.

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. 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. It separates the conductors from each other to prevent electrical faults.
