It is an alternative means of conducting electricity to power cables or cable bus.
Aluminum vs copper 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.
This increases to 35 when comparing a 3 200a rating like for like in material.

Non segregated phase bus duct.
Even going to a higher rated aluminium trunking over copper it still offers financial savings.
Eaton s comprehensive portfolio of busway solutions offers endless possibilities for meeting today s ever changing power requirements.
Pure aluminum conductivity is approximately 65 0 of iacs international annealed copper standard.
Aluminum bus bar conductivity can be reduced depending on its alloying agents.
Originally a busway consisted of bare copper conductors supported on inorganic.
Bus bars or conductors conduct electricity.
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.
It separates the conductors from each other to prevent electrical faults.
Aluminum bus bar conductivity is dependent on the alloy and temper.
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.

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