Busbar Length x Busbar Size x 0.009
ex- Length= 12meter
Size = 60 X 10 mm
ie, 12 x 60 x 10 x 0.009
Ans = 65 kg
Can you please let us know what is "0.009" for???
Ans: 0.009 = copper density
Max. Current for 60 x 10mm = 60 x 10 x 1.55 = 930 AMP
What is "1.55" for??

∙ 9y ago2 to 4 Amps per square mm and for aluminium it is taken as 1 to 2 amps per sq mm depending on the maximum load that will determine the bus bar.

∙ 10y agohow can i calculate copper cable to bus bar size
e.g:
300mm2 cu/pvc/pvc cable, change in to bus bar size
Wiki User
∙ 11y agoyou have to start with the size. if it is more than 4" you have the go to the bus stop. than you pay them and eat spaghettio's. if this dosn't work, well your screwed.

What is current density of copper busbar for 4000A?
The current density for a copper busbar will vary as the size of the bar. And no, that's not a trick answer. More information about the application is needed to determine what size the busbar is, since only the ampacity was cited here. There are different specifications (sizes) for busbars, as you know. The deal is that there is usually a "temperature rise" factor that delimits what you're supposed to use. Higher temps mandate bigger bars, which you probably already figured out. The basic busbar size is set on how much heat the busbar will generate when conducting it maximun rated current. But factors regarding the thermal environment in which the unit is operating must be considered. Minimum size for 4000A is probably 1/4 x 10, but some applications will require up to 3/4 x 10 with some allowing something in between. With a specified size bar, you can easily calculate the current density by dividing the current (4000A) by the cross-sectional area. Pick one and go for it.
What a bus bar?
The term, 'bus', in 'busbar', comes from the word, 'omnibus', meaning 'to serve all'. A busbar, then, is a copper bar that connects several independent circuits together. For example, a generator might be connected to a busbar, serving several circuits all connected to that same busbar. There are separate busbars for line, neutral, and earthing (grounding) connections.
How do you calculate the amps rating of copper bus bars?
A formula for 60 Hz with reasonable ventilation: Imax = 7.73 x A^0.5 x p^0.39 A is the cross-section area in sq. mm and p is the circumference of the busbar's cross-section in mm. So for a busbar of 100 mm x 5 mm the maximum current is 1391 amps.

What is bus bar and how it is connected to the genarator?
The term, 'bus', is derived from the word, 'omnibus', meaning to 'serve all', and that's exactly what a busbar does.A busbar is a length of conductor which offers a common point of connection for several circuits. For three-phase systems, one busbar is required for each of the three lines and (where necessary) for any neutral. A separate busbar is used to interconnect the various earth (ground) connections.In the case of a power station, one or more generators can be connected to the same busbar system, as are the various transformers supplying the circuits leaving the power station. Normally, each input/output circuit is connected to the busbar system, not directly, but through circuit breakers and isolators.
