aluminium bus bar current carrying capacity

You have posted the same query in many number of ways.

I have requested you to reply the application but you have not responded.

However i give some relavant details.

Since the current is very high ,it would be advisable for you to go in for Busduct with Aluminum Enclosure and Aluminium Busbar.

Aluminum Bus bars are to be in Flat form.You should have 4 runs of 200 x 12 mm Aluminum Flats per phase.

For 13 met length voltage drop will be very nominal within 2.0 %

I m thankful to u...for ur's reply.

I m satisfied with the data given by u. But sir, I m more consern with the method of calculation. plz let me know. and how u find the voltage drop will be only 2.0% for 13 meter.

and I m asking for apology to not replied last.

This is only basics of Electrical engineering.-Ohms law.

Voltage drop= Cureent X Impedance.

(Vd=I x Z)

Current is known to you.

Z- Impedance -Based on material,configuration,cross section etc.

Calculate Z per meter then arrive at for 13 metres.

You have to do the homework please.

Can u tell me the impact of length on Current carrying & Voltage drop in Bus Ducts. Usually for cable we mention about voltage drop but for Busduct no such restrictions are said. y So.

My point of view 4 runs of 200X10mm Al conductor is enough
