People who work in specific industries sometimes seem to think that everyone knows what their acronyms mean, but they don't.

What's ISP/NSPB/SPB mean?

I guess ISP=Isolated phase Bus duct

NSPB=Non Segregated Phase Busduct

SPB=Segregated Phase Busduct

but the guest who posted the query should explain.

You are right, they are carring-current conductors.

Just like NSPB:

Enclosure(Al.) size:1000mm*500mm

Conductor(Al. 1035) size: 2-100mm*10mm(per phase, total 3 phases)

Current:2000A

ambient temperature:40 Celsius

Calculation:

a: the conductor's temperature and losses?

b: the enclosure's temperature and losses?

These are design parameters.One should have knowlege, expertise and time to prepare.

Generally Designers will do these calculations for specific projects.

We can do it for you but on chargable basis.

I'm studing the calculations for all kinds of conductor's shape, could you please provide some data/information to me? Thanks.
