Overhead Cable Ampacity

Overhead Cable Ampacity

Overhead Cable Ampacity

(OP)
I would like to find an affordable, yet easy to use with WIN95, program to calculate the ampacity of various overhead conductors - AAAC, ACSR, etc. - for various temperatures and altitudes. Can anyone recommend such a program?
Thanks!

RE: Overhead Cable Ampacity

If you are looking for a program that is designed for bare overhead distribution conductors, there is a basic program included  with IEEE 738, but it is DOS based.  

I found one that requires you to have AutoCAD at: http://engineering.software-directory.com/software-2.cdprod1/002/070.Bare.Wire.Sizing.shtml
I guess it is a module that you use with AutoCAD.

There is one other program I found out there called ThermCap.  Their website is located at www.thermcap.com and it says it uses the IEEE 738 methodology.  This one looks to be a stand-alone program for windows operating systems.
Hope this helps...

RE: Overhead Cable Ampacity

Try WWW.Powerline.com they have software called PLS-CADD/LOADS that performs thermal ratings of OH line conductors.  Also the old Westinghouse T&D Manual goes through calculations using Schurig and Frick formulas to determine thermal rating of bare OH lines.
