Need Data From Westinghouse Transmission and Distributiuon Reference

[Elmir]

Hi,

I do not own a copy of the old westinghouse transmission and distribution reference book. If someone would be kind enough to look up the following information and post it on here I would very much appreciate it.

I am looking for the following characteristics of #2/0 ACSR cable:

Outside Diameter
Geometric Mean Radius (GMR) @ 60 cycles feet
Resistance

These items can be found in chapter 3 of the book in table 2-A (Characteristics of Aluminum Cable Steel Reinforced)

Best Regards,

Elmir

This is from the new book republished and updated by ABB. You can contact them for one, it comes with both a hardcopy and a CD copy.

OD 0.447
GMR 0.00510
Resistance: there are several, all ohms/mile
Small currents, 25 deg C, 0.706
Current approx 75% capacity, 50 deg C, 0.895

Thank you very much wbd.

When having to perform a study, I prefer to take into consideration as much as possible data provided by manufacturers on their websites. It’s quicker, free of charge and it’s the most updated info one can get. I do not have anything against consulting ABB/Westinghouse T&D reference if you consider it as a better procedure.

Try these sources:
1) Southwire:

http://www.southwire.com/processChannel.do#1

and select your product (i.e.

http://appprod.southwire.com/ProductCatalog/XTEInterfaceServlet?contentKey=prodcatsheet16

)

2) Alcan:

Hope this helps.

Vic3fan,

This is good. Unfortunately those manufacturer data do not provide the GMR for 2/0 AWG cables.

The OD are identical and the other data are comparable.

What I traying to say, that even this is an old info still is valid today.

GMR depends on the particular geometry and physical properties of the cable material (and frequency). Tables in any handbook will be 'typical' values only.

You can calculate it yourself if you know enough details of the cable construction:
