Need Data From Westinghouse Transmission and Distributiuon Reference
Need Data From Westinghouse Transmission and Distributiuon Reference
(OP)
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

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://ap
2) Alcan: http://www
Hope this helps.

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.

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