IEEE std 998-2012 Lightning Shield Wire and Masts (Lightning Rod)

[palojai]

It's my first time designing for Substation lightning protection using IEEE std 998-2012 Guide for Direct Lightning Stroke Shielding of Substations. I am almost done with the design, and I would like to specify a catalog number for lightning shield wire and lighting masts (rods), but I do not know what conductor size it needs to be or what material it needs to be, IEEE std 998 uses words "shield wire" vaguely, they do not specify what shield wire really is?

For instance, usually for grounding design, the conductor is specified to be: 4/0 bare stranded copper, and the rod is and 5/8" x 10 ft copper clad.

thank you in advance!

To me the shield wire is the wire shielding the structure/ feeder from being struck. The wire doing the protection.
I'm sure if you look Cos. like Erico, grounding equipment, pole line, Manuf., the wire going by class ratings.
I've installed it never specified it. Remember nice soft turns, you don't want the it to fly off the wire.
