OHGW - overhead ground wire on a tr

[cesarcesar]

OHGW - overhead ground wire on a transmission tower: want to ask if this GROUND conductor (which is installed at the highest position of the transmission tower) should be a BARE conductor or JACKETED conductor.... I thought : IN CASE OF LIGHTNING STRIKE, the bare conductor completes the circuit to GROUND. thank you.

 

[crshears]

You have reasoned it out correctly; jacketed would be a pointless waste of money and defeat the purpose of readily conducting lightning strikes to ground.

"As iron sharpens iron, so one person sharpens another." [Proverbs 27:17, NIV]

 

[cuky2000]

For lightning protection with shield wire utility use bare OHSW or OPGW (Optical Grownd

Wire)

 

[cranky108]

I thought the use of 5/8" steel was what is typically used?

We use Alumoweld-Aluminum-Clad-Steel-Overhead-Ground-Wire for overhead shield wires.
