Stringing conductor
The reel trailer is grounded,the Wire is grounded with a Hubble rotating ground attached on the very end of the wire coming out of the wood reel that is bolted to the reel shaft.Then another ground is attached to the same rotating Hubble reel bearing that rotates on the reel shaft which is connected to the system neutral.We do not use mats,just rubber gloves and stay isolated from reel.The tensioner on the other end is grounded also,breaker one shot.When the wire reaches its destination its ground as we go till all are pulled in and grounded.Sagging is done on the least hazardous end.If its a long pull then we will ground again accordingly in the middle or just rubber glove tying the conductor in.
