I found
this with a google search. I didn't read it so don't know if it will address your specific issue or not.
Yes the strand should be grounded at each end with #6 copper ground and a 10ft copper ground rod. I don't remember the intervals at which this was done, but I do remember bonding to the power ground, it may have just been where it was available. I really don't recall the B.S.P on this. I kind of recall at one point the practice changed to where we didn't bond to the power ground, but I'm not positive about that. I do remember having "hot" grounds a few times when the ground wire to the ground rod was broken on power poles. We were required to test the ground wire prior to climbing a joint use pole.
Here is my google search if it helps.
