How many volts on that primary? I've been told by linemen that clean ropes are safe for primaries. I personally had one get thrown clean over a primary once, and it never tingled me at all.
Scared me a lot, getting it down. I wish I had a picture of it. Dead, falling elm tree threw a branch backwards at least 60 feet after it smashed into the ground. Dragging the pull rope with it.
When it was all said and done, the rope was dangling from a clean span of primary wire, about 30 feet from the transformer serving a single farmhouse. And no linemen to call for about 30 miles.
