What Happens When Lightning Strikes
This is what happens when fence wire picks up the Electro Magnetic Pulse (EMP) from a close lightning strike. I do not think these fences actually got directly hit by lightning. Rather they might have picked up a stray bolt or more likely just the EMP.
Ben found these out in the field while he was repairing fencing after our recent nine time close call with lightning.
The top polywire has all the stainless steel strands intact.
The middle polywire has the wires burnt and frayed.
The bottom polywire has no wires left at all – they were vaporized.
Consider how much energy it takes to vaporize stainless steel… I’m glad we were not in contact with the fences at the time those bolts came a visiting.
This was all on the same fence. If you look very closely at the bottom polywire you can see tiny droplets of stainless steel embedded in the plastic. Miraculously the plastic look unburnt.
This is cheap, bargain basement 3 strand polywire. I do not recommend it. Buy at least six strands and preferably nine strands of stainless steel per polywire. This is not related to lightning but just good fencing. I bought this once because it was cheap and I was being chintzy. I would not repeat that. Cheap is as cheap does. Chirp, chirp.
