Well I find this particular bug both hilarious and annoying. Anytime a cow gets near one of my Iron Cables carrying 2024 EU, they start taking damage and making all kinds of noise. Now by near, I mean a good 6 blocks away or more.
It happens both on land and near insulated cables (contrary to the screenshot).
I however only take damage when I touch the cable.

That's weird, I didn't have zapped cows but instead got zapped from a 1x insulated hv cable coming from a MFSU going into a MVT at 1 block range.
2x stopped the zapping, I could even walk on the cable then. So if 1x already zaps me with 1 block range how comes your bare one zaps you only on touching?
Anyways that zapping can be useful, I guess it can make a nice floor for a mob grinder XD eats maybe less power than a tesla coil, just need to keep the wire not longer than needed.
The range for zapping is always (meant to be) 1 block radius. More insulation > higher resistance against zapping. Depending on the voltage you transfer, 1x insulated may isn't enough.
Can't explain the bug shown int he picture, though.
