if the electric fence is overloaded (lots of zombies) whilst passing the cable thru a wall(totally bricking it up for protection)
It seems possible to get a reset on the endpoint of the wire to 0,0 co-ords.
and you can get an electric fence way past the end point of the normal wire.
It's happened a couple of times, but since it seems dependent on the number of zombies, it can be difficult to reproduce the conditions.
One interesting point.. if you get to the end of the wire, it suddenly snaps back to the correct position.
Also it appears to be fully working for killing whilst in the extended state.
