     You might consider doing what the electric utilities do when they're 
working around live wires: sleeve them with rubber.  You might see this where a 
new power line is being installed above a live circuit that it's crossing, or 
where construction equipment like cranes might come into contact with the 
energized conductors.

     I would suggest slitting lengths of rubber garden hose and slipping them 
over the DE-ENERGIZED span or spans of electric fence wire below your dipole.  
I have no idea what the dielectric breakdown strength of rubber garden hose is 
but it's got to be better than having the dipole and fence wires in direct 

     Of course, I realize you will lose a span or two of electric fence 
<dissuasion> where you install the hose.  You'll have to decide whether your 
cattle or other animals are conditioned thoroughly enough to avoid the fence in 
those areas.
