Option 4 - Upgrading existing fences
- Low cost per ft.
- Quick. No need to buy or install new posts. Can be done in a few hours.
- Simple. Doesn't require a contractor.
- Needs no special tools.
- Energized strands can act as "feeder wires" for temporary cross fences.
The strands are supported by insulators that hold the strand 6"–8" away (offset) from the existing fence.
Offset energized wires also prevent sheep and goats from rubbing fences or attempting to put their heads through fences—which extends fence life and saves animals from injury or death (meaningful for those who have removed a sheep or goat whose head was entrapped by a woven wire fence).
As you can see in the photos, the existing fence is rusted and old. Energized strands can either be added to or replace existing wire strands. The result isn’t as pretty as a brand-new fence. But it does work.
And it’s far less costly than tearing out the old and replacing it with new
Cost is driven by the number and type of strands.
Points to consider
- Number of strands. Best to keep them as few as possible to allow animals to graze under them.
- Spacing of insulators. In the inset photo at right, attaching one every other post was all that was necessary.
Attach an insulator at both end posts and as many insulators as the situation requires to keep the energized strand the same distance away from the existing fence and the soil. Tension rope and MaxiShock hand-tight--and HT wire twice that. Use insulated cable buried underground to cross gateways. It's useful, but not essential, to install switches at end posts.

Electric fence is a pain barrier, not a physical barrier. A common mistake is not electrifying it. Animals may escape or become entangled (and may die). On a % basis, entanglement is very rare, but it can and does occur. If animals are scared or starved it will not keep them in. The first time you put the animals in the net, you should be available to watch them for a while. That way if one were to get into the fence and get caught, you can turn the power off and get them loose.
Warning! Due to risk of fire, do NOT use continuous output energizers with electric netting or electro-plastic conductors such as rope, twine or tape. Use only with a low or wide impedance intermittent pulse energizer. (Fi-Shock™ brand energizers which are sold as low impedance, continuous current output should NOT be used with electric netting.) All energizers sold on Premier’s website use an intermittent pulse and are suitable for use with electric netting.
Dry conditions and wintertime usage may reduce the effectiveness of electric fencing. Ice and heavy snow can flatten netting and thereby damage it.
Dry or frozen ground may cause post spikes to bend or break if inserted with force. Pilot holes may be needed. We recommend using drivable or single spike posts in hard soils. Double spike posts provide more stability when the ground is soft.
