6.7 SEMI-PERMANENT AND PERMANENT FENCES
Steel posts are the quickest and easiest way to set up a fence, but timber
and fibreglass posts can also be used. Make sure that the wires are tight
enough that there is no sagging. 2.5mm galvanized fence wire is recom-
mended as poly tape or rope will degrade and break over time. Safety
signs need to be fitted as per the requirements outlined in the “General
requirements for electric fences” part of this manual.
6.8 THE IMPORTANCE OF INSULATORS
If the live wire is not well insulated the fence load will be much higher,
this means for any given length of fence the voltage will be lower. Pieces
of wood and garden hose are not good insulators. Use the ones made for
the job and you will get a better result.
In a fence return system the earth wire(s) do not need to be insulated, in
fact if you are using steel intermediates the more times the earth wire
touches a metal post the better it is “earthed”.
UV stable poly insulators will last much longer than non-UV stable plas-
tics. Plastic insulators are not as susceptible to fracture as ceramic insula-
tors. However, ceramic insulators are better in grass fire prone areas as
they do not melt.
6.9 MAINTENANCE
On permanent fences maintaining the fence is important, especially dur-
ing the warmer months when plant growth is at its highest and after any
large weather events.
1. Check the fence voltage using an electric fence volt meter. The JVA
fault finder will also detect faults and direct you towards them.
2. Keep vegetation away from the fence. If it touches the fence it will
reduce its performance. Along permanent fence lines you may wish
to use a weed killer to deter any growth.
3. Check that nothing has fallen against the fence and that the wires are
not broken or have been unclipped from insulators.
The energiser battery must be checked. If the energiser is flashing a low
battery warning it is time to recharge or replace the battery
