Installing a Permanent Power Fence
TM
Tie-downs are anchors to hold the wire
down in hollows. For timber droppers, use
the Screw in Tie Down (G6150) and the
Screw in Tie Down Handle (G6151) to hold
the dropper down, see
Figure 4.20
.
Install the remaining line posts where
necessary. On flat or level ground use one
post up to every 20-30m (100 ft) and three
fibreglass droppers in between. On hilly
or uneven ground posts and droppers will
need to be closer together to maintain the
wire height.
Run out the remaining wires, tie them off
to the strain insulators and attach them to
all the posts and tie-downs.
For untrained sheep, goats and similar
animals the bottom wire should be approx.
150mm (6”) above the ground to prevent
them getting under the fence.

The Fibreglass Quick Clip (G8350) allows
free movement of the wire when straining,
see
Figure 4.21
.
Choosing posts and droppers
There are a number of options for posts
and droppers: wood posts, fibreglass or
steel posts.
Soft wood
round, half round or quarter
round posts provide the basis for a strong
permanent power fence. Gallagher offers
a range of insulators for attaching electric
fence wires to the posts. Our G673 W
claw insulator provides a strong permanent
attachment system with large shield and
long leakage paths. Alternatively the G687
pin lock insulator and G690 powerlock
products enable the wire to be temporarily
removed from the fence for rapid change
in paddock configuration, drain cleaning,
track grading etc. Insulators are also
available for specialist equine fencing
products including G669 for 40 mm tape
and G676 for equifence. Insulators can be
attached to the post using staples, screws
or flat head nails.
Posts can be installed by digging a
hole and then manually backfilling and
ramming the post tight, or by ramming the
post into the ground using a tractor- or
trailer-mounted post ramming machine
(preferable). Post spacing depends on
number of wires, wire type, and terrain,
and can vary between 4 meters (multi-
wire undulating ground) and 15 meters (2
high tensile wires across flat ground). Post
spacing can be extended if fibreglass or
wooden droppers are installed between
the posts.
Steel posts
provide a simple alternative
to soft wood posts. Steel posts have the
advantage of being able to be installed
using a sledge hammer or manual post
driver, reducing the need for expensive
post hole borers or tractor mounted
rammers. They can also be driven into
hard ground more easily, having a thin plan
area.
Gallagher manufactures quality double
pinlock insulators (G686) for attaching
electric wires to steel “Y” posts, as well
