In the design of Safe-Fence Electric webbing several important issues were
considered. The composition of the plastic monofilament, the type of wire
to be used, the breaking strength needed to be effective, and the wire type
and size to be used for safe contact, long life and good conductivity. The
polymers used in Safe-Fence monofilament are the highest quality high density
polyethylene resins available, specifically formulated for radical temperature
conditions. The best ultra violet inhibitors are added to significantly
reduce deterioration from the sun even in desert areas.
Safe-Fence wide polytape contains 33 strands of 20 thousandths diameter
monofilament.
In our wire selection the most significant issue was longevity. As most
metal materials suffer a degenerating reaction when exposed to the elements
it was clear that stainless steel was the only choice to achieve an acceptable
life expectancy. The degeneration that occurs with other metals comes in
the form of rust, corrosion or oxidization, all of which reduces electrical
flow. The downside of stainless is that it has lessor conductive value than
aluminum or copper, however that value remains constant over a long period
of time where the others decline radically. Less conductivity is easily
overcome with larger wire and the right sized fencer.
The strength of the wire is also an important factor. We must keep in
mind that it is not a matter of if the horse hits the fence, but when the
horse hits the fence. When copper wire is forced it elongates and becomes
smaller thereby reducing electrical flow. On the other hand aluminum is
weak and not flexible and breaks very easily. Safe-Fence webbing has the
proper balance of size and number of stainless steel wires to offer the
strength and conductivity for what we believe to be the ideal horse fence.
Safe-Fence Electric System contains 15 strands of 12 thousandths diameter
- 304 stainless steel wire.
The material composition of Safe-Fence webbing offers strength comparable
or better than traditional fence materials, its extreme flexibility is enough
to withstand day to day activities, but it will tear in cases of extreme
impact and not cut the animal. |
