CONDUCTORS 121
A solution.Connection Problems and Solutions
High conductivity (low ohms/ft or mile) enables the
pulse energy and voltage to remain high all the way to
the far end of the fence.
Poor conductivity does the opposite as you can see
in the graph on the left.
1. We installed two 1500 ft fences side by side.
2. One fence used a good conductor (IntelliTwine).
3. The other fence used ordinary polywire with only
stainless steel filaments.
4. We allowed grass to grow and contact the far 50%
(750 ft) of each fence.
5. We then measured available joules at the points
shown (same energizer for each).
Conclusion: One will allow animals through the
fence at the far end. The other won’t.
Why conductivity & resistance matter
Also refer to our conductor charts comparing
conductivity on pp. 120, 123.
IntelliTwine
Resistance is 50 ohms (Ω) per 1500 ft.
Why? Because it has
both stainless steel
and tinned copper filaments
.
Polywire
R
esistance is 65 times higher—3300 Ω per 1500 ft.
So its conductivity is much lower than IntelliTwine.
The
difference?
It has only stainless steel filaments in it.
Two simple, “no cost” solutions
Alligator clips can burn through rope and twine if the energizer is large and the drain via weeds is high. Twist MaxiShock (p. 123) around the rope/twine and attach the alligator clip to the combination. On netting—attach the PowerLink (p. 141) to the stainless steel connector at the end post of all nets.Insulated “Maxi” to
HTWire?
We prefer Insulated MaxiShock (p. 123) over
Insulated HT wire (p. 140).
To connect it: Carefully remove the insulation
with a sharp knife. (It’s not easy.)
Then double it
as shown, slide
into the clamp and
tighten the nut.
Problem
InsulatedWire to Rope
Rope fence connections
A potential problem. High
joule pulses may “burn” the
small metal filaments.
An electric fence pulse is less than
3/10,000 of a second. But for that
instant the energy flow can exceed
50 amperes.
That’s why good connections
(tight, firm, no rust, metal-to-metal
contact) are very important.
The best way? Place 4"-6" of bare wire next to the rope and secure it with a Rope Link as shown.Problem Solution
Attach the PowerLink
(p. 141) where a Rope
Link (p. 141) covers rope.
