When making permanent connections in electrical
fences, make sure that the joins make good
electrical connections. One loose connection can
equal a resistance of 500 ohms, and a few loose
connections can cause a significant voltage drop.
Use good-quality crimp sleeves, crimped with
the proper crimping tool, to make electrical connections.
A round, hard material such as high-tensile
wire does not make a good electrical connection
when wrapped back around itself. Therefore, avoid
knots and wraps unless the person constructing
the system has the ability to make tight wraps.
Too many graziers depend upon their energizers
being able to punch their way through loose wraps
instead of taking a little more time to do it right.
Wrapping wire properly requires practice. Keep
in mind that a person’s wrist gets fatigued after
performing several hand wraps, which causes
subsequent wraps to get increasingly looser.
Knots in high-tensile wire reduce the wire’s
effective strength by about 30 percent.
Make joins in polywire by twisting the metal
conductors together separately rather than simply
tying a knot with the plastic strands included.
