People installing electric fences often make the
mistake of pulling the wire too tight. Pulling the
wire tight requires big corner posts and braces that
are overkill for one-wire and two-wire fences.
Only tighten wires enough to take most of the sag
out of them.
Along woodlands where trees or branches
might fall on fences, it is a good idea to include
tension springs to add some “give” to the fences.
Consider using tension springs where deer traffic
is heavy. Springs could prevent some damages to
fences and also save the inconvenience of having
livestock escape before the damaged fences are discovered
and repaired. Also, by driving posts on
alternate sides of the wire, only one insulator will
likely be damaged if a deer runs into the wire.
Spacing for posts and stays may vary from 40
to 150 feet, depending on the terrain. The posts
need to be closer on steep or uneven terrain.With
spacing at 150 feet, install stays to maintain the
proper wire height. The stays can be small fiberglass
posts, three-eighths-inch diameter or larger,
placed about 50 feet apart.
