High Tensile Wire Tensioning Tips from Zareba® Systems


In this segment, you will learn where to
place strainers. How to install in lines strainers and tension indicator Springs. You will learn
how to apply tension to a wire and repeat the process for all of the wires
of your fence. You’ll learn the proper technique for
safely tensioning wire. How to accurately measure wire tension
and the proper use of multi groove poly spacers to prevent fence wire
separation. You are now ready to install in lines strainers and tension indicator Springs, unless you
are using self regulating strainers and then apply tension to the wire. Generally, you need one in line strainer
for every four thousand feet of wire. Locate strainers in the middle of each
fence span, where the poll in both directions will
be equal. A fence span: is the area between corner
or end posts. Every friction point, corner, dip and
rise reduces the strainers tension capacity by five hundred feet. After you have determined the in line
strainer location, cut the fence wire at that point. Place three 12 .5 inch gauge crimping sleeves
on the wire and preform the wire. Place the wire
through the hole in the in line strainer strap. Bend the wire back onto itself, allowing
the crimping sleeves to slip into place. Crimp the three sleeves to permanently
attach the strainer to the wire. Place the other end of the wire through
the hole in the strainer reel. Tension the wire with a strainer
handle. The compression clip on the in line
strainer eliminates the need to put your fingers near the bail, when applying tension, which can be very
dangerous. On the second wire from the top, install a strainer and tension indicator
spring to measure wire tension on the fence. If you are not using self regulating in
lines strainers, the spring features full strength tug links with marks to
accurately measure wire tension. To install, pull out one tug link and
thread it through the hole in the in line strainer strap. Next, reinstall the tug link back into
the spring coil and attach to fence wire using two crimping sleeves. Now, tension the wire. As you pull the wire using the strainer
handle, the tension indicator spring will compress. The first notch indicates 150 pounds
of tension. When the second notch appears, you’ve
reached the final desired tension of 250 pounds. Now, apply the same tension to all other
fence wires. You’ll be able to see and feel when all
the wire is properly tensioned based upon the first wire installed with the
Spring or self-regulating strainer. So, you will not need attention spring on
the other strands of fence. The next step, is to install the multi
groove poly spacers that prevent fence wire separation. Place poly spacers about 10 feet apart
between fence line posts. Spacers help maintain wire spacing
allowing line posts to be placed further apart. Use a class 3 galvanized wire clip to
attach spacers directly to the fence wire. A
wire twisting tool simplifies the clip installation.
