Electrified high tensile fencing is an excellent choice for a permanent perimeter fence.
A high tensile fence system requires many unique components. While not right for every type of animal or enclosure, a high tensile fence is affordable, attractive, easy to maintain and long lasting — from 25-50 years.
Because the distance between posts in a high tensile system can be 30’–90’, and the wire is under tension, wood posts are recommended.
Line posts should be a minimum 4” in diameter, with 6-8” diameter posts used for corner posts and gate posts. In some cases T-posts may be used for line posts.
Post Length
When purchasing posts, be sure to allow additional length for sinking posts into the ground. As a general guide, the overall post length should be the depth driven into the ground, plus the height of the top wire, plus 2”.
Post Spacing
Post spacing depends on many factors, including the animal being controlled, the number of wires used, the number of spacers between posts, the amount of animal pressure (the more animals per acre, the less distance between posts) and the terrain.
The number of wires also determines the type of bracing used at corners and gate openings.
We recommend either pin lock or tube insulators for high tensile fence systems. Both allow the fence wire to move as needed.
High Tensile Corner & End Post Insulators:
Wrap Around Insulator – Slide wire through tube and wrap insulator around corner or end post. Secure with 2” barbed staple. Durable polyethylene with poly insert for added strength.
Donut Corner Insulator – made of unbreakable polycarbonate, extremely strong with 5,000-lb. tensile strength.
High-strain Corner Insulator - made of fiberglass reinforced nylon, engineered for full tension of 200,000 psi wire.
If electrifying your fence, you need to make electrical jumper connections between all electrified fence wires.
Use a length of 12 1/2 gauge wire as a jumper and connect it to a hot wire with one of the extra crimping sleeves placed on the “hot” fence wires prior to tensioning. Crimp to attach.
Then slide a section of insulated plastic tube, or insultube, over the wire to prevent it from touching the non-electric wires. Crimp.
Repeat until all electrified wires are connected. Next, install and connect your electric fence charger to the fence. Install indoors if AC-operated or outside in an enclosure if battery-operated. Use a low impedance charger with adequate joules to keep animals safely contained.
Use 20,000 volt hookup wire to connect from fence terminal on charger to the fence wire and from the ground terminal to the ground rod. For maximum fence performance, drive three 1/2” 6-foot galvanized ground rods into the ground. Space them about 10 feet apart and within 20 feet of the charger. Connect them using 20,000 volt hookup wire and brass ground rod clamps.
Maintenance of Your High Tensile Fence
Your high tensile fence system is now ready to provide safe and effective animal control for many years to come.
Don’t forget that regularly walking your fence to check insulators and keep wire free of debris will help to keep your fence delivering top performance. Check for tree branches or weeds that may be drawing power from your fence.
A voltage tester is a good investment to help you troubleshoot short circuits and determine that adequate voltage is on the fence line.
