The Basics of a Permanent Electric Fence
A good electric fence is a complete system. Each part plays a role in keeping power moving through the fence and livestock where they belong.
Energizer
Supplies the electrical pulse that powers the fence.
Grounding System
Provides the return path needed to complete the electrical circuit and is critical to good fence performance.
Posts & Braces
Support the fence. Corners, ends, gates, and changes in direction may require additional support.
Insulators
Keep electrified wire from contacting posts or other materials that can drain power from the fence.
Wire & Connections
Carry the electrical pulse throughout the fence. Good connections help maintain power across the system.
Gates & Crossings
Provide access while maintaining electrical continuity where needed.
Plan Before You Build
A little planning before installation can save time, materials, and headaches later.
Know Your Livestock
Plan wire number and placement around the livestock you need to contain. Smaller or more challenging livestock may require additional wires or closer spacing.
Map Corners & Changes in Direction
Identify corners, curves, ends, and major changes in direction before installation. These locations can affect post, brace, and insulator requirements.
Plan Your Gates
Decide where equipment, livestock, and people need access. Planning gate locations ahead of time helps avoid inconvenient changes later.
Consider Your Terrain
Hills, dips, uneven ground, wet areas, and changes in elevation can affect post placement and how the fence follows the land.
Plan Post Spacing
Line-post spacing depends on the fence design, terrain, wire type, livestock, and installation method. Use the Permanent Fence Calculator above for a starting material estimate.
Think About Power & Grounding
Plan the energizer location, grounding system, power source, and how electricity will be carried to all sections of the fence.
Planning a complicated fence?
Every farm is different. USA Grazing Systems can help you work through fence layout, materials, energizer sizing, and other system considerations before you build.
