Fencing Focus: How to build a portable fence

In this, installment we explain the in’s and out’s of portable electric fencing.

If you are after a temporary electric fence solution, a portable electric fence system is an effective temporary barrier for short-term animal control and rotational grazing. They’re easy to assemble and use – and can be powered by Gallagher mains, battery or solar/battery systems.

The main uses of portable electric fencing are:

  • Break feeding pasture and crops
  • Short term animal control
  • Intensive grazing
  • Impromptu fencing - silage stacks / hay bales

Portable electric fencing has many benefits:

  • Fast and easy installation
  • Re-usable / portable
  • Cost effective
  • Convenient to transport / carry

Here are the basics you need for a portable electric fence:

  • Electric fence energizer
  • Battery
  • Earth (grounding) system
  • Reels
  • Polytapes, wire or braids
  • Portable fence posts
  • Connector leads
  • Insul-grip handles

Below are some simple step-by-step instructions on how to erect your portable fence:

  • Connect the end of the wire/tape to an anchor point and walk toward the other end of the proposed fence line, carrying the reel and sufficient pigtails for the completed fence.
  • Allow the reel to unwind as you walk and place a pigtail standard about every 15m (depending on the terrain, this distance maybe shorter).
  • When you reach the end hang the reel on the anchor point, locate the ratchet and tighten the wire/tape (don’t over tighten).
  • If you are using a portable energizer e.g. Gallagher B11 - connect the green energizer lead to an earth stake, and the energizer red lead to the fence, and turn energizer on.
  • If the anchor point has mains power adjacent to it, connect power to the portable fence using a G63400 lead connector.
  • Check the fence voltage using a digital volt meter.

To design your own portable electric fence, see our website www.gallagher.co.nz under “Electric Fencing Products” which takes you through a shopping list of what you need to build your own portable electric fence to suit your particular property or situation. It is important to choose the correct energizer ensuring enough power for your fencing requirements. The first and most obvious choice is mains power if it is available, however the type of energizer best suited for your fence depends on the following factors;

  • Availability of a mains power supply
  • The amount of fence to be powered
  • The type of stock to be fenced

If there is a possibility of vegetation interfering with your portable fence some power may be lost from the fence, therefore a more powerful energizer may be necessary. Talk to your local dealer about choosing the most suitable energizer for your farm.

Portable energizers are generally operated by a 12 volt rechargeable battery or a 9 volt disposable dry cell battery. Strip grazers like the Gallagher B11 are designed for single reel systems and can be operated by 6 “D” size batteries or a 12 volt rechargeable battery. Batteries will need to be recharged as necessary depending on the size of the energizer, battery capacity and amount of use. The portable S16 energizer provides maintenance-free solar power operation with automatic battery recharging and is ideal for strip grazing.

Once you have chosen the correct energizer to power your fence, you will need to choose tape, wire or braid as the fence “wire”. Use Gallagher Poly, or Turbo products (rather than high tensile galvanized wire) on portable electric fences because they are light, visible and easy to wind on to a reel.

Tape is generally used where visibility is important. With the Gallagher Turbo Plus range we’ve drawn on our knowledge of animal psychology by replicating nature’s warning sign: Stripes. Proven to be more effective in deterring stock. (Note: Tape is not recommended in areas exposed to very strong wind. Polywire/Turbo Wire is preferable where wind or adverse weather conditions would “work” a tape to deterioration! Braid is a woven product designed not to “tangle” or overstretch.)

The above outline gives you a basic understanding of what you need when constructing a portable electric fence.
