Gates for Permanent and Temporary Electric Fences

Cable not well placed. The cable is not well placed it should be close to both the post and the goose neck to prevent.

Permanent Electric Fence

You have to think about how to transfer the electrified wire and the earth wire from one side of the gateway to the other. You can insulate cables underground or take them overhead on high poles. If you take it underground you must use double insulated wire or double insulated galvanised steel wire or underground cable (special plastic coated wire). Don’t use copper wire for the underground cable because you get a chemical reaction that causes the galvanised steel fencing wire to corrode.

The diagram Figure 1 shows how you could keep each live wire separate. If you do it this way you can have the bottom live wire switched off and it also makes testing easier. This can be an advantage in areas where heavy growth comes into contact with the bottom wire. It is cheaper to take the wires overhead, but this method is only successful if the gate posts are substantial and unlikely to move. You need long posts and supports and you have difficulty in keeping them vertical. The overhead wires might be damaged by wind or vehicles. The underground method is preferable, provided you can easily dig a trench. Use double insulated galvanised wire, preferably in poly pipe.

Polypipe is in place for the cable to come through and then he wired into the electric wires. This is a typical cow-calf-cattle fence. There are four live wires and an earth on top. The benefit of earth on top is that it helps to minimise the effects of lightning strike.

The underground cables need special protection if the soil is wet or if heavy vehicles use the gateway. You can protect them by running them through black polythene water pipe. If you use this method then you need to stop rain from running into the pipe. For example, turn the pipe ends downwards.
NOTE: Standard household electric insulation tape is not suitable for taking wires underground because the plastic breaks down when it is buried.
If you want to keep the live wires separate so you can test them more efficiently, then you need separate insulation for each wire.

Temporary Electric Fence

If you have a gate in a temporary fence, you can use a gate break that usually has a hook and an insulated handle. The gate-handle should always be installed so it is only connected to the pulsed wire when it is hooked in. That is, when the gate is open, the gate and wire are no longer electrified.
An electrified bogan gate is ideal for this purpose. This gate is made with ordinary fence wire and plastic coated steel gate handles. See figure 2.
The bogan gate can be made any width. It is a good idea to have wide gates in electric fences so you can move stock through them. Gates 10 m wide are not too wide, even wider gates are sometimes used. Bogan gates have an advantage in that they cost less than other types of gate.
