Double Wire Electric Fencing

Double Wire Electric Fencing is of the most efficient and cost effective barriers around farmland where livestock is kept. In an ever changing world, rapid technological advances make electric fencing projects so much simpler. Nevertheless common problems still exist no matter which type of metal fencing will form the basis for the electrical current. These can be avoided with a little technical knowledge and some common sense.


If the grounding is poor the electric fence will fail. It must complete an unbroken circuit if it is to deliver a shock. The normal installation formula is to position a minimum of three galvanised rods at a depth of 5 ft, 10ft apart.

Good quality ground rod clamps should be used to connect the rods but make sure that the metal you use is identical. For example if you mix copper with steel electrolysis will occur and your connections will rust. This will weaken the shock potential. If the ground bed is smaller than it should be you may notice too high a voltage in the ground rods.

Double wire fencing electric energiser

An energiser which is too small for the type of fencing you are using will not work effectively; resulting in livestock perceiving only a physical barrier rather than a psychological one which will cause pain when attempting to breach. The size of your fencing charger is crucially important if the barrier is to function properly.

So what size do you need?

Primarily consider the type of livestock you have, the quantity of fencing required and whether or not it is to be installed on a concrete base or soil where there’s a lot of vegetation. Between 3,500 and 5,000 volts is usually sufficient to contain most livestock. You’ll need a narrow pulse (low impedance) charger based on joule output. When purchasing an electric energiser (charger), be careful because unlike many things it might not be quite what it says on the box. For example, you might read that the charger will energise 80 kilometres of fence; but you need to make sure that this claim applies to double wire fencing or any other type of fencing you might be installing.

It’s always best to buy an energiser based on joule output and a reputable supplier will be able to advise you on what you need. This information is free so ask questions before committing to a purchase.
