How Does An Electric Fence Work?
An electric fence can be either battery or mains powered, converts the power into high voltage pulses. If the wire carrying the pulse is touched by an animal, the current passes through the animal to the ground, and this effect gives a shock. As the animal realises that the fence causes pain it quickly learns to stay away, and the fence becomes a physical and psychological boundary. Electric fencing is considered far safer than a lot of conventional fencing methods as the energiser emits the pulse once every 1-2 seconds and it lasts for only a fraction of a second whearas barbed wire has been known to cause injury to an animal. |  |
|
An electric fence is made up of 3 main components:
- An energiser which can be either mains or battery
- Conducting line which makes up the actual barrier. This can be electric nets, polytape, wire, polyrope or twine.
- Good insulation of the line so the power does not leak to earth
- An earth stake that takes the current back to the energiser.

Choice Of Electric Fencing EnergiserThis is the heart of the system! There are many models available depending on the power supply and output required, the fence length, and the type of animal to be contained or excluded. |
|
 | Mains Fencer / Energiser
These are best for large areas where a permanent electric fence is required. They are always the preferred choice for any electric fence where a 230v supply is nearby. The power can be taken from a mains energiser unit to the fence and the earth stake by insulated 'Lead Out Cable' which can be buried. With a mains energiser, the running costs are very low with no maintenance reqd |
|
Dry Battery 9v Energiser / Fencer
These are also very mobile fence energisers powered by large disposable batteries. Very popular for strip grazing and seasonal use by farmers and horse owners alike. The battery saving features on our Forcefield models allow the batteries to last longer and therefore lower running costs. |  |
|
 | Wet 12v Battery Energiser / Fencer
Ideal for semi-permanent electric fences or where no mains power is available. The 12v batteries are rechargable and these are generally able to power longer fences than dry batteries. While a car battery will power an electric fence, it is always better to use a 'leisure' battery because a car battery gives out maximum power over a few days and then the power dwindles over the weeks whearas a leisure battery gives the maximum power it can over the weeks and it will go from full strength to flat in a couple of days. This is termed 'deep discharging'. The higher the Ah of the battery, the longer between recharges. |
