Electric Fencing

Electric Fencing Suppliers stock and supply a wide range of electrical fencing products. Electric fencing can range from pest control, to prevention and intrusion into more specific areas such as office buildings and secure compounds etc.

Electric fencing suppliers offer security products, and these can be purchased in kit form and fitted by the purchaser, or can be supplied and installed by the suppliers.This type of fencing may be mains or battery powered, and many different systems are available to suit almost any requirements. For example : portable battery kits are extremely useful for the containment of livestock such as poultry etc., as they can be set up virtually anywhere they are required, and are very easy to dismantle and move to a new location.

Electric fencing suppliers can provide many accessories and these can include, electric fencing tape, rope, posts, netting and connectors and strainers.

Electric fencing systems are used widely for livestock and the type of system used will vary according to the type of livestock.

Some of these systems can include electric fencing for ;

  • Poultry
  • Horses
  • Dogs

Electric poultry netting is used for the containment and protection of chickens etc, and without this type of fencing, free range poultry would not be possible. Electric poultry netting is very effective at protecting poultry from predators such as foxes, yet also allows the poultry to roam free. These types of systems can be mains or battery powered. Other kinds of netting are available for sheep and rabbits.

The function of an electric fence is to deter people or animals from crossing a boundary. The electric shock from the fence can range from uncomfortable to very painful and in some cases may even be lethal. Electric fencing today is generally used for agricultural purpose, and is also frequently used to protect security sensitive areas. When an electric fence is touched by a person or an animal an electrical circuit is created. Electric fences make use of a component known as a power energizer which converts the power into a short quick high voltage pulse. An animal or person who comes into contact with the fence wire will complete the electrical circuit and conduct the pulse, this has the effect of causing an electric shock. The pain or effects of the shock will vary depending on the voltage and current used and also the amount of contact between the recipient and the fence or ground.

Electrified fences must be insulated from the earth and any other materials that conduct electricity. The fencing must not be fixed directly to metal or wooden posts, and avoid any vegetation, undergrowth etc. Wood or metal posts require porcelain or plastic insulators to be attached to them, and the fencing material wire etc, is then attached to the insulators.

Lethal electric fences are used for anti-personnel purposes, and were used in world wars 1 & 2.

Theft of Electric Fencing Energisers

By the very nature that a battery driven electric fence energiser is left in remote rural areas invariably on the edge of fields means that they are easy targets and liable to be stolen by itinerant thieves. It is very hard to disguise their presence as the fence itself is highly visible and probably several miles long so a thief has to simply follow the fence to find the energiser and purloin it leaving valuable livestock to be free to roam or removing the necessary protection from predators. Visualise a herd of Elephants free to enter human habitation due to the lack of electric current in the restraining fence.

Reports of energiser theft has been growing over the years as more people realise how effective they are. Regrettably the energiser is the expensive component of an electric fence making it a plum target.

There are various methods of reducing theft. The first is the use of an energised metal box. This is simply a metal box that is insulated from the ground with the energiser and battery enclosed. It is then connected to the energiser so is live in itself. This metal box will have upwards of 6000v attached to it so is a pretty good deterrent in itself and has proved successful over the years. Access to the box is usually by an insulated key so is reasonably user friendly whilst being reasonably effective. There have however been reports that the whole box has been taken probably by using insulating gloves to prevent the electric shock being effective.

Another method is to cover the energiser in a camouflaged cover in an effort to make it less visible. This has been ineffective as the fence itself is still highly visible and very simple to track back to find the energiser.

Recently a new system has been introduced on the market based on a GPS locating device and electronics that are able to register that the energiser has been tampered with. As the energiser is moved or removed from the input power source the electronics register this change and stimulate a text message to be sent to a pre set mobile number. It will then transmit a GPS tracking signal for 48 hours to a mobile App allowing you to track it and locate it.

The GPS Electric Fence energisers themselves have a warning that they may be tracked by GPS as a pro active theft reduction plan. The principle here that a thief will read it, change his mind about this particular energiser and decide to look for another target. The system is not only expected to reduce theft but also increase the recovery rate of stolen energiser. This is currently very low.

Excluding Badgers by Electric Fencing

Within Britain, badgers are particularly numerous in much of the south-west of England, and also in parts of the south-east and Wales. The Eurasian badger occupies a wide range of habitats. In Britain, numbers are highest in areas where there is a lot of old, well-grazed cattle pasture, but they also occupy mixed and arable farmland, forests, moor lands and coastal habitats such as sand dunes and cliffs. In addition, they also live in urban areas.

A large part of the badger’s diet consists of earthworms and grubs which they find in areas of short turf such as cattle pastures. In dry conditions during the summer, or in hard weather in winter, badgers may turn to gardens, Golf greens and fairways as substitute pastures, and excavate numerous holes in them as they dig for earthworms, leatherjackets, cockchafer grubs or other insect larvae. Sometimes the damage can be quite serious, with lengths of turf rolled back like carpets and left looking like giant brown and green Swiss rolls.

There are two methods of badger exclusion and both involve fencing. Firstly is the high tensile type that is highly ornate, involves burying the wire in to prevent badgers digging under and very expensive.

The next solution is to use an appropriate electric fence to give the badgers a sharp, but non-lethal “sting” on the nose if they try to get into a protected area. This can provide value-for-money for ceremonial gardens, putting greens, bowling greens and cricket pitches; for commercial planting schemes/shared allotments; and for large gardens. Electric fencing has been shown to be over 90% effective in excluding badgers in scientifically sanctioned trials.

There are two types of fencing applicable to excluding Badgers.

  1. Strained-wire fences consist of a series of electrified parallel conducting wires at varying heights above the ground. The conducting wires of strained-wire fences can be made from either polythene twine interwoven with steel strands (poly wire) or galvanised steel. The steel wire is a better conductor, far more durable and is cheaper but harder to work with.
  2. Electric netting fence consists of a woven net of poly twines containing electrical filaments. These are very easy to erect and move, very effective but are more intrusive and require larger energisers.

If both fence types are maintained properly they are equally effective. However, galvanised steel fences appear to be more effective than their poly wire counterparts.

Electric fencing systems are very light and simple to understand so lend themselves comfortably to DIY possibilities.

The strained-wire fence system is constructed of four electrified parallel conducting wires at heights of 10, 15, 20 and 30cm (4, 6, 8 and 12 inches) above the ground. The wires, which are all live, are held by adjustable plastic insulators supported on wooden stakes. A very viable alternative is to use plastic “tread-in” posts similar to those employed in horse yards as they provide both the posts and insulators in one item. The corners and ends are normally more robust wooden posts with insulators applied.

Electric netting fences vary in height and mesh size, and come in 50m rolls fitted with spiked posts at regular intervals and a clip at each end to join rolls together. Pegged guy ropes are also supplied with each roll to support the fences at the ends and at bends. These fences are very easy and quick to erect and dismantle but do require stronger energizers and require more maintenance to keep the vegetation away from the bottom strands.

The electric fence needs to be used between dusk and dawn for at least a few weeks (i.e. until each visiting badger has had a “sting” on the nose). The best guesstimate is that they will remain effective for at least 95% of badgers who have been stung (as exceedingly few like to receive a second sting). This means that after the initial few weeks, you can take the risk that the fence can be left in situ, but left non-electrified during the day and operated at night.

Electric fences must be powered by a specialised energizer (which gets its power from the mains or from a 12v battery). If you use a 12v battery, you will need two batteries, so you can charge one up on a trickle-charger, whilst the other one of electrifying the fence. An alternative is to use a solar panel.

When badgers encountered the fences for the first time their initial response is the same as would be expected for any unfamiliar object. In most instances, badgers approach the fences cautiously before investigating, usually with their noses, which are poorly insulated and highly innervated. Any individual touching an electrified fence with their nose will, therefore, receive a sharp shock and subsequently learn to avoid the area. Investigatory behaviour of this nature should therefore be encouraged and a number of approaches are being used to achieve this. The best solution to this is to attach specific bait caps to the fence. These have an absorbent centre that is then soaked in an attractant such as syrup or neat Apple cordial for the first week or so.

Badgers that have definitely been seen to touch the electrified wires generally responded by retreating immediately to the nearest harbourage. This response was most marked when the badgers concerned touched the electrified wires with their noses. Badgers do not appear overly stressed by the receipt of an electric shock and will move in the close vicinity of the fence without touching it again.
