Electric fences are commonly used for livestock control, but can also be used to secure home and business premises.
Usually seen installed on top of walls so that intruders are limited to jumping the wall, electric fences are convenient, intimidating and useful for keeping unwanted persons of your private property.
Electric fences are made up of electric energisers which charge using transformers and then release the power they have generated to generate the electrical pulse that will be used to shock the intruder.
Like any electric system, electric fences work using a circuit. Electrical circuits are composed of individual parts such as resistors, transistors. The resistor and transistor components allow electricity to flow from one point to another.
Components that make up an electric fence amongst the energiser are wall top brackets, energisers and the wire. While the wire and brackets allow for the structure of fencing to be held up, the energisers, as mentioned above, release the electric shock when needed.
With this being said electric fences allow the power from the electric energisers, generated from the transformers or any power sources to flow from one point to another, creating a circuit that is ready to give off an electric shock when touched.
Back up battery systems are installed in case of absence of electricity and can provide readily available power up to 10 hours.
Another additional feature that can be added is a lightning diverter which will protect the energiser from being possibly damaged by lightning.
With that being said, there are different types of electric fences a home and business owner can choose from:
Electric Fence Located on a Wall
These are the most common electric fence types and can be seen in almost any metropolitan area in South Africa.
For an electric fence to be installed on a wall, the wall has to be higher than 1.5 meters long.
With these types of electric fences, different pole designs can be used to connect the electric fence wire to the power box, and these can range from T-piece shaped poles to straight standing poles.
These electric fences are more affordable and can be used for long-term purposes.
Electric Fence Located Around a Perimeter
This type of electric fencing is mainly used to secure plots, animals and other forms of business premises.
This type of electric fencing cannot be used for securing a home as it poses dangers to domestic pets and vulnerable individuals such as children.
The initial purpose of this electric fencing was for agricultural reasons to keep livestock within the marked perimeter.
This fencing can also be used to intimidate and prevent intruders from stealing equipment and merchandise which is stored outside.
With electric fences, one must keep in mind a few considerations before installing electric fences.
These considerations include:
- If the electric fence is going to border your neighbour’s wall, consent must be sought;
- Wall must be higher than 1.5m;
- Perimeter fencing, for example, would be less likely used in a residential home for safety purposes;
- You cannot install electric fences alongside barbed wire;
- Ensure that you get a qualified installer who can advise you on the type of electric fence that will suit your needs;
- Also, ensure that you get an installer that will make sure the electric fence is installed correctly;
- Warning signs should be clearly seen to warn intruders and victims
Advantages for electric fences at home and business are:
- Intimidates intruders and keeps them from entering
- Long-term security investment
- Can be connected with the primary alarm system and can sound an alarm when triggered
- Outdoor equipment is safe
- Long-term security investment
- Keeps intruders out of business premises
- Low maintenance
- Easy to construct
- Does not consume much electricity
- Protects pets and loved ones
Electric fences have been tested over time and have proved to be valuable investments that can work for both business and home. Whether it is to keep your family safe, your livestock from wandering or your trucks from being stolen, keeping intruders out has never been easier.
Electric fencing is a recommended form of security. Ensuring regular maintenance can prevent broken electric fences which may look all right, but can be bypassed because of any faulty wear.
