We can assist you with a new electric fence installation or lengthening your existing fence. An electric fence is a barrier that is made up of various metal parts that carry an electric charge. It is designed so that any person or animal that tries to get through the barrier is shocked. The shock is not lethal; rather, the aim is to ensure that the animals or people stay inside or outside of the barrier.  
New Electric Fence Installation
An electric fencing system consists of a number of parts. Each of these is important in setting up the fence so that it can create a shock when there is a break-in attempt. Some of the main parts of an electric fence installation include:   All electric fences must be installed, operated and maintained according to the Electric Fence laws; therefore it is important that you choose a reputable company for your electric fence installation.


Type of electric fence installation:

There are three main types of electric fencing systems: Piggyback:
Piggyback Electric Fence
Firstly, there is the piggyback electric fence installation. This is when the electric fence is installed on an existing fence thereby making the area more secure. The piggyback profile is fastened to the existing fence post (pillars or a palisade fence) using rivets or screws. As a result, the electric fences is supported by the structure and strength of the existing fence. Wall Top:

Secondly, there is the wall top electric fence installation. In this case, the electric fence is attached to the top of an existing perimeter barrier eg: Masonry wall or a precast concrete wall. Stand alone:

Thirdly, there is a stand alone electric fence installation. This is where the electric fence is the only barrier.   Now let’s turn to a quick overview of some of the main parts of an electric fence:

Electric fence installation – Energizer

Electric fence energizer
The energizer – also known as the electric fence charger – is the driving force behind an electric fence. It is the part that passes the correct current on to the wires of the fence. The energizer also monitors if there are any problems on a fence – for example, somebody has tried to cut the wires or jump over it – and can sound a warning alarm. It is important to choose the correct energizer when installing an electric fence otherwise it will not function optimally. Often we found that the energizer that has been installed is too small for the fence requirements. The size of the energizer required depends on the length of the fence, the type of wires used and various other factors.


Electric fence installation – Wires

New Electric Fence Installation
The electric charge runs along the electric fence wires for the length of the fence. In order to do so, the wires must properly installed. The wire tension is important as you don’t want wires to touch and affect the functioning of the fence. Wires must also be joined by secure connections to prevent disruption to the path of the electric charge. Wires must also be insulated so that they don’t touch the fence posts.

Electric fence installation – Cables

New Electric Fence Installation
Cabling is used to transfer the charge from the energizer to the wires and then back again. It is also used to transport the charge from one wire to the next. The cabling must be specifically manufactured for electric fencing in order to handle the high voltages (10 to 14 gauge wire insulated to 20,000 volts). Normal electrical wiring cannot be used as it is rated for only 600 volt use.

Electric fence installation – grounding rods

Electric Fence Installation Grounding Rod
Grounding rods are an integral part of the electric fence functioning. These are metal poles that are driven into the ground and complete the electric circuit. When an animal or person touches the electric fence, the charge passes through them into the ground and from there to the grounding rods; then up the wires to the grounding terminal of the energizer (electric fence charger).


Electric fence installation – posts

Electric Fence Installation Post
Free-standing electric fences use posts that are driven into the ground to support the wires. These posts can be made of wood or steel and can be round or angular, depending on your requirements. The spacing of the posts depends on the terrain. If the lay of the land is relatively flat, the posts can be further apart than if the area is uneven. Electric fences  posts must be installed perpendicular to the ground.  

Electric fence installation – Wall Top Brackets

Electric Fence Brackets
When it comes to an electric fence installation on top of an existing wall (i.e. wall top electric fences), the wires are supported by various types of brackets that are attached to the wall. The bracket design that is chosen for the electric fence depends on what type of wall it will be mounted on i.e. brick wall, precast concrete slabs etc. If required, stays can be used to keep the wires taut.

Electric fence installation – Warning Signs

New Electric Fence Installation
All electric fences mus have warning signs along them to ensure that people are aware of the potential shock and dangers. There are many rules governing both how the warning signs should look as well as where they are placed and how many are needed. Whether your fence is a new install or is being repaired, the addition of warning signs is a legal requirement. All electric fences must be checked regularly because this will ensure that any issues are identified early.  Repairs can then be done immediately; therefore ensuring your safety. The most common electric fence components are manufactured by Nemtek and Stafex.
