Electric Fence Prices in South Africa
There are a number of factors that affect electric fence prices. In order to provide an accurate estimate, a certified electric fence installer must consider a number of factors.
It is therefore not possible to provide a rate per meter for an electric fence.
- Height and design of the wall on which the fence needs to be erected
- Type of fencing (wall top, standalone etc)
- Height of the fence to be erected.
- Number of zones required
- Smart installations such as networking energisers via LAN and wireless
- Difficulty in accessing the fence
- Length and laying of HT cable
- Paving
- Lifting concrete and other obstacles
Electric Fences Energisers
Electric fence prices may also vary depending on the selection of the energizer and the number of zones. A variety of energisers are available from us, including medium and high-powered models. The size, number of units, and type of energizer will affect the price of an electric fence.
Aluminium, galvanised steel, and stainless steel wire that is used for electric fencing have different levels of conductivity. When designing a fence, you must take into account the advantages and disadvantages of each material.
Choosing the right energiser will depend on the length and type of wire and cable of the fence.
High Tension (HT) Cable
Electric fencing uses HT cables to conduct high voltage to and from areas where bare wires cannot be used.
It is extremely important to use HT cable of high quality to prevent breakdowns, especially underground, where the problem may be difficult to locate and replacement may be costly. HT cable should be buried at least 30cm underground in conduit.
Planning your Electric Fence Installation
The more steps, corners, or pillars you have in your installation, the more wall brackets you will need. Inexperienced installers typically make this mistake the first time they install electric fences.
Length of the fence- Fencing brackets should be mounted approximately every 3 meters. Brackets are installed to insulate the wires and the further apart the brackets are the easier it is to separate the wires.
- Amount of steps in the wall design
- At every step in the wall the brackets should be doubled up. This will guarantee that intruders cannot enter the electric fence through any gaps.
- Number of pillars
- Wall pillars that protrude from the wall should be wrapped with brackets to prevent intruders from getting a foothold on the wall.
- Number of corners
- Two posts per corner should be used with one stay per post. One post/bracket will cause the wire to sag over time.
- Amount and types of gates
- There is a need for two additional posts and extra posts for the steps down to the gate
- Stays
- Stays keep electric fence brackets from bending inwards under tension. At every corner or change in direction of the wall, they should be placed no more than 50 meters apart.
- Tensioning
- Every 50 meters and at every corner or change in direction of the wall, a tensioner should be installed to ensure adequate tensioning.
- Unusual problems
- Every fence has its challenges when installing
Length of the fenceTechnical Installations
Electric fences have evolved over time, as have communication and notification methods. Using wireless networks, we can now set up zones where energisers can communicate with each other over long distances. Electric fence installation requires experience and expertise, which in turn affects the price.
Building a fence around a large property must be divided into manageable sections to make finding an intrusion easier when the alarm is triggered. To establish the zones, it may be better to use wireless network rather than HT cable, which has its own challenges.
