Electric Fence

Normal fences only provide a passive physical barrier for your perimeter. Electric fences are an economical way of adding an active layer of security with a minimum of infrastructure changes. Not only do they provide an extra deterrence with a high voltage electrical shock,

Fences, regardless of their type, are used to prevent intruders or trespassers from accessing homes, commercial properties, and high-security areas. Using an electric perimeter security fence is an effective way to protect your property and valuable assets.

In addition to the high-voltage electricity that passes through them they can offer warnings via sensors if the fence is being tampered with.

How does electric fencing work?

The heart of your electric fence is the energizer. This device produces the high-voltage electrical pulse that is transmitted around a multi-wire perimeter fence. The strength of the shock depends upon the power available from the energizer, and the total resistance of the circuit.

Guardarm supply a range of energizers to support domestic and light industry security requirements, through to high security fencing where dual zones, networking and large fence systems are required. Guardarm only uses products which are of excellent quality and have fast turnaround time on repairs. At Guardarm we also service, repair and maintain most electric fencing products in the market place.

Reasons To Install An Electric Fence

  • Effective protection through high voltage shock
  • Psychological deterrent
  • Physical barrier
  • Early detection through alarm warning
  • Connectable to armed response
  • Internal battery backup
  • Power saving
  • Lightening and power surge protection
  • Remote fence monitoring
  • Low maintenance costs

Electric Perimeter Security Fences Offer Several Advantages

Deterrence, Detection, and Delay

Electric perimeter security fences deter potential intruders from accessing your property, standing in their way as a physical, intimidating barrier. While the shock these fences deliver is non-lethal, it’s enough to stop most people in their tracks, delaying their attempt to steal your assets or materials.

Should someone attempt to cross the fence barrier in spite of the electric shock, high-security options such as intruder alarms will detect the intruder’s presence when they access your property. In addition to detecting security breaches, intruder alarms will also alert you to doors being opened or devices being tampered with.

Ease of Installation

While electric fences should always be installed by professionals, they’re known for being easy to install, use, and maintain. Rather than incurring extra cost of building brand new fences, electric perimeter security fences can be installed parallel to or on top of your existing fence structure. Traditional fencing materials are heavy and sometimes difficult to transport, which can add to the cost and time it takes to get them installed.

Fewer Maintenance Costs

Electric fences are composed of steel or aluminum wires that have been coated with a protective material to prevent rusting. You don’t have to worry about damage caused by precipitation, and there’s no need to paint or re-stain the material like you would for a wooden fence. The basic maintenance these fences require include checking for adequate voltage in the wires with a voltage meter, preventing grass and other objects from touching the fence, and checking the connections.

Electric Security Fences are a smart way to protect our property


Almost any existing fence structure can be modified to include an electric fencing component. It can be added to the top of a fence structure to deter intruders from climbing over, or at the bottom of a security fence to stop trespassers from crawling under. It can be installed on cement walls, chain-link fencing, and even decorative wrought iron fencing.


When compared to an intrusion deterrent like barbed wire, electric fences are a safer way to secure your property. Barbed wired can cause potentially fatal injuries, while an electric perimeter security fence delivers a non-lethal shock that can have its voltage adjusted up or down.


It is important to regular check your fence and do ongoing maintenance. The most common repair to an electric fence is due to rust. Rust occurs because of wear and tear, acid rain and the harsh South African sun. Any of these will cause the fence wire to rust and deteriorate and it will need to be replaced. If the fence wires were not joined correctly when installed you will also find corrosion and breaking of the wire at these joins, due to the electrolytic effect.

Bobbins can get cracked by sun and energizers can get damaged by power surges or lightning storms. Remember to check your energizer battery and replace old batteries regularly. It is not recommended that you do electric fence repairs yourself. Rather leave it to the professionals who have the expertise and knowledge to repair your fence as good as new.
