Introduction: What is an Electric Security Fence?
An electric security fence is a barrier that uses an electric pulse to deter people and animals from crossing. It works by delivering a non-lethal shock upon contact, which serves as a physical and psychological deterrent. Commonly used for residential, agricultural, and industrial purposes, electric fences provide a reliable security solution.
How Does an Electric Fence Work?
An electric fence operates using an energizer that generates electrical pulses. These pulses travel through the braided wire of the fence. When a person or animal touches the fence, they complete the circuit, causing a mild electric shock. For security fences, this action also sends a signal to the energizer, which can trigger an alarm or strobe light to alert you to potential tampering.
Materials Needed for Electric Security Fence Installation
Energizer: Powers the fence by sending electric pulses.
HT (High Tension) Cables: Connects the energizer to the fence.
Braided Wire: Forms the main body of the fence.
Line Clamps: Secures connections between wires and cables.
Ferrules: Joins wires and maintains tension.
Soft Wire: Used to attach tensioning springs to fence posts.
Fence Posts with Insulators: Supports and organizes the wires.
Surge Diverter: Protects the system from lightning or power surges.
Tensioning Springs: Ensures the fence wires remain taut.
Earth Electrode: Grounds the system to safely disperse excess electricity.
Siren and Strobe Light: Alerts you to tampering or security breaches.
Caution Signs: Warns the public of the electric fence.
Functions of the Materials
Energizer
The energizer is the core component of an electric fence. It sends electrical pulses through the braided wire and ensures the system’s functionality.
HT Cables
These cables carry electricity between the energizer and the fence. They’re designed to handle high voltage safely.
Braided Wire
The braided wire forms the fence’s active barrier. Durable and conductive, it’s available in rolls of up to 680 meters.
Line Clamps
Line clamps ensure secure connections between wires and prevent loose or faulty wiring.
Ferrules
Ferrules are small but essential. They secure tensioning springs to wires and help join high-tension cables.
Fence Posts and Insulators
Fence posts hold the wires in place, while insulators prevent electrical leakage and ensure efficient operation.
Surge Diverter and Earth Electrode
These components protect the system from lightning strikes and safely ground excess electrical currents.
Siren and Strobe Light
The siren sounds an alarm, and the strobe light provides a visual alert in case of tampering.
Step-by-Step Guide to Electric Fence Installation
1. Mounting the Fence Posts
There are two common methods to install fence posts:
Wall Drilling: Drill holes into the wall and secure posts using plugs and screws.
Embedding in Concrete: Drill or chisel holes into the wall, insert the posts, and secure them with a mortar mix (quarry dust and cement). Allow the mortar to dry for at least 24 hours before proceeding.
2. Installing the Braided Wire
Attach tensioning springs to the fence posts using soft wire.
Thread the braided wire through the springs and secure it with ferrules.
Tension the wires to ensure they’re taut and properly aligned.
3. Mounting the Energizer
Choose an accessible, weather-protected location for the energizer.
Use the manufacturer’s mounting template to drill holes and install the unit.
4. Connecting the Energizer to the Fence
Connect HT cables from the energizer’s power terminals to the fence wires.
Designate two wires as earth lines and the rest as live (hot) wires.
Use the earth terminals to connect the energizer to the earth electrode via the surge diverter.
General Safety Requirements for Electric Fences
Electric fences must not pose a hazard to people, animals, or the environment.
Do not power the fence with multiple energizers.
Avoid electrifying barbed or razor wire.
Install warning signs along public-facing sections of the fence.
Ensure gates can be opened without risk of electric shock.
