Electric Fencing

Electric Fences

signAn electric fence is a barrier that uses electric shocks to deter animals or people from crossing a boundary. Most electric fences are used to enhance the security of sensitive areas, such as military installations, prisons, and other security sensitive places, for agricultural fencing and other forms of animal control.

Electric fences are designed to create an electrical circuit when touched by a person or animal. The energizer converts power into a brief high voltage pulse. One terminal of the power energizer releases an electrical pulse along a connected bare wire about once per second. Another terminal is connected to a metal rod implanted in the earth, called a ground or earth rod. A person or animal touching both the wire and the earth during a pulse will complete an electrical circuit and will conduct the pulse, causing an electric shock. The effects of the shock depend upon the voltage, the energy of the pulse, the degree of contact between the recipient and the fence and ground and the route of the current through the body.

Security Electric Fences

Security Electric Fences are electric fences constructed using specialised equipment and built for perimeter security as opposed to animal management. Security electric fences consist of wires that carry pulses of electric current to provide a non-lethal shock to deter potential intruders. Tampering with the fence also results in an alarm that is logged by the security electric fence energiser, and can also trigger a siren, strobe and notifications to a control room or directly to the owner via email or phone. In practical terms, security electric fences are a type of sensor array that acts as a physical barrier, a psychological deterrent to potential intruders, and as part of a security alarm system. Multi-zone security electric fence used alongside a physical barrier. Non-lethal electric fences are used by domestic, private and government-sector bodies to prevent trespass. Many of these electric fences act as monitored security alarm systems in addition to causing an uncomfortable shock.

Walltop Electric Fence

electric-fencingHere six or more electrified lines are installed on top of wall. Poles are fixed at a maximum distance of 3 m from each other. Standard heights over wall surface are

  1. 600 mm(6 lines),
  2. 800 mm (8 lines),
  3. 1000 mm(10 lines)
  4. 1200 mm (12 lines)

Wall top electric fences are a good, economical, aesthetic and more effective alternative of barbed wire and concertina coils.

 

Free Standing Electric Fence

freestandingFree standing or ground up electric fences is generally a second line of defence after a wall or other fence system. However, there are direct freestanding installations also. Freestanding electric fence generally has strong strain points and strong corners, as they take the entire load of wires and intermediate poles are comparatively lighter. Cement foundation is required only for the Strain and corner poles, intermediates are directly hammered inside. Standard heights over ground level are:

  1. 1800mm (20 lines)
  2. 2400 mm (24 lines)
  3. 3000 mm (30 lines)

 

 

Piggyback Electric Fence

securo3These are combination of two fence types like chain link fence + electric fence, industrial weldmesh fence + electric fence, 358(anticlimb) fence + electric fence. This type of fence has many advantages over systems discussed above as you get the desired strong physical demarcation as the wall, yet it is see through and you get detection and deterrence by virtue of electric fence. Electric fence is either installed on top of the fence or from ground level up and continuing above the fence but taking support of fence poles. Such fences are quicker, economical and more secure than building a wall.

Agricultural Electric Fences

Electrified-Game-FencePermanent electric fencing is used in many agricultural areas, as construction of electric fences can be much cheaper and faster than conventional fences. The risk of injury to livestock, particularly horses, is lower compared to fences made of barbed wire or certain types of woven wire with large openings that can entangle the feet. Many fences are made entirely of smooth high-tensile wire.

Conventional agricultural fencing of any type may be strengthened by the addition of electric lines mounted on insulators attached to the top or front of the fence. A similar wire mounted close to the ground may be used to prevent pigs from excavating beneath other fencing. Substandard conventional fencing can also be made temporarily usable until proper repairs are made by the addition of a single electric line set on offset insulators.

In practice, once most animals have learned of the unpleasant consequences of touching the fence they tend to avoid it for considerable periods even when it is inactive.
