Electric Fences 

Types of fences

Electric can construct various types of Electric fences depending on requirement and budget, mostly focused on functionality at an affordable price

1. Livestock control

a. Horses

i. Horses are very sensitive to the electric impulse and therefore only need a light Energizer with typical flat barrier tape 850mm from ground level

ii. Once the horses are used to the barrier, the energizer will most probably not be required


b. Cattle & Sheep

i. Mostly used for programmed grazing or camps

ii. Energizers from 2 Joule (3km) up to 5 Joule (8km) will be suitable on short barriers with one continues wire.

iii. If more live wires are used in parallel then the total wire length must be calculated with the std. Resistance Formula

2. Game control

a. Ordinary

i. Similar to a cattle fence with typically 19 wires (1900mm high), alternatively live and earth wires. All the live wires are in parallel and all the earth wires are in parallel

ii. No indication on the energizer if the fence is cut


b. Big Game

i. As above with 24 wires (2400mm high)

c. Problematic Game

i. Various configurations depending on the type of game to be controlled. Contact for a quote

3. Security


a. Farms & Small holdings

i. Starting at 1500mm and going up to 3000mm

ii. Most powerful energizers affordable. (true 8Joule by law)

iii. The configuration will normally be as follow

1. dense at the bottom (50mm apart) gradually opening up to 150mm, with dense middle sections and opening up to the top

2. the type of protection will determine what type of Energizer must be used, normally the most powerful allowed by law or the tradeoff between power and affordability

3. we recommend to go for power, it talks in the neighborhood

4. in-line earth loops and ground earth loops on bottom wires (up to 800mm from ground), this also improve the earthing on your fence


b. Urban Houses

i. Mostly wall-top type of fences, ranging from 5 wire to 8 wire

ii. Piggyback of existing prefab and brick walls become very popular as burglars tend to break the walls at the top and climb threw see photo

iii. Energizers by law may not be more than 5Joule output energy for urban areas

iv. The lowest live wire must be 1800mm from ground


c. Security Complexes


i. Same as for domestic applications

ii. The trend is to split the fence and install a second Energizer feeding the other half of the fence.

This method holds a few advantages

1. We increase the shock shorter live wires, not exceeding 500©

2. we now zone the fence identifying the targeted area

3. we increase the reliability probability of 50% still live, if cut
