Electric fence kits: make the right choice

An electric fence is an alternative to barbed wire to prevent animal intrusion into a well-defined area such as a vegetable garden. The necessary materials are offered in a kit to facilitate the user's task.

An electric fence kit includes various elements:

- an energizer, also called an impulse generator;

- conductors (steel wires or ribbons);

- insulators, whose role is to isolate the conductors from the supports;

- stakes serving as supports for the conductors;

- a battery or a dry cell to power the energizer.

Several parameters should be considered when choosing the energizer.

- The user can choose between models that plug into the mains or are battery-powered, depending on the availability of electrical sources. Battery-powered models are often delivered with a solar panel to recharge the battery.

- The power of the device depends on the size of the animal. If a minimum voltage of 4,000 V is necessary for cattle, a less powerful electric shock is suitable for small domestic animals like dogs and cats. Conversely, wild animals, sheep, and goats require a more powerful device.

- The impulse energy delivered by the energizer must be adapted to the length (perimeter) of the fence. The rule is 1 joule (J) per kilometer.

The conductor should also be chosen based on a few parameters.

- Visibility is to be considered since the sight of the device can deter animals from entering the protected perimeter. Ribbons offer increased visibility for horses, dogs, and cows.

- Conductivity is also to be considered. Indeed, it translates to the ability to maintain a high voltage at the end of the line. Steel wires and ribbons benefit from optimal conductivity.

- Resistance to breaking and corrosion is also a criterion not to be overlooked.

Thus, the choice of an electric fence kit depends on the availability of electrical sources, the perimeter to be protected, and the animals concerned.
