Choose a good quality brand that meets international safety standards.

Respect the device's capacity in terms of mileage and maximum electrification distance. Example: Peon 120km Solar Kit: electrifies up to 120.000 meters of wire and reaches a maximum distance of 4.500 meters from the device to the furthest point of the fence.


Do not use line insulators that are installed inside the pole (hose). They have a large contact area, which can facilitate the oxidation of the wire through the accumulation of rainwater. It makes it difficult to see possible damage that may occur on the insulator. It requires more labor for installation, as they need to be fixed in holes drilled through the post.

Require insulators suitable for electric fences and that have protection against ultraviolet rays.


The following must be used for grounding: rods, angles, pipes, or posts that must be galvanized to prevent rust. Avoid using a “copper” rod.

It is necessary to carry out the main grounding (of the electrifier) ​​with at least 3 rods that must be buried close to the device, preferably in a humid place. The rods must be at least 2 meters long or as long as necessary to reach the moist part of the soil.

The rods must be interconnected, preferably using the same wire as the fence to join them.

In regions where the soil is dry, sandy or has low conductivity, it is advisable to place auxiliary grounding made with rods connected to the neutral/earth wire of the fence. The distance between these rods can vary between 1.000 and up to 300 meters between them.

Neutral or ground wire: It is a continuous wire that runs along the entire length of the fence, running parallel to the electrified wire(s). All main or auxiliary grounding rods are connected to this neutral wire.


Use wire suitable for electric fencing. They are better conductors than conventional fence wire and do not oxidize easily.


Always install a protector to reduce the incidence of lightning that can reach the energizer. There are several types and brands on the market. But remember that no device guarantees 100% efficiency.

These systems serve to direct part of the electrical discharge (lightning) to the ground through grounding, preventing it from reaching the electrifier with its full charge.


Electric fences require periodic maintenance. It is important to define someone responsible for this task, which can be quite simple. An inspection must always be carried out to make sure that the insulators are intact; remove vegetables that may be touching the electrified wire; measure the voltage of the fence using an appropriate voltmeter.

It is recommended that the voltage should be a minimum of 5.000 and a maximum of 9.500 volts.

An electric fence is a system where all its parts (electrifier, insulators, grounding, wire, lightning protection and maintenance) must work perfectly for the fence to produce good results.
