The Gemi electric fence - 100% Made in Italy - is used to ward off wild animals such as wild boars, deer, foxes, etc.
The purpose of electric fences is to protect the territory from unsightly invasions. It is also used to contain animals such as cows, sheep, pigs etc.
It has nothing to do with hunting. We have all the legal certificates available to produce and sell electric fences. This is the only legal solution for those who want to protect their plantations.

Ring Insulators
Gemi Elettronica patented its ring insulator design in 2019, producing a component that is measurably larger, more wind-resistant and more durable than conventional alternatives. Designed specifically for wooden posts, the insulator locks both polywire and tape firmly in position using a windproof retention clip that eliminates the conductor movement responsible for most fence faults on exposed sites. Gemi ring insulators are sold in packs from 10 to 100 units. Order direct from the manufacturer for factory pricing and UK delivery in 24–48h. Compatible with all Gemi conductor cross-sections and standard third-party polywire up to 6 mm².
Designed for wooden posts
The ring insulator snaps onto a round wooden post without tools and without drilling. The fixing geometry spreads the clamping load across the post circumference to prevent loosening under vibration caused by wire tension or animal contact. Conductors from 2.2 mm² up to 40 mm tape are held in the same insulator body, meaning a single product covers the entire Gemi conductor range for wooden post applications.
Windproof retention system — patented 2019
On open moorland, upland pasture and coastal sites, conventional insulators allow conductors to be lifted by strong gusts and flicked onto the post or adjacent vegetation, creating earth contact that drains energiser output. The patented Gemi clip prevents vertical displacement, keeping the conductor at the designed stand-off distance regardless of wind speed. CE certified and tested for prolonged UV exposure without brittleness.
Compatible with wire, tape and rope
The same ring insulator accommodates Gemi polywire in all cross-sections, electric fence tape up to 40 mm wide and braided rope conductors. No dedicated tape insulator or rope insulator is needed for wooden post installations, simplifying parts inventory for farms using mixed conductor types across different paddock configurations.
Questions and Answers
The electric fence for animals is neither dangerous for people nor for animals. As with everything, even for electric fences there is a standard that establishes the values to be respected.
The fence energiser is a product that emits intermittent pulses with a low amperage.
To create an electric fence for animals you need: a Gemi energiser - 100% Made in Italy - for fences that carries the current to the fence, an electrified conductor wire for the fence and insulators for electrified fences screwed on the posts to hold the wire.
Grounding is a fundamental thing for the functionality of the electric fence for animals, so it is recommended to do it correctly. To have the total discharge of current by the energiser, it is necessary to make the grounding by inserting 3 galvanized poles of 1 meter in the ground.
They must be positioned 3 meters apart, 80 cm in the wet ground and 20 cm outside, and then connect them with the yellow cable.
Together with the electric fence, we supply only 1 meter of cable that must be connected to the first pole. It is recommended to do it where there is the presence of vegetation, therefore a moist soil. Arid soil is not conductive. According to the tests carried out, placing 3 poles in any type of terrain, there will be no problem with functionality.
If you put only one stake, the power of the current felt will be less than its range and the animals will be able to cross the fence.
For a B12 energiser it is sufficient to use a 12V 40Ah car battery. The autonomy, if there is no dispersion in the electric fence, is about 10/12 days. Otherwise it lasts less.
If the current is far from the electric fence, for your Gemi energiser - 100% Made in Italy -, we have the high-voltage crossing cable that can work on the surface or underground, without discharging.
With this cable it is possible to carry current on the fence, without any dispersion.
The cable for electric fences can also be used to join two fences, then connect one end to a first fence and the other end to a second fence, when there is little distance between one fence and another.
Without going around the dead circle of the insulator for electric fences, otherwise dispersion is created. Gemi electric fence insulators have been designed for this purpose.
To check if there is current on the electric fence for animals, just bring the tip of a screwdriver with an insulated handle a few mm away from the fence wire.
The moment you hear a ticking, it means that there is current on the electric fence.
An energizer cannot be kept outdoors. It must be kept indoors to prevent damage from the weather. In order to discharge all its current, it must be earthed by inserting 3 galvanized 1 meter stakes into the ground. They must be placed 3 m apart, 80 cm in the ground (wet) and 20 cm outside, and then connected with the yellow-green cable.
The device has a red positive cable at its output which is connected to the fence and a yellow-green cable which is connected to the first ground stake.
Never connect two electrifiers to the same wire, as the two impulses may cancel each other out, causing problems. You can connect two electrifiers to the same fence, but keep them on two separate lines of wire.
