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.

Insulators
Insulators keep the electric fence conductor away from the post and prevent current from leaking to earth — a single faulty insulator can halve the voltage reaching the far end of your fence. Gemi Elettronica patented its insulator design in 2019 after years of field testing, producing a range that fits wooden posts, iron posts, T-bar posts and pickets without requiring specialist tools. Gemi insulators are sold in packs sized for typical fence runs. Order direct from the manufacturer for factory pricing, no minimum order and UK delivery in 24–48h with full tracking included in the standard shipping rate.
Insulators for wooden posts
Gemi's ring insulators for wooden posts are larger than the European market average, giving a firmer grip on both polywire and tape. The windproof clip prevents the conductor from lifting off in gusts, eliminating the intermittent contacts that drain energiser output. The UV-stabilised polymer retains mechanical strength and insulation resistance after years of outdoor exposure in all climates.
Insulators for iron and metal posts
Two models cover the most common metal post profiles — round tube and flat T-bar — snapping securely without drilling or additional fixings. The polymer compound is selected for resistance to galvanic corrosion caused by prolonged contact with steel in wet conditions, ensuring the insulator remains firmly in place season after season.
CE certified — patented 2019
All Gemi insulators carry CE certification. The 2019 patent protects the windproof retention system that distinguishes Gemi insulators from conventional designs. Compatible with Gemi polywire in all cross-sections, with tape up to 40 mm and with braided rope conductors.
Fast installation, no tools required
Each insulator clicks onto the post and locks the conductor in under ten seconds. Large-scale installations covering hundreds of posts can be completed in a fraction of the time compared with screw-fix alternatives. UK delivery in 24–48h direct from the Gemi factory.
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.
