Electric Fence

The choice of energizer

Irrespective of its mode of power supply, an effective energizer must release electric pulses suited to the terrain, the perimeter to be fenced and the types of animals present in order to maintain a minimum protection threshold throughout the year for any given point in the enclosure.



Power Energizer

Power supply mode
230 V mains energizers are recommended whenever the mains is available. However, with the increasingly widespread use of solar panels, gattery energizers are once again becoming a very advantageous alternative. Any further power needed can be supplied by an energizer that functions on a large 12 V wet cell battery (Perfo). For short fences or mobile applications, the facility offered by energizers on 9 V dry cell batteries (Compact) is perhaps to be preferred.



Terrain conditions
LACME's high tolerance low impedance technology desiccates vegetation that comes into contact with the fence from the first contact. If the segments that will be subject to extensive contact with vegetation are long, the energizer must be proportionally powerful.

Perimeter to be fenced
The electrical resistance of wires varies from one family of conductors to the next. Thus, the standard question "How many kilometers?" can only receive an answer based on the given "Energizer - Conducting wire" combination. With most conductive wires, an energizer of a few hundred millijoules is sufficient for enclosures from a few hundred meters to a few kilometers. An energizer offering a few Joules can electrify very large fences that may extend for several tens of kilometers.



Animals that are easy / difficult to contain
Certain animals may require larger power margins due to thick coats and/or hides that insulate them particularly well. This is for example the case with sheep, goats and wild animals when compared to cows, pigs or horses which are easier to contain.


Minimum containment thresholds
For an animal to receive a pulse that is sufficiently intense at a given point in the fence, this point must be subject to:
not only enough voltage to ensure that the fur and hide are penetrated,
but also enough power (in joules), so that the nervous system is sufficiently excited to produce a shock message in the brain.

According to certain scientific studies the minimum voltage thresholds necessary are 700 V for cattle and 2,000 V for sheep respectively. The minimum power threshold is less than 50 millijoules. From our experience, these very low minimum thresholds deserve a safety coefficient: by simplification, we recommend that in order to contain the majority of animals effectively all points of the enclosure must be maintained at above approximately 2,000 V and 100 millijoules.

Mains power supply


SECUR is synonymous with safety. What better name for this range which is the fruit of LACME's most recent innovations and offers the highest quality in terms of protection and safety. Just a few of the advantages: very high voltage, optimal power, Bipulstronic technology managed by microprocessor, compatibility with multi-transponders and Bip control, transfer socket, backlight panel, etc. Manufactured with tested components that are recognized for their great reliability, the SECUR range is a technological must for any demanding stockbreeder.

Yet another LACME exclusive!
Genuine guardian angels of the installation, up to 4 Sentinels can be installed at critical points on the fencing to keep the SECUR 2006 or 2006 ALT informed of the quality received at these points. Self-powered by the fence pulses, the do not require any battery or 230 V mains connection. They are installed on "posts" (fig. 1 - example of a long perimeter fence) or at the end of the line (fig. 2 - example of several separated enclosures). Provided that the enclosure is suitablye configured, they can detect gateways that are open, a wire cut in the air, deterioration of earth rod connections and even an insufficient conductivity of conductors orjunctions.
