Once an electric fence is properly installed, it can deliver a shock to animals that come into contact with the electrically charged wire. This happens because the electric current passes through the animal and completes the circuit by reaching the earth ground. Before constructing your fence, it is important to consider your specific fencing needs and seek advice from experts to ensure the best design.
A well-designed and sturdy fence is essential to withstand pressure from animals, snow, and wind. The fence charger, also known as an energizer or fence controller, must have sufficient power to effectively control the animals and cover the entire length of the fence.
Proper grounding is crucial for the electric fence system, as the earth completes the circuit. In areas with poor soil or grounding conditions, a two-wire system can be used, with one wire carrying the electric charge and the other acting as the earth ground. This system is employed when alternating "hot" and ground wires are installed.
To maintain the effectiveness of the electric charge, it is important to prevent the electrically charged wire from coming into contact with shrubs, tall grass, fence posts, nails, or any other conductive objects on a continuous basis.
Regardless of the wiring system used, it is always necessary to use ground rod(s) and connect them to the charger's ground terminal.
Choosing the right fence charger is vital for the successful containment or exclusion of animals. It is recommended to follow a simple process, such as the one explained by experts at Lydite® Systems, to ensure you select a charger that suits your specific requirements.
Please note that it is important to comply with local laws and regulations when installing electric fences to ensure the safety of both animals and humans.
When it comes to electric shocks, both volts and joules contribute to the effect on an animal. Let's examine the distinctions between the two:
Volts: Volts represent the electrical potential difference, which propels the electric current through an animal's skin or hide and affects its nerves. To deliver an effective shock, it is necessary to supply enough amperes to the fence to maintain a minimum of 3,000 volts. If the fence has a low load, such as stainless-steel wires in twine, a small conductor (wire) can be used since minimal amperage is required. A low-power charger that maintains the desired voltage can effectively control the fence.
Joules: Joules, on the other hand, measure the energy required to carry the electric current along the fence and through any load. Think of joules as the power necessary to facilitate the current flow. The length of the fence, its age, and construction determine the required joules. As a general guideline, it is recommended to have one joule per mile of fence. It's important to note that having a higher joule rating is preferable until the point of induction, where the voltage becomes too high and can power gates and neutral wires. Induction may occur when the voltage approaches 7,000 volts.
In situations involving underground cables at gates or from the charger, or when there is significant conductive growth on the fence, it is logical to use high-power chargers and thicker wire, such as 12½ gauge. For very long lines of single wire leading to areas with heavy loads, it is advisable to use aluminum-clad, high-tensile steel wire. It's worth mentioning that most of the power from a high-power charger is utilized to overcome shorts, inductance, and capacitance on the fence, rather than directly affecting the animal.
Determining joule ratings for chargers can be a complex process, and different companies may employ various methods, making it challenging to compare chargers accurately. There are multiple variables and calculation approaches involved in determining joules, and even voltage measurements at different resistance levels across the terminal may not provide a comprehensive understanding, as they do not account for the pulse's duration. While the size and voltage of capacitors can offer some insight into stored power, the efficiency of power transfer to and through the output transformer can still vary.
In summary, both volts and joules contribute to the impact of an electric shock on an animal. Volts determine the force that propels the current through the animal, while joules represent the energy required to carry the current along the fence and any associated load.
Timeless Fence System offers versatility that other fencing products lack
Made from plastic Materials
We use Rigid PVC that is also used in vinyl window frames to make the Timeless Fence System. This material is ground and extruded into our posts. It is weatherable and UV protected. The life expectancy is 40+ years. Timeless Fence Posts are an eco-friendly and cost-effective alternative to traditional steel t-posts and wood posts widely used in construction, farming, landscaping, and erosion control.
Self Insulating
Ideal for installing electric wire – no insulators needed. High-Tensile wire and electric braid can be threaded directly through the post for an extremely strong, virtually maintenance-free fence.
Easy to Install
Farmers and ranchers across the U.S.A. and around the world are finding that Timeless Fencing is easy to install. Posts are pre-drilled every three inches to greatly reduce cost and installation time.
Strong Yet Flexible
Timeless Fence posts absorb impact and bounce back, making it all but impossible to break under normal use. Robust design withstands harsh weather and is strong enough to hold barbed wire and woven wire. NEVER Rusts or Rots: Replace wood and steel posts once with the Timeless Fence System and use your extra time on productive tasks – not fence repair.
Lasting Beauty
You’ll be proud to see this good looking fence along your property. The satin-like finish on these posts maintains its new look for many years.
