Electric fencing is a practical and flexible way to manage livestock, divide grazing areas and protect field boundaries. From permanent perimeter fencing to temporary paddocks for rotational grazing, choosing the right electric fence energiser, wire, posts and accessories is important for creating a reliable fencing system.
At Whyte Country Supplies, we stock a wide range of electric fencing and farm fencing supplies in Ireland, with equipment suitable for cattle, sheep, horses and other livestock.
How Does an Electric Fence Work?
An electric fencing system uses an energiser to send short electrical pulses along the fence line. When an animal touches the electrified wire, tape or rope while in contact with the ground, it receives a brief shock that encourages it to stay away from the fence.
A complete system generally consists of an electric fence energiser, conductive fencing material, insulators, posts and an effective earthing system.
The performance of the fence depends on the system being correctly installed and the various components being suitable for the length and type of fence being powered.
Choosing an Electric Fence Energiser
The energiser is at the heart of an electric fencing system. The right model will depend on factors including the length of the fence, number of fence lines, type of livestock and whether mains electricity is available.
Mains Electric Fence Energisers
A mains energiser is an excellent choice where a suitable power supply is available. These are particularly useful for permanent fencing installations and larger fencing systems.
Whyte Country Supplies stocks a selection of PEL mains fence energisers with different power outputs to suit different requirements.
Battery Electric Fence Energisers
Where mains electricity isn't readily available, a battery fence energiser provides a much more flexible option.
Battery-powered fencers are particularly useful for remote fields, temporary fencing and rotational grazing systems where the fence may need to be moved periodically.
Electric Fence Wire, Polywire, Polyrope or Polytape?
There are several different materials available for carrying the electrical pulse around a fence, and the best choice depends on how and where the fence will be used.
Electric fence wire is commonly used for longer-lasting and permanent installations where durability is particularly important.
Polywire and polyrope combine conductive strands with lightweight synthetic material, making them convenient for temporary fencing and paddock divisions.
Polytape is wider and highly visible, making it particularly useful where visibility of the fence line is important.
Our range includes PEL Enduro wire, polyrope and polytape in a choice of lengths and specifications.
Temporary & Rotational Grazing Fencing
Electric fencing is particularly useful for dividing fields into smaller grazing areas and managing rotational grazing.
A temporary system can typically be created using portable posts, polywire or tape and a fencing reel. The fence can then be moved as livestock progress through different grazing areas.
A good electric fence reel makes winding, storing and redeploying the fence line considerably easier.
Electric Fence Posts & Insulators
Posts provide the physical structure of the fence while insulators prevent the electrical current from escaping through the posts and into the ground.
The appropriate insulator depends on the type of post and whether you're using wire, rope or tape. Whyte Country Supplies stocks a range including tape insulators, rope insulators, clamp-on insulators and egg strainers, along with permanent and temporary fencing posts.
Earthing an Electric Fence
A good earthing system is essential to the performance of an electric fence.
Earth rods provide the return path needed for the electrical circuit to operate effectively when an animal touches the fence. Poor earthing can significantly reduce fence performance even when a powerful energiser is being used.
The number and arrangement of earth rods required will depend on the energiser and fencing installation, so the manufacturer's recommendations should always be followed.
How Do I Know If My Electric Fence Is Working Properly?
A fence tester or digital voltmeter allows you to check the voltage at different points along your fence.
Regular testing can help identify problems such as vegetation touching the fence, damaged conductors, poor connections or other faults that are reducing performance.
Whyte Country Supplies stocks dedicated electric fence testers and fault finders to make checking and troubleshooting a fencing system easier.
Frequently Asked Questions About Electric Fencing
What size electric fence energiser do I need?
This depends on the length and number of fence lines, vegetation levels, livestock being contained and overall fence conditions. Energiser manufacturers normally specify the size of fencing system each unit is designed to power.
Is a mains or battery fence energiser better?
Neither is universally better. Mains energisers are an excellent option for permanent systems where electricity is available, while battery energisers offer greater flexibility for remote fields and temporary fencing.
What is best for temporary electric fencing?
Portable posts combined with polywire, polyrope or tape and a reel make a practical system for temporary paddocks and rotational grazing.
Can electric fencing be used for cattle?
Yes. Electric fencing is widely used for cattle management, including permanent boundaries, temporary paddocks and rotational grazing systems.
Can electric fencing be used for sheep?
Yes, although sheep's wool can make effective contact more challenging than with cattle. Fence design, wire spacing and energiser performance therefore become particularly important.
Is electric fencing suitable for horses?
Electric fencing can be used for horses, with highly visible fencing materials such as tape often chosen to make the boundary easier for horses to see. The complete installation should always be designed with equine safety in mind.
How do I find a fault in an electric fence?
A fence tester or fault finder can be used to check voltage at different points along the fence. A significant voltage drop can help narrow down where a problem is located.
