Electric Fence Wire for Reliable, Effective Electric Fencing

Choosing the Right Electric Fence Wire

The best conductor depends on the animals being contained, fence length and whether your boundary is temporary, semi-permanent or permanent. Conductivity matters particularly over longer distances: electrical resistance increases the voltage drop along a fence, so choosing an appropriate conductor and making sound connections helps the energiser deliver an effective pulse throughout the system.

• Consider galvanised or suitable metal wire where high conductivity, durability and a more permanent installation are priorities.
• For horses, visibility is particularly important. Wider electric fence tape can provide a more obvious visual boundary than thin wire where appropriate.
• Match your conductor to a suitable battery fence energiser, mains fence energiser or solar fence energiser, taking account of fence length, vegetation and expected load.
• Use purpose-designed electric fence insulators to prevent the live conductor contacting posts and losing energy to earth.
• For temporary divisions and strip grazing, an electric fence reel makes setting out, moving and storing suitable conductors considerably easier.

Technical Specifications and Electric Fence Care

A successful fence is a complete electrical circuit, not simply a powerful energiser connected to wire. Conductor resistance, connections, earthing, insulation, vegetation and overall fence length can all influence performance. When comparing electric fence wire, check the manufacturer's resistance or conductivity specification where available: lower electrical resistance generally allows energy to travel more efficiently over longer runs.

Correct tension matters too. Wire should be securely supported without excessive tension that places unnecessary load on posts, insulators or joints. Suitable wire tensioners and strainers can help maintain a consistent fence line. Inspect connections regularly for corrosion, looseness or damage and keep vegetation from making prolonged contact with live conductors, as heavy growth can drain energy from the fence.

Expert tip: when dismantling temporary fencing, wind compatible wire or tape evenly onto a reel rather than coiling it loosely. This reduces tangles, kinks and damaged conductor strands, making the fence quicker to reinstall and easier to inspect before its next use.

Frequently Asked Questions

What is the best wire to use for an electric fence?

The best choice depends on fence length, livestock and whether the installation is temporary or permanent. Conductivity, electrical resistance, strength and visibility should all be considered rather than choosing on wire thickness alone.

Can you use electric fence wire for horses?

Yes, but visibility and safety are important. Highly visible electric tape, rope or specialist horse fencing may be preferable to thin wire for some equestrian boundaries, particularly where the electric fence forms the main visual barrier.

Why is my electric fence losing power?

Common causes include vegetation touching the conductor, poor earthing, damaged insulators, corroded connections, unsuitable wire or excessive resistance over long fence runs. Test the system systematically to locate the source of the voltage drop.
