The conductor you reel out matters more than people think. Here is how polywire, polybraid, and poly rope differ — and which to grab for the job. Trying to choose a fence type altogether? This guide zooms in on the temporary conductor itself.
They are not the same wire
All three are plastic filaments woven with thin metal conductors so they carry a pulse while staying light enough to reel. The differences — how many metal strands, how visible, how tough — decide how far the power carries and how long the fence lasts.
The three conductors
| Polywire | Polybraid | Poly rope / tape | |
|---|---|---|---|
| Build | Thin twisted filament | Braided, more metal strands | Thick rope or wide tape |
| Conductivity | Lowest (few strands) | High (more strands) | High (rope); tape varies |
| Visibility | Low | Medium | Highest |
| Durability | Lowest | High | High (rope) |
| Best for | Short runs, cheap & light | Daily moves, all-around | Horses, high-visibility |
The spec that actually matters: metal strands
A conductor’s resistance is set by how many metal strands it has and what metal they are (mixed copper/stainless beats all-stainless). More, better strands = less voltage lost over distance. Cheap 3-strand polywire bleeds power fast and will read weak at the far end of a long run; quality 6–9 strand polybraid carries a hard hit much farther. For long temporary runs, conductivity beats price.
Match the conductor to the job
- Short daily breaks, light use: polywire is cheap, light, and fine over short distances.
- Everyday rotational grazing: polybraid is the all-rounder — visible enough, conductive enough, and durable enough for daily reeling. This is what most graziers should default to.
- Horses: visibility prevents wrecks — use poly rope or wide tape so horses see and respect the fence. More in electric fence for horses.
- Long runs: pick the highest strand count you can, or switch to steel high-tensile for permanent.
Reels and tension
Whatever you choose, a geared reel makes deploying and winding fast and keeps the conductor from tangling. Keep it tensioned (sagging conductor shorts on grass and looks sloppy), and avoid kinks — broken metal strands inside the plastic are invisible and quietly kill conductivity.
Care that extends life
- Wind it up between uses — UV and weather age idle conductor.
- Avoid knots; use proper connectors and buckles so metal strands stay joined.
- Watch for fraying; a frayed conductor loses both strength and conductivity.
Frequently asked questions
Polywire or polybraid — which is better?
Polybraid for almost everything: more metal strands (better conductivity), more visible, and more durable. Polywire wins only on price and weight for short runs.
What carries power the farthest?
The conductor with the most and best metal strands — quality polybraid or poly rope — or steel high-tensile for permanent fence. Cheap polywire fades fastest over distance.
What is best for horses?
High-visibility poly rope or wide tape, so horses see the fence and do not run through it.
Why does my temporary fence read low at the far end?
Usually a low-strand conductor, a kink that broke the metal strands, or a short on vegetation. Step up to better polybraid and keep it tensioned.
Bottom line
Default to polybraid for daily grazing, polywire only for short cheap runs, and rope or tape for horses. Count the metal strands, keep it tensioned and tangle-free, and reel it up between moves. Pair it with a good geared reel and the right energizer.
