Steps to build a safe, strong system
An electric fence works by sending a short, high-voltage pulse through the wire on a very brief duty cycle — enough to deliver a strong deterrent shock without being lethal. Building one properly starts with the earth ground, not the wire: the pulse only completes its circuit, and delivers a proper shock, if the system has a solid, low-resistance ground connection back to the energiser.A weak or corroded ground rod is the single most common reason an “installed” electric fence doesn’t actually deter anything — the wire is live, but the shock is too weak to notice.
Wire types compared
● High-tensile wire — holds tension over long spans and resists sagging over years; the standard choice for permanent perimeter runs.
● Tension wire — easier to handle and work with on shorter runs, though it needs more frequent tightening than high-tensile.
● Polytape — a woven tape with fine wire strands running through it, used where the fence line needs to be clearly visible as well as electrified.
The right setup depends on the run length and what you’re deterring — livestock, intruders, or both — as much as it depends on budget. |
