An electric security fence can be an extremely effective intruder deterrent but in order to deliver the right performance, the system must maintain as high a voltage on the fence wires as possible – and in all environmental conditions. Our electric fence insulators have been specifically designed with these factors in mind. They maximise the fence voltage and prevent losses caused by insulator capacitance and tracking. The insulators are resistant to Ultra Violet light and are coloured black for maximum UV resistance.
We offer 2 types of insulators – Electro-Fence™ intermediate insulators and Electro-Fence™ end/corner insulators.
Electric Fence Insulators: Intermediate (Donut Insulators)
These intermediate electric fence insulators are sometimes referred to as Donut insulators. This is because of their circular shape with the hole through which the wire passes. A simple but clever design and a great culinary analogy that makes them easy to remember!
EF260 – Electro-Fence™ Intermediate Insulator
Our Electro-Fence™ intermediate insulators are made from high density polyethylene and have been designed for minimum contact with the fence wires to keeping capacitive losses to a minimum. They are self-cleaning and are fitted with a water barrier to prevent tracking. These insulators are attached to the Electro-Fence™ post with a stainless steel split pin or alternatively with a blind pop rivet.
This next photograph below shows our intermediate (donut) insulators installed on an electric fence where climatic conditions can be harsh. Proof of their special design for performance in all environmental conditions.

End or Corner Fence Insulators
Essentially, end or corner insulators are double U Channel insulators which, by virtue of the way the wire is attached, allow the creation of a corner on the inside of the electric fence.
EF270 – Electro-Fence™ End/Corner Insulator
Our corner/end insulators are made from high density polyethylene and have been designed to allow maximum spacing between live and earth in order to minimise voltage loss on the electric fence due to tracking. There is no overlap of live and earth wires and a water barrier separates the two sides.
How do you install electric fence insulators?
For anyone interested in how the installation of insulators is done on an electric fence system, we have published our own photo guide to electric fence insulator installation. The photos you will see were taken during an installation by one of our approved electric fence installers at a high security site.
