Porcelain Donut Insulator

An important part of your electric fence system, insulators are used to fasten electrified wires to your fence posts. An insulator’s job is to allow electricity to continue through the wire without any loss of energy to a post.

Made from materials that do not conduct electricity (mainly plastic or porcelain), a good quality, long life insulator is necessary for the performance, efficiency and longevity of your electric fence. If you are using a low impedance fence energizer you will also need insulators that provide excellent arcing protection due to the high energy output of these energizers.
