All About Fence Insulators

Insulators are designed to fasten electrified wire to posts without losing energy through the post. They come in either plastic or porcelain and should be purchased according to the type of post and the type of wire being used.

Using a good insulator is important to maintain the performance of your fence.

Expert Tips

Insulators come in many styles to accommodate a wide variety of post and wire types. Choose the correct type of insulator for the type of post and wire you've selected.

If you're using a low impedance fence charger, use an insulator with greater arcing protection, which will prevent the current from jumping to the fence post.

Porcelain insulators may be more expensive than plastic insulators, but they are designed to last a long, long time, usually the lifetime of your fence!

Plastic insulators can be used with all types of wire (and high tension if it is designated for it), while porcelain insulators can be used with all wires except for poly tape.

Corner posts and end posts have to withstand greater tension than other posts along the fence line. Therefore, use insulators at these areas that are designed to withstand the extra stress.

In addition, keep insulators free from dirt, dust and cobwebs.
