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.
FAQs about Insulators
Do I need insulators for my electric fence system?
A: Insulators allow you to fasten electric wires near the posts without losing energy through the posts and potentially shorting out your system, so yes, definitely use insulators to maintain the current throughout your fence line.
A: There are several factors to consider when determining which type of insulator you want for your electric fence system. These factors include the type of fence post you will be using, and the type of wire you will be using. For corners and end posts you will need to know how much tension you plan to have on the wire.
Is a porcelain insulator better than a plastic insulator?
A: Porcelain insulators are used with high tensile fences as well as standard electric fences. They will last the life time of the fence and add a nice look to the fence. Their only drawback is their initial cost: Porcelain insulators usually cost more than plastic insulators.
Insulators made from plastic are generally used for standard electric fences only, although there are some designed for use with a high tensile fence.
