The purpose of an insulator is to keep the wire from touching the post or other grounded items. Electric fence insulators can be made of plastic or porcelain and come in several styles because the insulator must match both the type of fence post and the type of wire being used.
Some insulators connect to wood posts, T-posts, round posts, U-Posts, chain link posts and wire. The other end of the insulator connects to wire, Polywire, Polyrope and Polytape.
Electric Fence Insulators are usually made of plastic or porcelain, each having its own advantages:
Plastic Insulators- Plastic post insulators are nailed to the post and are molded from polyethylene often with UV inhibitors to protect it from the weather.
Fi-Shock® post insulators are nailed to the post and are molded from high-density polyethylene with UV inhibitors for all-weather performance and durability.
Only Fi-Shock® wood post polyethylene insulators come with specialized long ribbed nails or double-headed nails for easy removal to relocate the insulator, if desired.
Porcelain Insulators- These insulators are often more expensive per unit than plastic insulators but they are designed to last a lifetime under normal conditions.
Fi-Shock® porcelain insulators are produced from specially formulated electrical porcelain for superior insulation and strength. Fi-Shock® porcelain insulators have the highest insulating properties for use in electric fencing and do not break down due to damage from the sun.
When the Fi-Shock® porcelain insulators are properly installed, they will last the life of your fence. Porcelain insulators can handle any size fence wire including wire, polywire and polyrope.
Using a good insulator is important to maintaining optimum performance of your electric fence system.
Fi-Shock® provides all the insulators that you will need for most electric fence projects. When used properly, they will last for years or a lifetime.
