Insulators are a vital part of electric fencing; they insulate the conductors from any connection to earth. Good quality insulators distinguish themselves with less resistance, which makes the electric fencing system more effective and energy efficient. There are special insulators for each type of conductor, wire, tape or rope.

When choosing the type of insulator, you should consider how long you want the enclosure to last. When it comes to insulators, you have a choice between nail insulators, ring or screw in insulators, W insulators or tape insulators. Nail insulators are cheaper than the ring or W versions but they are less durable. Ring insulators are the most commonly used type, because of their price/quality ratio. W insulators stand out for their quality and durability.
