The primary role for insulators for permenant fencing is to securely hold the fence line without power leaking from post to ground. A well designed insulator will hold the line securely so that it will not wear the tape, rope or wire when buffeted around by the elements or will allow the line to freely pass through without the impedance of sharp edges.

Permanent fence post insulators

The best grade polymers are utilised to create Gallagher's heavy duty plastic insulators, which are UV stabilised for durability, toughness, and sun resistance.

For places with a significant fire danger, porcelain insulators are fire-resistant and the best choice. Your choice of wire type and post type for your electric fence will determine the sort of insulators you need. To figure out how many insulators you need: Determine how many insulators are required by multiplying the number of fence posts by the number of strands.

Use insulators designed particularly to manage the additional wire strain at corners and ends. To figure out how many corner/end post insulators you need: calculate the number of corner/end posts x the number of wire strands = number of corner/end post insulators needed.

Types of Permanent fence post insulators

A variety of insulators are available from Gallagher to secure electric fence wires to the selected post.

Wood Post Insulators

The Claw Insulator offers a robust, long-lasting attachment method with a substantial protection. The wire can also be temporarily disconnected from the fence while under stress thanks to Pinlock insulator devices. When temporary vehicle access requires the lowering of wires, for instance. Insulators are also offered for use with other horse fence materials, such as tape and wire. All of these are fastened to the post with flat-head nails, screws, or staples.

Steel Post Insulators

Quality double pinlock insulators for holding electrical wires to steel t-posts and y-posts are produced by Gallagher, together with a topper cap for fastening a top-mounted tape or wire.

Fiberglass Clips 

Metal clips are used to secure cables to fibreglass poles.

Insulated Line Post Clips

Utilizing specially created insulator clips, attach wires or tape to Gallagher Insulated Line Posts.

What are Electric fence insulators for wooden posts?

Electric fence insulators for wooden posts are designed to hold the electric fence wire away from the wooden post, preventing the current from short-circuiting and grounding out. The insulators are made of non-conductive materials such as plastic or ceramic, and they come in various shapes and sizes to fit different types of wooden posts.

The advantages of Electric fence insulators for wooden posts

The advantages of using electric fence insulators for wooden posts are:

  1. Increased effectiveness: Electric fence insulators ensure that the fence wire is not grounded out, which maximizes the effectiveness of the electric fence in deterring animals.

  2. Reduced risk of fire: Insulators reduce the risk of fire caused by the electric fence wire coming into contact with the wooden post.

  3. Durability: Insulators are made of non-conductive materials that are resistant to weather and UV rays, ensuring that they last a long time.

  4. Versatility: Insulators come in various shapes and sizes, making it possible to use them with different types of wooden posts.

How do Electric fence insulators for wooden posts work?

Electric fence insulators for wooden posts work by creating a gap between the electric fence wire and the wooden post, preventing the current from flowing directly into the post and grounding out. The insulator is attached to the post using screws or nails, and the electric fence wire is threaded through the insulator, which holds it in place.

Tips for determining the best Electric fence insulators for wooden posts

When determining the best electric fence insulators for wooden posts for your needs, consider the following factors:

  1. Post type: Make sure the insulators you choose are compatible with the type of wooden posts you have.

  2. Fence wire type: Insulators are designed for specific types of fence wire, so make sure the insulators you choose are compatible with your wire.

  3. Climate: Choose insulators that are suitable for the climate in your area.

  4. Fence design: Consider the design of your electric fence and choose insulators that will work with your particular fence design.

How do you install Electric fence insulators for wooden posts

To install electric fence insulators for wooden posts, follow these steps:

  1. Choose the correct insulator for your wooden post and fence wire.

  2. Pre-drill holes into the wooden post at the desired height and spacing for the insulators.
