The purpose of insulators is to insulate the conducting material from the post and the ground. They prevent a flow of electricity between the fence and the soil and ensure that there is always a sufficiently high voltage in the fence conducting material.

What should I be aware of when choosing electric fence insulators?

The larger the insulator, the better its insulating properties.

The use of insulators with drip-off points is recommended. These drip-off points are located between the insulator's eyelets and screw and drain away moisture. This improves the insulating properties of the insulator in wet conditions. (You should therefore never wrap the wire around the drip-off point. This can result is jumping sparks!) If you need to tension the wire, it is better to use a special insulator such as the Spannfix for polywire Item no. 44336)

Insulators are divided into holding insulators and guiding insulators.

Holding insulators go in the direction of the conducting materials, tensioning and holding it. They are mounted to corner posts and tensioning posts.

Guide insulators hold the conducting material at the required height and are mounted to stretching posts. To keep the necessary flexibility in the fence, you must ensure to only run the conducting material through the guide insulators. The guide insulators are not intended to tension or grip the material. Wrapping the material around the insulator would remove the required elasticity from the fence. This elasticity is necessary to prevent the conducting material from tearing when, for example, an animal leans against the fence. The type of insulator you should choose depends entirely on your individual circumstances. The type of conducting material to use and the posts dictates which insulators are needed.

Here are a few of the features that differentiate electric fence insulators:

One of the differences is the way the insulators are mounted. Many insulators are attached by screws, but there also insulators that are attached with clamps, clips or nails.

Insulators can be screwed to wooden posts using wood threads. Metric threads should be used for attaching insulators to metal posts.

There are also special insulators for fixing to round posts, mesh wire fences and stanchion fences.

If you would like to run the conducting material at a particular distance from posts, you need to use a long shaft insulator.

Ring insulators make good universal insulators. These are most used as guide insulators for polywire, wires, rope or tape. Their solid support makes them particular stable. Drip-off tips guide moisture away, thus increasing their insulating properties.

Special insulators are available for electric ropes and tapes.

Corner insulators are used to guide the conducting material around corners. They possess exceptionally good stability. The conducting material is also attached to corner insulators at the start and end of the fence. With some corner insulators you need an additional connector (such as the "Super" corner insulator, Item no. 44812 with electric fence connector, Item no. 44684), other corner insulators such as the corner and tensioning insulator (e.g. Item no. 44632) do not require any additional connectors.

Gate handle insulators allow gate handles and conducting material to be attached on both sides. To connect polywire or rope use e.g. gate handle insulator, Item no. 44259.3, preferably with connections, Item no. 44426 or 44649 and 44650.

At we also specialise in special insulators for use in areas such as balconies, roofs or windowsills. We also have insulators designed especially for defense against martens.
(e.g. Item no.: 44332, 46010, 44347)

Have a browse through our product pages with Insulators to see the variety of insulators available.
You will see that there is a suitable insulator for virtually any application!
