An insulator's primary role is to securely hold the fence line without power leaking from post to ground. Insulators come in a range of different shapes and sizes in order to provide specific functions in your electric fence system. Ring insulators and tape insulators are made of a UV-resistant plastic, ensuring a long service life. They are also ideal for insulating an electric fence, as they are particularly weather-resistant. Off-set insulators hold the line away from the post giving extra clearance from hedges and walls. Off-sets are also useful for outwitting pests and predators. Installed at the base of a chicken run provides a 'scare' wire for the incoming predator or can be carefully placed to catch the sensitive ears of burrowing pests. Our wide range of ring insulators, strand insulators, tape insulators and screw-in aids ensure that we have the ideal product for your application and you can always shop with confidence at SPR Centre and expect fast delivery wherever you are in the UK.
