Ever wondered why your electric fence seems to not work at certain points? Maybe you should check out your insulator. Electric fence insulators are those small rod-like materials that stick out of your fence posts to ensure that your electrical line is not cut. It functions as the connector of your wire and the support of your wire so that the electricity passing through it does not get grounded. There are different kinds of insulators. You have to pick the one that suits your need and that suits their function. There are thermal insulators designed to keep heat almost constant. Double glazed window and Styrofoam acts as insulators because air pockets reduce heat transfer. But for electric fences, you have to choose the design that matches the material of your fence and your electrical set up. It is common for electric fences to suddenly not work because of broken insulators. But you don't have to fret. Here are a few pointers that should be followed.
- First, you should go around the perimeter of the fence and inspect the entire line. You should be careful to check for chipped, cracked or broken insulators. Plastic insulators usually last only a few years because the material is not able to withstand the constant wear and tear. But the cheap selling price of plastic insulators makes them more attractive to the market. Ceramic and porcelain insulators are susceptible to breakage and cracking and chipping but last longer than plastic ones. Insulator variations have different properties. Silicon, with its semiconductor properties can act as either insulator or conductor. You have to make sure that you get the right insulator materials that can withstand the conditions in the area around which your fence stands.
- The next step is to disconnect all the power sources of the electric fence. This is to avoid accidents when replacing your insulators. Make sure you trace all the proper power sources and you switch off break switch. This is to ensure that you do not get electrocuted by your own fence. And as with dealing with any electrical repair, it is a must to turn of power sources.
- You now start removing your insulators one-by-one. If you see any damage in the wiring, make sure you repair these also. Remove the wire wrapped around the insulator slowly and remember to look for any damage to the fence post. Include these to the repair.
- After you have removed the old insulator, replace it with the new insulator. Make two or more coils to create a snug fit. But always keep in mind that there should be enough slack in the wire for you to reattach it to the fence post comfortably.
Keeping and maintaining an electrical fence post is not very difficult. You just have to check your set up from time to time. And of course, you have to choose the best insulator that can withstand the conditions in your property. This can mean longer time periods between maintenance and thus, less cost.
