Review RateThey are better
I think they changed their formula because I bought these in 2019 and they were junk. The company sent me replacements and they work! We have 15 acres of fencing that burned in the Paradise Ca fire so we had to replace most of the insulators after they were melted. I am so happy to have them work now. They no longer snap when I put them on the post. Thank you Zareba!
Review RateThese are junk
I bought a ton of the yellow ones to run electric fence along a quarter mile of existing barbed wire. These are so flimsy, they just are not up to the task. They won't even stay on the posts well. I needed them so I used them, but in hindsight I should have sent them all back. Avoid these, they are junk. They are nothing like the old ones that held up well and lasted forever.Response From Zareba®Kathryn : Consumer Relations Representative

Review RateCan be carefully fitted
Broke 4 of the first 5 putting them on before I figured out that you can CAREFULLY use a large flat bladed screwdriver to pry them around the 'T' of the post - just pry the insulator end the bare minimum needed and push it and the screwdriver over the edge of the 'T'. Put the remaining 20 on with no problem along with most of another bag. They fit better on new posts than they do on old ones. Some of the old ones are thicker and some have slightly longer 'T's. I did get them on all of the posts eventually.
Waste of time and money. Dont fit without breaking.Response From Zareba®Lauren : Consumer Relations Representative

Review RateHot water, no more breaking
I had trouble breaking em, feedstore guy said nobody else has that problem. Oh well. I solved it by putting a bagful of insulators in a kitty litter bucket full of hot water. They float and they all but one went on. With the hinged lid snapped on, the bucket rolled along with me on my hand truck. In hot weather you might not need the hot water. So far as I see, the tab has to swing open to about 120• angle which is when they break. Helps a lot to shoehorn them open with a very slender blade like a butter knife or my ground-down slot tip screwdriver. If I'm not doing it right, somebody please tell me.
Review Ratethese insulators are junk. I do not want emails from you either
American Farm Works...Made in China. Our of a bag of 25, I broke 21. 4 insulators are on my tposts. Inly 2 are on all the way. Awful product. Save your money and sont but themResponse From Zareba®Jennifer : Consumer Relations Representative

All About Insulators
Insulators prevent electrical shorts between the electrified wire and the fence posts. Good-quality insulators are critical to a properly functioning fence. Insulators are made from materials that do not conduct electricity, most commonly plastic or ceramic.
Plastic insulators are molded from polyethylene, polycarbonate, or nylon and are designed to hold electrified wire near a variety of posts without losing energy through the post.
There are several styles to choose from because the insulator must match both the type of wire and the type of fence post being used. Plastic insulators include round post insulators, T-post insulators, wood post insulators, corner post insulators, end post insulators, and chain link fence insulators.
Make sure the plastic insulator you choose is molded from heavy-duty, high-density polyethylene (or harder plastic) with UV inhibitors. This prevents arcing and provides long life with all-weather performance, protecting it from the weather. Most insulators are available in yellow, black and white.
Like plastic insulators, porcelain insulators are designed to hold electrified wire near fence posts without losing energy through the post.
When good porcelain insulators are properly installed they should be able to last the life of your fence.
Porcelain insulators are a very good choice for using with your high tensile fence system.
There are specialized insulators that are used for specific purposes. These can be summarized as follows:
- The tube clamp insulator attaches to standard tube-type stock to corral panels.
- Corner post insulators are designed to withstand fence line tension generated by the fence line pulling from the anchor point or changing directions.
- Corner insulators should also be used at fence line termination points.
- Corner post insulators are available in plastic and ceramic and accommodate steel wire, poly wire, poly tape and poly rope.
- Other insulators allow you to fasten electrified wire or poly products to posts and fences without losing energy through the post or fence.
- There are many specialty insulators to choose from:
- Chain Link
- Square Post
Insulators come in many styles to accommodate a wide variety of post and wire types. Choose the correct type of insulator for the type of post and wire you've selected.
If you're using a low impedance fence charger, use an insulator with greater arcing protection, which will prevent the current from jumping to the fence post.
Porcelain insulators may be more expensive than plastic insulators, but they are designed to last a long, long time, usually the lifetime of your fence!
Plastic insulators can be used with all types of wire (and high tension if it is designated for it), while porcelain insulators can be used with all wires except for poly tape.
Corner posts and end posts have to withstand greater tension than other posts along the fence line. Therefore, use insulators at these areas that are designed to withstand the extra stress.
In addition, keep insulators free from dirt, dust and cobwebs.
FAQs About Insulators
Q: Do I need insulators for my electric fence system?
A: Insulators allow you to fasten electric wires near the posts without losing energy through the posts and potentially shorting out your system, so yes, definitely use insulators to maintain the current throughout your fence line.
Q: Which type of insulator should I use?
A: There are several factors to consider when determining which type of insulator you want for your electric fence system. These factors include the type of fence post you will be using, and the type of wire you will be using. For corners and end posts you will need to know how much tension you plan to have on the wire.
Q: Is a porcelain insulator better than a plastic insulator?
A: Porcelain insulators are used with high tensile fences as well as standard electric fences. They will last the life time of the fence and add a nice look to the fence. Their only drawback is their initial cost: Porcelain insulators usually cost more than plastic insulators.
Insulators made from plastic are generally used for standard electric fences only, although there are some designed for use with a high tensile fence.More Insulator FAQs»
