Strain Insulators: High Tensile Strength & Secure Hold
Keep your electric fence reliably under tension. Sturdy strain insulators safely absorb the forces at fence starts and corners and prevent sagging.
Strain Insulators: Stable Fastenings for High Fence Tension
At the corner points, at the beginning and end of an electric fence, the conductor material must be tensioned tightly so that the system does not sag. Normal line insulators would not withstand this load in the long run. This is where strain insulators come into play. They are specifically designed to reliably absorb the permanent tensile force of wires and ropes.
Reliable Absorption of Tensile Forces
A very well-known model in this category is the so-called egg insulator. The conductor material and the fastening wire (to the post) are pulled through two separate, interlocking eyelets. This distributes the force optimally. The plastic is subjected to compression instead of tension, making the holder particularly break-resistant and durable.
Break-Resistant Materials for Long Durability
If an insulator tears at the beginning of the fence, the entire line loses its tension. Strain insulators are therefore made of highly resilient, UV-stable plastics or resistant porcelain. They hold the conductor material firmly in place and reliably insulate the high electrical voltage from the corner or end post.
Frequently Asked Questions about Strain Insulators
Which conductor materials are strain insulators suitable for?
They are ideal for steel wire, polywire, and pasture ropes. For wide electric fence tapes, there are special tape strain insulators that fix the material flatly without compressing it.
How do I attach a strain insulator to the wooden post?
You need a short piece of wire or a wire rope. This is pulled through one side of the insulator and tied firmly around the wooden post. The actual conductor material is then pulled through the other side of the insulator and tensioned.
When should I use porcelain insulators?
Porcelain is particularly weather-resistant, heat-resistant, and durable. For permanent fences with very tightly tensioned steel wire and high mechanical stress, porcelain strain insulators are an excellent, long-lasting choice.
Heavy-Duty Fastenings for Fence Ends
For an electric fence to maintain its guarding safety, the conductor material must be well tensioned. This creates high forces at the corner and end posts. Strain insulators have been specially developed for these requirements. They safely absorb the mechanical pull of wires, polywire, and ropes without breaking or bending.
In our range, you will find proven egg insulators made of plastic, special tensioners for fence tapes, and very durable models made of porcelain. With these fastenings, you guarantee a stable, taut, and low-maintenance fence system that easily withstands wind and weather.
