Description
JVA Strainer Insulators key features
- High Strain Use: Engineered to withstand the tension from high-strain fence wires.
- UV Stabilized: Made with superior UV stabilization for a long service life, even in outdoor conditions.
- Wire Grip: Features deep grooves to securely hold fence wire in place, preventing twisting and slippage.
- Arcing Prevention: A long leakage path is incorporated into the design to prevent electrical arcing, which can damage the insulator and reduce the fence’s effectiveness.
- Versatility: Compatible with most sizes and types of electric fence wire, including polywire, polyrope, and polybraid.
- Installation: Can be directly attached to wooden posts or other strainer structures.
Function in an Electric Fence
Strain insulators perform two crucial functions:
-
Maintain Wire Tension:
They are used to apply and maintain tension on the fence wires, which is vital for the overall effectiveness and durability of the electric fence.
-
Electrical Isolation:
By being electrically non-conductive, they prevent the fence’s electrical current from flowing into the strainer posts or the ground, ensuring the fence’s ability to deliver a shock to animals.
Typical Use Cases
JVA strainer insulators are commonly found in:
-
End and Corner Posts:
To secure and tension the ends of fence lines or to manage the angled wires at corners.
- High-Tensile Fencing: Ideal for applications requiring high tension, such as some agricultural or perimeter fencing
