Modern-day insulators
Strainrite fencing Systems says it has developed the Joule Shield wooden post claw insulator to address the limitations inherent in older insulators.
The standard has a specially moulded pigtail loop insulator with no internal wire, thereby eliminating the risk of electrical shorts that ocurr when insulators wear through.
Made from UV stabilised, wear resistant polymer to withstand harsh New Zealand conditions, the standard’s poly-wire/tape makes them easy to install and reduces the risk of wire/tape ‘falling out’ a fence line is being moved.
The moulded profile of the loop has no sharp edges, so minimises any chafing, and the narrow tape opening prevents the annoyance of heads ‘interlocking’ – common with standard designs, the company says.
Available in 6mm light, 6mm long and 7mm heavy-duty sizes, all the standards have galvanised spring steel shafts and a galvanised pressed steel foot, said to be stronger than mild steel or plastic.
Strainrite general manager Brian Collins says “the concept of a loop top pigtail has been around for many years.
“We’ve listened to users around the country to come up with this new design and we see the Tangle Free offering giving more choice to farmers.”
