The Pole Top Insulator Pin supports pin-type insulators in electrical distribution pole-top installations, accommodating insulator threads with 1-inch or 1-3/8-inch diameters. The flange can mount either against or away from the pole, providing installation flexibility. This design eliminates the need for lead threads, addressing worker safety and environmental disposal concerns while ensuring secure insulator mounting for reliable electrical isolation and mechanical support.
Constructed from ductile iron with a vinyl coating over the thread area, the pin combines durability with enhanced corrosion resistance. It delivers a minimum ultimate strength of 2,000 pounds (8.9 kilonewtons), withstanding significant mechanical loads to maintain insulator stability and alignment during operation under environmental stressors.
The pin features a firm, resilient fit that enhances insulator retention and groove alignment, improving installation outcomes. A slotted lower mounting hole simplifies bolt alignment, reducing setup time and facilitating efficient installation. These attributes contribute to overall system reliability and ease of maintenance in overhead distribution lines.
Compliant with American National Standards Institute (ANSI) performance and dimensional specifications, the Pole Top Insulator Pin meets industry standards for safety and interoperability across utility environments, ensuring consistent application in infrastructure projects.
