Pin Post Insulator Designs

The pin post insulator is a unique design, combining the advantages of the line post insulator with with the advantages of the pin type insulator. These insulators offer an economical alternative to line post insulators (fitting on the same mounting pins as pin type insulators) while providing the improved operating characteristics of line posts – more rugged construction, improved resistance to lightning impulse damage, and standard ANSI threaded pin holes. The insulators are designed with standard ANSI neck dimensions to enable use of existing pre formed (wrap lock) ties.
