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 or indicated by the clients.
The insulators are designed with standard neck 
dimensions to enable use of existing pre formed (wrap lock) ties.
In addition to the merits of Line Post Insulators, the pin post insulator have the following advantage:
Excellent anti-contamination performance
Excellent wet AC withstand voltage characteristics under contamination
High power arc resistively
Applied standard: ANSI C29.7 or other international standard
