Pin insulator

A Pin insulator consists of a non-conducting material such as Porcelain, Glass, Plastic, Polymer, or Wood that is formed into a shape that will isolate a wire from a physical support (or “pin”) on a telegraph, utility pole or other structure, provide a means to hold the insulator to the pin, and provide a means to secure the conductor to the insulator. By contrast to a strain insulator, the pin insulator is directly connected to the supporting pole. The earliest pin insulators predate the strain insulator and were deployed before about 1830. Pin insulators continue in production with manufacturers worldwide.
