Porcelain pin type insulator is mounted on a pin on the cross-arm on the pole. There is a groove on the upper end of the insulator. The conductor passes through this groove and is tied to the insulator with annealed wire of the same material as the conductor. Pin type insulators are used for transmission and distribution of electric power at voltages up to 33 kV. Beyond operating voltage of 33 kV, the pin type insulators become too bulky and hence uneconomical.
NJREC manufacturers three classes of pin type insulators. Low voltage pin types are manufactured and tested to the requirements of ANSI Standard C29.5, high voltage pin types to ANSI Standard C29.6, and special designs for use in areas of high contamination.
