Pin Type Insulator 56 Series High -Voltage Pin Type
Product Detail
56 Series High -Voltage Pin Type
Standard: ANSI C29.1, ANSI C29.6
Voltage:11-36kV
As the name suggests, the 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.
