Product Description
The pin ceramic insulator is mounted on a pin on the cross-arm on the pole. There is a groove on the upper end of the pin porcelain insulator. The conductor passes through this groove and is tied to the porcelain Pin Type Insulator with annealed wire of the same material as the conductor. Pin Insulator are used for transmission and distribution of communications, and electric power at voltages up to 33 kV. Beyond operating voltage of 33 kV, the pin type insulators become too bulky and hence uneconomical.
1.Higher Tracking and ARC Resistance
2.Higher Mechanical Strength
3.Satisfactory Leakage current
4.Very long life, made of inorganic materials and do not age
5.Possess high arc resistibility
