AS Pin Type Insulators

Standard: AS 4899-2007, IEC60383

Voltage:0.4-36kV

As the name suggests, the pin insulator is secured to the cross-arm on the pole. There is a groove on the top of the insulator to hold the conductor. The conductor passes through groove and is bound by the same material as the conductor.
The live conductor is place on the top of the insulator and the bottom of the insulator in connected to earth. The insulator has to withstand the potential stress between conductor and earth. When insulator is wet, its outer surface becomes almost conducting. Hence the flash over distance of insulator is decreased. The electrical insulator is designed such that the decrease of flash over distance is minimum when the insulator is wet. That is why the upper most petticoat of a pin insulator has umbrella type designed so that it can protect the rest lower part of the insulator from rain. The upper surface of top most petticoat is inclined as less as possible to maintain maximum flash over voltage during raining.
