ANSI 55-1 55-2 55-3 55-4 55-5 Ceramic Porcelain Pin Type Insulator

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.ANSI Class/StandardANSI 55-3Dimensions(ln)Pin Hole Diameter - Inchs1Pin Length5Leakage Distance7Dry Arcing Distance4-1/2Mechanical Values(kV)Cantilever Strength(lbs)2500lbsElectrical Values(kV)Typical Voltage Class11.5kVLow frequency flashoverDry55kVWet30kVImpluse flashover voltagePositive90kVNegative110kVLow frequency puncture voltage90kVRadio influence voltageTest voltage to ground10kVMax.
