Here are some details about these insulators:
1.Insulator Type: These insulators come in two types: Plain and Radio Freed.
2.Voltage Rating: The voltage rating for these insulators is 7.2 kV.
3.Leakage Distance: The leakage distance is 4 inches (102 mm) for some models and 5 inches (127 mm) for others.
4.Dry Arcing Distance: The dry arcing distance varies between 2-1/4 inches (57 mm) and 3-3/8 inches (86 mm).
5.Average Flashover Voltage: The average flashover voltage also varies depending on whether the conditions are dry or wet, and whether the impulse is low-frequency or critical.
