Creepage distance of disc insulator is an important part of insulator technical data for using on what environment and flashover voltage.

How to calculate Creepage distance of disc insulator?
According to pollution level, creepage distance = the surface of insulator distance / maximum system voltage.

The minimum Creepage distance of disc insulator can be affected the voltage between the conductor assemblies. The affecting factors of Creepage distance of disc insulator
◆ Rated voltage
◆ Pollution level
◆ Insulator materials
◆ The shape of the surface
◆ Installation direction
◆ Withstand voltage duration

According to insulator application and definition, the Creepage distance of disc insulator should be always above the Clearance.
