Creepage distance of disc insulator

The size of Creepage distance of disc insulator is very important for using insulator in pollution and wet encironment. The disc insulator is made from composite, also called composite suspension insulators.

disc insulator

These disc insulators ensure maximum creepage path due to their distinctive geometrical configuration.

What is the creepage distance of disc insulator?
Creepage distance of disc insulator or other composite insulators is the shortest path between two conductive parts (or between a conductive part and the bounding surface of the equipment) measured along the surface of the insulation.

Creepage distance of disc insulator usage
A proper and adequate creepage distance protects against tracking, a process that produces a partially conducting path of localized deterioration on the surface of an insulating material as a result of the electric discharges on or close to an insulation surface.

Inspecting creepage distance of disc insulator depends on two major factors: the comparative tracking index of the material and the degree of pollution in the environment.
