Electrically, the requirement for the minimum creepage distance is related to the voltage between the two conductive parts, the resistance index of the insulation material, and the pollution level of the environment where the electrical appliances are located.
The limitation on the minimum creepage distance is to prevent creepage between the two electrical conductors through contaminants that may appear on the surface of the insulating material.
Creepage distance In operation, the shortest insulation distance between two live conductors to be installed is greater than the minimum allowable creepage distance.
When determining the clearances and creepage distances, various conditions of use and environmental factors such as rated voltage, pollution conditions, insulation materials, surface shape, position direction, and withstand voltage duration should be taken into consideration.
