Insulation distance

In electrical and electronic circuits, this refers to the required distance between a component that needs electrical insulation and other components. There are two types of insulation distances: clearance, which is the direct line distance, and creepage distance, which follows the surface of the substrate on which the components are mounted. The insulation distance is influenced by the thickness and resistivity of the insulating material between the components. The greater the thickness or resistivity of the insulating material, the shorter the required insulation distance. Types of insulation include basic insulation, functional insulation, supplementary insulation, and reinforced insulation (double insulation), and each type has specific requirements for insulation distance according to electrical and electronic equipment standards.
