What is the climbing distance of transformer bushing?

The creepage distance of transformer bushing is the abbreviation of creepage distance, which refers to the shortest distance from one conductor to another along the insulator surface between two conductors, rather than the spatial distance between two conductors. The creepage distance is divided into four grades, which are related to the degree of pollution, and 25mm/kV belongs to the secondary pollution prevention. Since the technical requirements are specified, they must be met.
