Creepage distance "is a key safety parameter in electrical equipment design, which refers to the shortest path distance between two conductive components measured along the surface of the insulation material. When the surface of the equipment forms a leakage path due to dirt and moisture, a short creepage distance may cause arcing or leakage on the insulation surface, leading to short circuits or even fires. Unlike the "electrical gap" that emphasizes air insulation, the creepage distance focuses more on the voltage resistance of solid insulation surfaces. In humid and dusty environments, there is a higher requirement for creepage distance. Correctly understanding and ensuring sufficient creepage distance is the foundation for ensuring the long-term safe operation of household appliances and power distribution devices in any environment.
