Creepage distance is the shortest path along an insulating surface between two conductive elements of unequal potential. The insulating material around the long-term working conductor will be polarized, which will cause the insulating material to appear charged, so the design of the creepage distance is particularly important.
The main influencing factors of creepage distance are rated voltage, pollution degree, material category.
The electrical gap is the shortest spatial path between two unequal potential conducting elements. The electrical gap has nothing to do with the electrical polarization of the insulating material, and it is mainly to avoid the electrical breakdown caused by the impulse voltage.
The main influencing factors of electrical clearance are impulse voltage, electric field type, pollution level, material type, altitude and air pressure, etc.
The rated current carrying value is the current value transmitted by the high-voltage connector when it works normally for a long time. Rated current carrying is one of the core functions of high-voltage connectors. It and the rated voltage determine the power transmission capability of high-voltage connectors, and also determine the risk level of product thermal failure.
