The rated voltage is the voltage at which the high-voltage connector can work normally for a long time. The rated voltage is one of the core functions of the high-voltage connector. It and the rated current determine the power transmission capacity of the high-voltage connector, and also determine the insulation protection level of the product.
Note: Rated voltage is one of the main factors of electrical polarization of insulating materials.
Impulse voltage: usually based on the maximum rated voltage of the product’s working condition and the overvoltage category as the basis for its transient impulse voltage value.
The function of insulation protection is to prevent the short circuit of charged components with different potentials from causing damage to objects and people.
In product design, after comprehensively considering the working conditions of the product and the selection of product insulation materials, it is finally attributed to the value of creepage distance and clearance to quantify. Therefore, creepage distance and clearance are two aspects of product insulation protection design. Key factor.
