Insulation Resistance And Withstand Voltage Analysis Of Heavy-duty Connectors

The insulation resistance of heavy duty industrial connector plugs is primarily affected by factors such as insulation material, temperature, humidity, and contamination. The insulation resistance values ​​provided in heavy duty male female connector plug samples are generally specified under standard atmospheric conditions. This means that the insulation resistance values ​​of heavy duty multi pin connectors plugs may decrease to varying degrees under certain environmental conditions. Also, pay attention to the insulation resistance test voltage for heavy connector plugs. Different voltages are applied based on the equation: insulation resistance (MΩ) = voltage applied to the insulator (V) / leakage current (μA). Different results are obtained by applying different voltages. In heavy duty cable connectors plug testing, the applied voltages are generally 10V, 100V, and 500V.

The withstand voltage of a heavy power connector plug is the critical voltage that can withstand a voltage greater than the rated voltage between the insulated parts of a contact pair, or between an insulated part and ground, for a specified time without breakdown. The withstand voltage of a heavy duty wire connectors plug is primarily affected by the spacing and creepage distance between the contact pairs, their geometry, the insulator material, the ambient temperature, humidity, and atmospheric pressure.
