Why do electronic wiring harnesses need withstand voltage testing?

      Electronic wiring harness is a necessities we need, why do we need to carry out withstand voltage test on electronic wiring harness? Is there any benefit to doing this?

      The electrical wiring harness withstand voltage test is to ensure that the amount of current can easily flow from one point to another. This test will demonstrate the conformance of the cable and its ability to withstand high voltages for a given power consumption. Especially in cable assemblies or vehicle wiring harnesses, its testing can ensure excellent protection in the middle of various parts of the power circuit, and ensure the safety factor and quality of the whole power circuit.

      The necessity of an electrical wiring harness withstand voltage test depends on its ability to accurately measure the insulation level of a particular device or component. The test shows the professional technician whether the cable jacket can handle all transient overvoltages, i.e. causing a positive charge. Conditions that "promote" the movement of wires or other electrical conductors. In order to ensure that electrical equipment insulation meets safety and product quality standards, electrical equipment insulation must be exposed to high voltages for a long time.
