Why do I need to perform voltage withstand testing on my electronic wire harness?

Electronic wire harnesses are a necessity that we need. Why do we need to perform voltage testing on electronic harnesses? Is there any benefit in doing so? Voltage withstand testing of electronic harnesses is done to ensure that the current flows easily from one point to another. The test will demonstrate the consistency of the cable and its ability to withstand high voltage for a given power consumption. Particularly in cable assemblies or vehicle harnesses, its testing ensures good protection between the various parts of the power circuit, ensuring a margin of safety and quality of the entire power circuit.
Vehicle wiring harnesses are the main network of automotive circuits. Without wiring harness, there is no automotive circuit. At present, whether it is a luxury car or an ordinary car, the form of wiring harness is basically the same, consisting of wires, connectors and winding tapes. New energy vehicle wiring harness function introduction: the wiring harness of new energy vehicles can be divided into two kinds: the power line that carries the power to drive the actuator and the signal line that transmits the sensor input instructions. In modern automobiles, there are many automotive wiring harnesses, and the electronic control system is closely related to the wiring harness. Once someone played a figurative analogy: if the function of the microcomputer, sensors and actuators compared to the human body, it can be said that the microcomputer is equivalent to the human brain, the sensor is equivalent to the sensory organs, the actuator is equivalent to the organ of motion, then the wiring harness is the nerves and blood vessels.
The form of wire harness is basically the same, are composed of wires, connectors and winding tape. Not only to ensure the transmission of electrical signals, but also to ensure the reliability of the connecting circuit, to provide the specified current value for the electronic and electrical components, to prevent electromagnetic interference to the surrounding circuit, and to eliminate electrical short circuits. The need for voltage withstand testing of electronic harnesses depends on their ability to accurately measure the level of insulation of a particular device or component. The test demonstrates to the technical professional whether the cable sheath is capable of resolving all transient overvoltages, i.e., inducing a positive charge. Conditions that "promote" the movement of wires or other electrical conductors. To ensure that the insulation of electrical equipment meets safety and product quality standards, the insulation of electrical equipment must be exposed to high voltages for extended periods of time.
