As a key connection component in electronic equipment, the electrical performance of Cold Pressed Terminal Wire is directly related to the operating efficiency and safety of the equipment. Therefore, it is particularly important to test the electrical performance of Cold Pressed Terminal Wire. The following is an introduction to the test methods for the three key electrical properties of Cold Pressed Terminal Wire: resistance, insulation resistance, and withstand voltage.Resistance test is the basis for evaluating the conductive performance of Cold Pressed Terminal Wire. By using a multimeter or an ohmmeter, the resistance value between the terminal wire and the conductor can be measured. During the test, ensure that the test instrument is well connected to the tested circuit to avoid test errors caused by poor contact. The smaller the resistance value, the better the conductive performance.The insulation resistance test is designed to verify the performance of the insulation layer of Cold Pressed Terminal Wire. Since the insulation resistance is generally high in value, it is usually tested with a megohmmeter. Before the test, the tested circuit needs to be disconnected from the power supply, and the tested object needs to be short-circuited to ground for full discharge. Then, connect the "ground" terminal of the megohmmeter to the grounding body, and the "line" terminal to the tested circuit. Shake the megohmmeter clockwise. When the speed stabilizes, the value indicated by the pointer is the insulation resistance value of the object under test. The larger the insulation resistance value, the better the insulation performance.The withstand voltage test evaluates the tolerance of the Cold Pressed Terminal Wire under high voltage conditions. During the test, a certain voltage is applied to the tested circuit using a withstand voltage tester and maintained for a period of time. Observe whether the tested circuit has breakdown, discharge and other phenomena. If there is no abnormal phenomenon, it means that the tested circuit has good tolerance under the specified voltage.In summary, resistance, insulation resistance and withstand voltage tests on Cold Pressed Terminal Wire can comprehensively evaluate its electrical performance and ensure its reliability and safety in electronic equipment. When conducting tests, they should be carried out in strict accordance with the test standards and requirements to avoid test errors caused by improper operation. At the same time, for Cold Pressed Terminal Wire with abnormal test results or non-compliant requirements, they should be replaced or repaired in time to ensure the normal operation of the equipment.
