First, the basic evaluation indicators of conductive performance include the resistance value and conductive impedance of the wire. These parameters reflect the degree of obstruction when the current is transmitted in the wire. The lower the resistance value, the smoother the current transmission and the better the conductive performance.
Second, contact resistance is a direct indicator to measure the connection quality of cold pressed terminal wire. During the crimping process, if the contact area between the terminal and the wire is insufficient or the contact is not tight, the contact resistance will increase. Therefore, by measuring the contact resistance, the quality of the crimping process and the conductive performance of the terminal wire can be evaluated.
Third, voltage resistance is also an important aspect of evaluating the conductive performance of cold pressed terminal wire. It reflects the electrical insulation performance of the terminal wire when it is subjected to high voltage. If the voltage resistance is insufficient, it may cause electrical breakdown or flashover, affecting the safety and stability of the electrical connection.
Fourth, in practical applications, the conductive performance of cold pressed terminal wire can be evaluated by current load testing. Under a specific current load, observe the temperature change, voltage drop, and whether the connection is stable of the terminal wire. These parameters can intuitively reflect the conductive ability and thermal stability of the terminal wire.
Fifth, when evaluating the conductive performance of cold pressed terminal wire, its long-term stability must also be considered. During long-term use, the conductive properties of the terminal wire may change due to environmental factors, current load fluctuations and other factors. Therefore, regular inspection and maintenance are required to ensure that the conductive properties of the terminal wire are always in good condition.
Sixth, in order to accurately evaluate the conductive properties of the cold pressed terminal wire, professional testing equipment and instruments are required. For example, resistance testers, multimeters, etc. can be used to measure resistance values and contact resistance; withstand voltage testers can be used to evaluate withstand voltage strength.
Finally, the evaluation results should be compared with relevant standards and specifications. According to industry standards or enterprise specifications, the conductive properties of the cold pressed terminal wire are qualified. This helps to ensure that the quality of the terminal wire meets the actual application requirements.
