Method for detecting cold pressed copper tube terminals: Based on the cross-sectional use of the wire, we need to peel off the insulation layer of the wire to ensure that its length meets the corresponding requirements. All the metal wires in the wire are in the cold pressed copper tube terminals, and the requirement is that there are no scattered copper wires. According to the corresponding regulations, ensure that all parts that need to be crimped are correct. Strength can also be tested according to corresponding standards. If the crimping tools we use meet the standards, it is best to test them every three months.
