What are the methods for selecting the advantages and disadvantages of copper stranded wires?

Firstly, the selection of copper stranded wires needs to be observed from the appearance. Generally, good copper stranded wires have a relatively bright appearance, with obvious damage and scratches, and there will be no obvious discoloration caused by oxidation reactions. The outer color is relatively uniform, with black spots and cracks, and the distance is uniform and regular. Meeting the above standards is a good choice for copper stranded wire.
Secondly, the selection of copper stranded wire specifications and models requires observing the scale and specifications of the wire. Generally, the drawing of copper stranded wire should be within the specified range and should not exceed the process standards, otherwise it will be considered as an invalid stranded wire. The single wires that make up the stranded wire must meet the characteristics of uniformity and tidiness, and comply with the process rules.
Once again, when purchasing copper stranded wires, it is necessary to observe the distribution and composition of the stranded wires to see if there are any short wires, missing wires, loose wires, or overlapping wires. Generally, these can be observed with the naked eye, and we need to carefully observe and inspect the quality of the copper stranded wires. We cannot choose unqualified products for producing wires and cables, which can cause serious safety accidents.
Finally, when selecting copper stranded wire for welding process, it is important to pay attention to whether the welding process is reliable, whether the welding interface is neat, and whether there are uneven lines in service. The welding interface should be maintained neatly, leveled, rounded, and not tied to hands. The diameter of the welding head should generally not exceed 0.2 millimeters; The welding of two adjacent copper stranded wires should maintain a certain distance
