In reality, many friends home decoration will generally carry out water and electricity transformation, so, when the water and electricity transformation, many families are choosing to change the line, even if not change the line for breakpoint transformation, but also need to buy copper wire, therefore, personally think it is necessary to understand some knowledge and skills to distinguish the good or bad copper wire.

After getting the copper wire, the first thing to do is to look at the appearance of the copper wire, including the appearance of the copper wire packaging and the appearance of the copper wire insulation layer. The first thing to look at the appearance is to look at the copper wire packaging. The packaging of the copper wire should have all the parameters, certificates and implementation standards of the copper wire, and then open the package and look at the insulation mark of the copper wire. The insulation layer has the manufacturer's label, line diameter model and other information. Here is a tip, once found that the small mark is vague, or even no, then, this is definitely unqualified copper wire products.

The second is to see the diameter of the copper wire, a copper wire quality is actually a bright spot, one is the insulation layer, two is the copper wire core, insulation layer to ensure the insulation resistance value of the copper wire, and the copper wire core is to ensure the carrying capacity of the copper wire, the copper wire can be pulled out a section, until exposed inside the copper, if the copper wire is found to be purple, that is, the so-called copper, Quality is the best. In addition, we can bend the copper wire by hand. If it feels soft, then it is a good copper wire. On the contrary, we find that the wire is yellow, then it is brass, and there are other impurities in it, and the quality is not good

The above is a summary of the methods to identify the quality of copper wire, I hope to be able to select copper wire to you, if you have more understanding of copper wire welcome to communicate with us.
