The outer surface is plated with oxygen-free copper, and the raw materials of the core wire are brass, bronze and miscellaneous copper. Because the raw materials of copper inside and outside are different, it is called copper clad copper. The quotation is moderate, and the quotation for miscellaneous copper is usually only half or lower than that for oxygen-free copper. The produced wire is attributed to non-standard wire, and its anti-twisting and anti-oxidation functions are better than those of copper-clad aluminum. Suitable for induction and wiring engineering with low accounting, it can lay hidden lines in the wall. However, due to the influence of raw materials, the resistance is relatively large, with a 100-meter resistance of 25-35 ohms or even more, and the signal attenuation is very large. It is not so-called all-copper. We pay attention to the distinction.臣随陛下多年，非要事不扰陛下，文华三劾，实是一次比一次重要。　　民间有五鬼作乱，馗施法收伏五鬼，并封为鬼王。这用得着猜吗？徐风撇嘴，不屑地说，我早就跟你说过了，归根结底不是流着同样的血，你看重的东西跟他看重的不一样。北魏文孝帝大和年间，北国突厥可汗吐利大肆兴兵，谋图中原。The Interface Segmentation Principle (ISP) means that it is better to use multiple specialized interfaces than to use a single total interface. That is to say, don't let a single interface take on too many responsibilities, but should separate each responsibility into multiple specialized interfaces for interface separation. Too bloated an interface is a kind of pollution to the interface.E. PrintStackTrace ();
