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.风景优美的圣朱尼佩罗，内向平凡的女孩约克夏（麦肯兹·戴维斯 Mackenzie Davis 饰）邂逅了光芒四射的凯丽（古古·玛芭塔劳 Gugu Mbatha-Raw 饰），两人之间产生了一段美好的感情。徐文长正色道，此外，你有一块在东海之内，绝无仅有的护身符。现在尹旭还对另外一件事情敢兴趣，沉声问道：徐建，你家船运是否在江东各地都有船行，或者据点什么的？据点？徐建一时有些没搞清楚尹旭的意思，略微的沉思之后才明白过来，立即点头道：是的，在江东和淮泗一带每个城池码头，徐家都安排有人手……尹旭顿时一笑，他要的就是这个东西，他一直想要要发展情报系统。二人先后落座，斟茶，以茶代酒。
