Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.

一个交换机能带动多少个网络监控摄像头？千兆交换机一般接200万网络摄像机几个？24个网络头，用一台24口百兆交换机行不行？今天我们就这些问题，来系统深入地了解一下。根据摄像机的码流和数量来选择摄像机码流选择交换机前，首先要弄清楚每路图像占用多少带宽。摄像机数量要弄清楚交换机的带宽容量。常用交换机有百兆交换机、千兆交换机。它们的实际带宽一般只有理论值的60~70%，所以它们端口的可利用带宽大致是60Mbps或600Mbps。

　　接地引出线要求采用我镀锡编织铜线，和电缆铜带连接时应用铬铁锡焊，不宜用喷灯封焊，以免烧损绝缘。 ③三相铜带屏蔽应分别与地线相连，注意屏蔽接地线和钢铠接地线应分别引出，相互绝缘，焊接地线的位置应尽量靠下。
