RVV7X0.2电缆格古县高品质HYA30对0.5市话电缆整洁
现在将一些错误的观念作出一些澄清。1.485信号线可以和强电电源线一同走线。在实际施工当中，由于走线都是通过管线走的，施工方有的时候为了图方便，直接将485信号线和电源线绑在一起，由于强电具有强烈的电磁信号对弱电进行干扰，从而导致485信号不稳定，导致通信不稳定。
本产品具有较强的抗电磁干扰、抗雷击及均匀电场，改善供电品质的特性，特别适用具有精密电子装置的场所，如计算机中心、航空航天监控中心、智能大厦等金属屏蔽电力电缆只是在设计结构上与交联聚乙烯绝缘电力电缆和聚氯乙烯绝缘电力电缆有所不同，在型号上以“－P”后缀加以区分，如：VV-P、YJV-P、YJLV22-。
3、外导体编织一般60%-80%为宜，偏大对降低衰减效果不是很明显。4、绝缘生产用的模具设计和加工也是关键，应该保证产品达到较理想的均匀结构，使等效介点常数达到设计要求。5、物理发泡PE其衰减在低频是合格，而高频（如超过800MHz）时超差，大都与和等效介点常数偏大有关系，或者与外导体编织密度过小，内导体外直径偏小有关系。

一般是背板带宽和包转发率都满足的交换机才是合适的交换机。背板相对大、吞吐量相对小的交换机，除了保留了升级扩展的能力外，就是软件效率/专用芯片电路设计有问题；背板相对小、吞吐量相对大的交换机，整体性能比较高。摄像机码流影响清晰度，通常是视频传输的码流设定(包含了编码发送及接收设备的编解码能力等)，这是前端摄象机的性能，与网络无关。通常用户认为清晰度不高，认为是网络原因造成的想法实际是个误区。根据上面的案例，计算：码流：4Mbps接入：24*4=96Mbps1000Mbps4435.2Mbps汇聚：170*4=680Mbps1000Mbps4435.2Mbps接入交换机主要考虑到接入到汇聚之间的链路带宽，即交换机的上联链路容量需要大于同时容纳的摄象机数*码率。

绝缘线对：把单根绝缘线按照不同的节距扭绞成对，并采用规定的色谱组合以便识别线对，聚氯乙烯护套。用途：主要用于传输音频、150kHZ及以下的模拟信号,也可用于传输2048kbit/s以上的数字信号。适用于远程光网络单元到用户之间的传输系统，以及大楼布线系统中楼宇间传输的子系统。
Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the direct buried depth of 1-35kv cable is less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. ? 6KV and above cable connector:? When installing the terminal head of the cable, the semiconductor electrical shielding layer must be stripped off. During operation, the insulation shall not be damaged. The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. ? The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible. Basic re for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent water and other corrosive materials from corroding, in order to prevent the water tree caused by the aging of the insulation layer and breakdown. 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.

CPU的工作原理让我们通过一个具体运算3+4，来说明CPU的操作过程吧。假设保存在内存中的程序和数据如下。步骤1：当程序被执行时，CPU就读取当前PC指向的地址0000中的指令（该操作称为指令读取）。经过解码电路解读后，这条指令的意思是“读取0100地址中的内容，然后，保存到寄存器1”。于是CPU就执行指令，从0100地址中读取数据，存入寄存器1。寄存器1：03（由0变为3）由于执行了1条指令，PC的值变为0001步骤2：由于PC的值为0001，因此CPU就读取0001地址中的指令，经解码电路解码后，CPU执行该指令。
