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.

但究其功能定位而言，谁又能说不是呢？不过以上这些都是一些专用的、具体硬件。个人计算机中的人机界面。个人计算机的出现，给我们展现出一种典型的、通用的、似乎无所不能的，而且越来越聪明的工具。它已经渗透到我们生活的每一个角落，这里暂且不去研究它的核心功能——计算和存储。仅看它所使用的一整套人机界面，也就是我们十分熟悉的“三件套”：显示屏、键盘和鼠标。多年的实践表明，是十分成功的。可以说已经成为了当前人机界面的基本模式。

　　参数说明::::钢丝铠装屏蔽控制电缆_KVVP32、KVVP2-32的使用特性：1、导体长期允许工作温度为70℃。2、敷设时环境温度≥0℃。3、小弯曲半径：4、无铠装层电缆，应不小于电缆外径的6倍。5、有铠装或铜带屏遮结构电缆，应不小于电缆外径的12倍。
　　屏蔽对与屏蔽对具有较好的绝缘性能，电缆在使用中若屏蔽对屏蔽对之间出现电位差时，不会影响信号的传输质量。用于以电子计算机为主的自动控制系统,尤其适用于计算机集散控制系统,传递生产装置过程变量的检测、控制、联锁、报警等模拟和数字信号。

　　常用全塑电缆规格代号的意义一般常用全塑电缆规格代号排在电缆型号的后面，常用数字表示。（2） 市内用市话全塑电缆的结构（H）凡是电缆的芯线绝缘层、缆心包带层和护套，均采用高分子聚合物塑料制成的，就称为全塑电缆。



　　一、适用范围本产品适用于交流额定电压300/500V或直流1000V及以下电子计算机网络及自动化控制系统的信号传输、抗干扰性能要求较高的检测装置和仪器仪表的连接。二、执行标准 SPTL/三、使用特性 1.电缆导体的长期允许工作温度应不超过70℃，在使用过程中电缆应防止高温直流辐射或接触；电缆敷设环境温度应不低于0℃。

　　同样的道理，如果有屏蔽线起到屏蔽作用的话，外部干扰源对于其的干扰影响也可以尽可能的缩小。3.选择使用普通的超五类屏蔽双绞线即网线就可以。由于原材料价格上涨，导致现在市场上的线材鱼龙混杂，有不良商人利用某种合金来顶替铜丝来做网线，在外面镀铜以蒙混客户。

一个浅显的道理是，对新电工来说电气运行、检修、电力安全等教育，单次再有声色的安全教育，古人讲究“因材施教”，电力新员工何尝不是？在安全教育的方式方法上，一切僵化、死板的模式都须改正，多一些创新的培训方式、丰富的培训内容未常不可。重要的应是始终站在新员工的角度，让危险点分析、风险辨识、风险防范、技术培训、岗位练兵等“规定动作”常态化、规范化，让培训具有指导性、针对性和实效性，久久为功、接续长期地开展才有更好的效果，才能更入脑入心，才会有效果。
