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.

　　一、产品简介电力电缆用输配电系统，本公司生产的交流额定电压0.6/1KV聚氯乙烯绝缘电力电缆和35KV及以下交联聚乙烯电力电缆，其性能不仅符合标准GB1276和IEC60502及IEC60840，并且已形成系列，即阻燃型的、耐火型的、耐寒型的和防水型的电力电缆。



　　也可提供双层护套的通信电缆。 具有防火，防潮等特点矿用通信电缆引发火灾的原因，主要是因为过负荷、短路、接触电阻过大及外部热源作用。在短路、局部过热等故障状态及外热作用下，绝缘材料绝缘电阻下降、失去绝缘能力，甚至燃烧，进而引发火灾。

上次投稿“欧姆龙和西门子一键启停PLC编程方法图解看完秒懂。”链接：m431651.html根据这个网有提出的问题，我专门编写一个这样程序，内容：5台电机顺序启动Y0.Y1.Y2.Y3.Y4.Y5，间隔5秒，然后停止时间间隔5秒，逆停：Y5.Y4.Y3.Y2.Y1.。程序编写完成，我截图给分享给大家。为了验证程序实用性，我专门在线仿真一下，我也截图分享给大家。我用的是台达编程软件，特地加上注释，分享给的大家，方便大家熟悉和后期在自己练习。

　　理论上RS485的传输距离能达到1200米，但实际应用中传输距离要小于1200米，具体长度受周围的环境影响。一般推荐如下：普通双绞屏蔽型电缆STP-120Ω（forRS485&CAN）onepair20AWG，电缆外径7.7mm左右。

但是在8051F310中，CIP-51微控制器内核采用流水线结构，与标准的8051结构相比指令执行速度有很大的提高。在一个标准的8051中，除MUL和DIV以外所有指令都需要12或24个系统时钟周期，大系统时钟频率为12-24MHz。而对于CIP-51内核，70%的指令的执行时间为1或2个系统时钟周期，只有4条指令的执行时间大于4个系统时钟周期。所以在计算定时器的值时要注意这里的变化。指令周期：指令周期是执行一条指令所需要的时间，一般由若干个机器周期组成。
