　　 6KV及以上电缆接头： ①安装电缆终端头时，必须剥除半导体电屏蔽层，操作时不得损伤绝缘，应避免刀痕凹凸不平的情况，必要时用砂纸磨平；屏蔽端部应平整，并要把石墨层（碳粒）清除干净。②塑料绝缘电缆端头铜带屏蔽和钢铠必须良好接地，对短路也遵循这项原则，避免三相不平衡运行时钢铠端部产生感应电动势，甚至“打火”及燃烧护套等事故。

从横向纵向拓展性和发展潜力来看，总的来说嵌入式比单片机更具潜力，单片机比嵌入式容易入行。ARM芯片这么个标题我想说什么呢？意思是单片机跟嵌入式是有区别的。这篇文章就是来分析要如何选择，是学嵌入式还是单片机呢？我们朱老师物联网大讲堂推出的课程就有单片机跟嵌入式两个系列课程，有同学会觉得说单片机就是嵌入式，老师为什么要推出两个呢？这两个课程的内容是不一样的。单片机课程主要是讲51单片机跟STM32，51单片机主要是裸机，没有操作系统，有同学说51单片机也可以上操作系统，话虽如此，但一般不需要这样用。

，如果插座意外短路，即使是后者铰接到一起的，也有可能烧坏。一般解决方法就是：涮锡前接一个短头，然后把短头另一端接到接线柱上。这种是并联这种接线的大优点：每个插座坏了，都不会影响其他插座的使用。因为火线零线和地线都是从母线上引下来的。接线的时候一般是把母线的绝缘层去掉一点，然后采用T型接线。三种接法：导线有单股的也有多股的这种接法节省，但是接点怎么处理。如果在接线位置放一个线盒也可以。如果是吊顶的了，线盒都省了。

Flame retardant cables and fireproof cables: the difference between the average person is very easy to confuse the concept of flame retardant cables and fireproof cables, although there are many more flame retardant cable applies to the advantages of chemical enterprise, such as low, low smoke, non-halogen, but in general, fire-resistant cable can replace flame retardant cable, and flame retardant cables can't take place of fire-resistant cable.

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 buried depth of 1-35kv cable is not 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 is not 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. 6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be cleaned. (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 accidents such as burning sheath. 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 erosion of water and other corrosive materials, so as to prevent breakdown due to the aging of the insulation layer caused by water trees. 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 done by the installation personnel or full-time technical personnel familiar with the performance of wire and cable. If there are still unclear matters, please consult the relevant technical department or the technical department of our factory.
