下面来解析一下每个词的含义：1.硬件区别于软件，从“弱电”字面意义和人们使用习惯，弱电主要偏重于硬件系统方面。
系统区别于单品和单品的简单联接，具有复杂性、集成性和整体性。
民用区别于涉及航空航天、电力能源、轨道交通、化工冶金等特殊领域或行业的智能管理和生产系统及人工智能等高技术研发领域。
智能泛指通过信息采集、传输、控制、管理等手段结合配套的机械和电子设备为人们的工作、学习、生产、生活和公共管理等方面提供安全、舒适、健康、便捷、高效、环保的智能体验。
充油电缆主要电气性能：1.充油电缆直流电阻:20℃,0.4≤1480.5 ≤95.00.6≤65.80.8≤36.62.充油电缆绝缘电气强度：导体之间1min1kv不击穿导体与屏蔽1min 3kv不击穿3.充油电缆绝缘电阻：每根芯线与其余线芯接地，HYAT电缆大于3000MΩ.k。
Sheathed control cable is introduced: polyvinyl chloride insulated fine steel wire armoured or steel tape armoured polyvinyl chloride sheathed control cable for mine, for laying indoors, in cable trench, pipelines, and underground shaft, in the male by certain pulling force function and the function of external mechanical forces.
HYAT23 armoured communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and vulnerable to erosion area and design of telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. ? 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter.

下面这些观念会更加实际：工作中很多地方用到PLC，那么我至少应该对它有基本的了解。
学习任何技能都不是一蹴而就的，至少要给自己2~3年时间去尝试。
有基础、学历高的人肯定入门快，我基础差那就多花时间、精力，多请教，实在不行能把现在维护设备的程序搞明白也可以。
如果我打算学习PLC，那么学习的目的是什么？是为了完成现在的工作、还是掌握了PLC老板会给涨工资，还是以后就打算从事这行，得先把学习目标确定下来。
误区纠结品牌你现在能用到（接触到）那个品牌的PLC，就学那个。

聚氯乙烯绝缘和护套阻燃控制电缆聚氯乙烯绝缘和护套阻燃控制电缆是聚氯乙烯绝缘和护套控制电缆的更新换代产品，该产品除具有聚氯乙烯绝缘和护套控制电缆的性能外，还具有良好的阻燃性能。
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。
