PLC好学吗？当初的手持编程器不能显示梯形图，只能够显示语句表，要想看懂就必须把语句表转换成梯形图来看，在学习了半年多时间以后，在当时我就是一手拿着板砖，一手拿着笔，摁一下，显示一行，在纸上画出梯形图，在来看。这个过程我的学习资料就有一本，就是他们复印出来的那本编程手册，不懂了看手册，懂了，在翻译成梯形图，就在我不知疲倦的翻译出一段程序后，大约是四十多张A4纸，耗时一个月左右，包括查资料学习。我们那里弄来了一台电脑，包括软件，在那上面一目十行的梯形图，让我感叹真他娘的浪费我的时间，可是转念一想，我还庆幸自己最初没有接触电脑编程软件，不然那些指令的学习透彻度肯定会降低。
用途：耐火电缆广泛应用于高层建筑、地下铁道、地下街、大型电站及重要的工矿企业等与防火安全和消防救生有关的地方，例如，消防设备及紧急向导灯等应急设施的供电线路和控制线路。 2.电缆敷设安装允许弯曲半径非铠装电缆应不小于电缆外径的10倍；铠装电缆应不小于电缆外径的15倍。
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。
The mine communication cable has the characteristics of fire prevention, damp proof and so on. The reason of fire is mainly caused by overloading, short circuit, excessive resistance and external heat source. Under the fault conditions such as short circuit, local overheating and external heat, the insulation resistance of insulating materials decreases, the insulation capacity is lost, and even the fire is caused.
Cable length: mechanically protected cable is manufactured according to the standard length of the corresponding basic cable.
也可提供双层护套的通信电缆。在缆芯中和屏蔽层的内外表面用石油膏填充或浇注处理，以防止煤矿中水分侵入。在煤矿常见的30~C一60~C的环境条件下，煤矿用通信电缆的机械和电气性能保持不变。用于平巷、斜巷及机电硐室做通信线以及用于平巷，竖井或斜井作主信号传输。

对电气伤害的防护检验人员在进行电梯的检验时，一定要做好全面的检查工作，要对使用到的一切电动工具进行排查，对有问题的设置必须要进行及时的处理，防止出现由于工具原因而产生的事故。如果目标对象是使用多年的电梯，这是就要重点关注其电缆是不是存在破损情况，尽量避免由漏电而引发的电击问题，同时使用相应的绝缘措施。如果电梯工作环境比较潮湿，那么工作人员就需要重点关注可能漏电的位置，防止由于潮湿环境而产生的电击伤害。
