耐火电缆常见型号型号名称备注NA-YJV/NB-YJV交联聚乙烯绝缘聚氯乙烯护套A(B)类耐火电力电缆可敷设在对耐火有要求的室内、隧道及管道中。NA-YJV22/NB-YJV22交联聚乙烯绝缘钢带铠装聚氯乙烯护套A(B)类耐火电力电缆适宜对耐火有要求时埋地敷设，不适宜管道内敷设。
说的通俗些铠装电缆也就是地埋的电线电缆，动力线传输电能电缆加上铠装层的目的除了增强抗拉强度、抗压强度等机械保护延长使用寿命外，铠装的有一定的抗外力性能，还可以放一些老鼠撕咬，不至于透过铠装造成电力传输问题，铠装的弯曲半径要大，铠装层可以接地保护电缆计算机铠装电缆、计算机屏蔽铠装电缆：双屏双绞铠装电缆。
PLC的CPU单元对用户程序的周期性循环扫描，与PLC通讯处理器对各远程I/O单元的周期性扫描是异步进行的。尽管PLC的CPU单元没有直接对远程I/O单元进行操纵，但是由于远程I/O缓冲区获得周期性刷新，PLC的CPU单元对远程I/O缓冲区的读写操纵，就相当于直接访问了远程I/O单元。这种通讯方式简单、方便，但要占用PLC的I/O区，因此只适用于少量数据的通讯。全局I/O通讯方式全局I/O通讯方式是一种串行共享存储区的通讯方式，它主要用于带有链接区的PLC之间的通讯。
视频信号传输一般采用直接调制技术、以基带频率（约8MHz带宽）的形式，常用的传输介质是同轴电缆。同轴电缆是专门设计用来传输视频信号的，其频率损失、图像失真、图像衰减的幅度都比较小，能很好的完成传送视频信号的任务。
我们的拖链电缆种类繁多，芯数从单芯到60芯不等，单芯面积更是涵盖类了0.2-180的所有型号。导体结构：符合DINVDE02956类标准。芯线绞合：芯线小节距绞合成缆。绝缘：特殊丁腈复合料材料绝缘。2、铝箔、裸金属丝编织双层屏蔽，PVC外护套，阻燃,外观紫色。
为了提高电缆的质量，我们选择高电性能绝缘材料生产，例如1.8/3kv变频电机专用电缆，采用10kV交联绝缘材料，6/10kv变频电机专用电缆采用35kv交联绝缘材料，导体屏蔽、绝缘屏蔽和绝缘材料均采用了进口材料。
矿用电力电缆用途：本产品为煤矿用额定电压1KV及以下固定敷设用电缆，适用于煤矿井下的电力传输。矿用电力电缆用途：本产品为煤矿用额定电压1KV及以下固定敷设用电缆，适用于煤矿井下的电力传输。矿用电力电缆使用条件：线芯长期允许工作温度为65℃，电缆敷设温度不低于0℃，电缆允许小弯曲半径为15（D+d）±5%。

从技术原理上分析，漏电保护器也存在可能产生拒动的技术误区。1，当中性线产生重复接地时，会使漏电保护器产生分流拒动，而中性线重复接地点是很难找到的。2，当电源缺相，所缺相又正好是漏电保护器的工作电源时，会产生拒动。后还需特别指出两点：1.当发生人体单相触电事故时（这种事故在触电事故中几率高），即在漏电保护器负载侧接触一根相线（火线）时它能起到很好的保护作用。如果人体对地绝缘，此时触及一根相线一根零线时，漏电保护器就不能起到保护作用。
