Flame-retardant cable classification: according to the different flame-retardant materials of cables, flame-retardant cables are divided into halogen flame-retardant cables and halogen-free low-smoke flame-retardant cables. Which contain halogen flame retardant cable insulation, sheath, outer sheath and auxiliary material (package belt and filling) in whole or in part by polyethylene (PVC) containing halogen flame retardant material, thus has good flame retardant properties. However, when the cable burns, a large amount of smoke and haloic acid gas will be released. Haloic acid gas is corrosive to the surrounding electrical e When the cable burns, it will cause harm to the surrounding electrical e and rescue personnel, which is not conducive to the fire fighting and rescue work, thus causing serious "secondary hazards". All or part of the insulation layer, protective sleeve, outer protective layer and auxiliary materials (packing belt and filling) of the halogen-free low-smoke flame-retardant cable are adopted



　　U0--任一绝缘导体和"地"(电缆的金属护层或周围介质)之间的电压有效值。U--多芯电缆或单芯电缆系统任何两相导体之间的电压有效值，当用于交流系统时，电缆的额定电压应至少等于所使用电缆系统的标称电压。该条件均适用于U0和U值。

It is composed of different material conductors in metal sleeves with insulating materials, which are processed into a flexible solid assembly.

即在电路中有漏电时，漏电开关会自动跳闸，而空开不行。功能多了，所以就好？也不尽然。漏电开关在提供漏电保护的时候，会造成两个后果：1.单一设备或线路漏电，会造成整个回路断电。这件事情放在家庭中不太明显，但如果是医院、商场、工厂等地，则有可能造成经济损失甚至危及人身安全。漏电开关对线路的检查存在误差，感应电、二极管、晶体管在工作时，都会被漏电开关判断为线路漏电，从而引起跳闸——这叫“误动作”。为了防止漏电开关误动作，将漏电开关的动作电流提高到了30mA（特殊场合使用的漏电开关动作电流值会更低）——人体安全电流的极值。

可控硅包括单向可控硅和双向可控硅两种，都有三个脚。单向可控硅的三个引脚分别是G（控制极）、K（阴极）、阳极（A）。双向可控硅的三个引脚分别是G（控制极）、T1（输入端）、T2（输出端）。双向可控硅其实就是由两只单项可控硅反向并联构成的。单向可控硅图分辨单、双向可控硅的方法，用万用表的RX1档分别对可控硅三个引脚进行两两正反测量，这样测完一个可控硅需要测6次，6次中测量中只有一次测量值为几十至几百欧，就可判定这个可控硅是单向可控硅。
