Signal cable for mining is a signal transmission tool. General signal cable transmission signal is small, in order to avoid the interference signal, signal cable with a layer of shielding layer, outside package of conductor shielding layer, generally for conductive cloth, woven or copper (aluminum), the bronze shield to ground, external interference signal can be the layer into the earth, and avoid interference signals into the inner conductor interference at the same time reduce the wastage of the transmitted signal.

一定要熟悉系统和规程，实际电气工作大多是很死板的停送电工作而已，如果熟悉系统，干活利索，这也是挺不错的。
当然安全是要保证的，学电气，不该动的千万不要动，否则会吃不少亏，相信大家看了我的帖子，也发现我这人缺点不少，比如干活太冲动，马马虎虎，有时爱逞能等等，无论怎样，必须要有自己的底线，就拿停送电来说，不管你再马虎，哪怕干错了，都没什么说的，切记保命的两点，一是查开关在断，二是查地刀在拉开。
切记，安全第一。
BV line, BVR line, RVSP double stranded shielded cable, RVS double stranded cable, RVB parallel line, RV line RVSP Shielded twisted-pair cable RVSP (shielded twisted-pair cable, shielded cable, shielding twisted-pair electric (HYVP, RVVP) RVVP twisted-pair shielded cable < < shielded wire > > is shielded twisted-pair cable RVSP series on the basis of RVS coupled with a layer of copper wire shielding net, so the transmission loss, shielding the outside world better than RVS series, but because of the copper wire shielding network, its cost is also much higher than RVS series. Are often used to those who has a high re on the transmission.

硬压板：硬压板是指保护柜内连接片之类的硬件设备，就是看得见、摸的着，实实在在的物体。
硬压板：是保护装置联系外部二次回路接线的桥梁和纽带。
硬压板分类：功能压板、出口压板。
功能压板作用：实现保护装置的功能（如：差动保护、距离保护、零序保护、复压过流保护等的投、退。
）功能压板一般为直流24V的弱电压板。
保护装置里面的24V电源模块不接地，功能压板的上下端口对地无电压（如：一节干电池，你分别测量干电池两极对地是无电压的，只有测量干电池两极之间才会有电压；当然，或许你会困惑为什么直流系统能测量到两极的对地电压，原因在于我们的直流系统绝缘监测装置是接地的，提供了地参考点，能测量到两极的对地电压。
