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.

Steel tape armoured mainly as the radial mechanical protection layer of the cable, and it also have additional total shielding effect, especially steel tape armoured and copper wire, copper tape screened, is adopted two different shielding materials, play a complementary role in electromagnetic wave shielding, shielding effect will be better.

三极管按材料分有两种：硅管和锗管。而每一种又有NPN和PNP两种结构形式，但使用多的是硅NPN和锗PNP两种三极管，（其中，N表示在高纯度硅中加入磷，取代一些硅原子，在电压刺激下产生自由电子导电，而p是加入硼取代硅，产生大量空穴利于导电）；两者除了电源极性不同外，其工作原理都是相同的，下面仅介绍NPN硅管的电流放大原理。对于NPN管，它是由2块N型半导体中间夹着一块P型半导体所组成，发射区与基区之间形成的PN结称为发射结,而集电区与基区形成的PN结称为集电结,三条引线分别称为发射极e（Emitter）、基极b(Base)和集电极c(Collector)。
