Mining cables, suitable for transmission in mines, can be used or fixed. ?
　　射频电缆按绝缘型式分类（1）实体绝缘电缆在这种电缆的内外导体之间全部填满实体高频电介质，大多数软同轴射频电缆都是采用这种绝缘型式。（2）空气绝缘电缆电缆的绝缘层中，除了支撑内外导体的一部分固体介质外，其余大部分体积均是空气。

450/750 v, PVC insulated control cable is suitable for the 450/750 v dc and ac 50 hz, rated voltage of the power plants, power plants, factories, mines, ports and petrochemical enterprises such as long-distance control loop, as between electrical instrumentation and automation instrumentation cables, phoresy all kinds of electric energy role, make the entire electrical system safe and reliable operation.

　　把单根绝缘线按不同节距扭绞成对，以大限度地减少串音，并采用规定的色谱组合，以便识别线对。缆芯：:缆芯结构以25对为基本位，超过25对的电缆按单位组合，每个单位用规定色谱的单位扎带包扎，以便识别不同单位。



　　任意两端及任一端子与接地之间在接通1000V交流时，1min应无击穿或飞弧现象。导线与接线端子之间的接触电阻
