What is the difference between an ordinary signal cable and a communication cable?
Control and communication cable is current and voltage is relatively low, but because the signal is analog switch and even high frequency signals (such as TV video signal), vulnerable to electromagnetic interference and the signal distortion or error signal, which has a great influence on the precision, accuracy and images, sounds, or even serious accidents, so this kind of signal cable shielding requirements are high, the main is to ensure that the signal is not affected by outside interference or reduced
Power cable is the power supply for the operation of equipment. It is characterized by higher voltage and higher current. Therefore, high voltage resistance of this kind of cable is required;
