Cable and wire classification

- May 13, 2020-

There are thousands of kinds of wires and cables, which are used in all walks of life. There are two general USES, one is to transmit current and the other is to transmit signalsThe main technical indexes of current transmission cable are conductor resistance and voltage resistance. The main technical performance indicators of transmission signal cables are transmission performance -- characteristic impedance, attenuation and crosstalk. 


Of course, the transmission signal mainly depends on the current (electromagnetic wave) as the carrier, now with the development of science and technology can use light wave as the carrier to transmit.Generally speaking, cables can be divided into six categories: bare wire, electromagnetic wire (enameled wire), power cable, electric spare wire and cable, communication and telecommunication cable, optical cable.
