[0002] Communication cables are used to transmit telephone, telegraph, fax files, TV and radio programs, data and other electrical signals. They are made up of one or more mutually insulated wires twisted together. Compared with overhead open wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less impact from natural conditions and external interference. They are communication lines composed of a cable core twisted together with multiple mutually insulated wires or conductors and an outer sheath that protects the cable core from moisture and mechanical damage.
