Background

Communication cables are a general term for various wires for transmitting electrical or optical signals, and are classified into the following categories according to their structures:

the covered wire is formed by twisting a plurality of copper wires and steel wires into a conductive wire core and wrapping the conductive wire core with an insulating material, is tensile and wear-resistant, and is convenient to store, release and use repeatedly. It is usually available for audio telephone, telegraph and one-way carrier telephone communication within a distance of 25 km under field conditions.

Secondly, the overhead open wire is a bare metal wire for communication which is laid on a pole and comprises a galvanized steel wire, a hard copper wire, a copper-clad steel wire, an aluminum-silicon-magnesium alloy wire, a steel-cored aluminum stranded wire and the like. The transmission attenuation of the galvanized steel wire is large, and the galvanized steel wire is only used for three-way carrier telephones with audio frequencies or short distance. The remaining four conductors are used for carrier telephones having 12 or more conductors. The communication capacity of the overhead open-wire communication line is larger than that of a covered wire in field operations, the communication distance is far, but the target is obvious and easy to damage, and the communication quality is seriously reduced and even communication interruption is caused when the overhead open-wire communication line is attacked by ice, thunder, flood and storm.

Communication cables are generally composed of a cable core, a sheath and a sheath. According to the different cable core structures, the cable can be divided into a symmetrical cable and a coaxial cable. The insulated wires in the cable core adopt a structure form of two-wire pair-twisting group or four-wire star-twisting group, and the insulated wires in the cable core adopt a structure form of cylindrical inner and outer conductors which are mutually insulated and coaxially sleeved.
