Classification by structure: The cladding wire is composed of multiple copper wires and steel wires mixed into a conductive wire core, and wrapped with insulating materials. It is tensile and abrasion resistant, making it easy to retract and reuse. It can generally be used for audio telephone, telegraph and single-carrier telephone communication within a range of 25 kilometers in field conditions.
