How much is the rate of scrap copper out of the communication cables?
Usually by a few or several groups (each with at least two wire cable) similar rope twisted, mutually insulated wires between each group, and often around a central twisted, the entire outer covering layer of highly insulated bread. The cable has the characteristics of internal electricity and external insulation.
A wire made of one or more insulated conductors and insulated protective layers that transfer power or information from one place to another.
Cable output rate = net copper weight / cable gross weight *100(electric cable; power cable): usually consisting of several or several wires.
