[0027] like Figure 2 and Figure 3 As shown, the copper stranded wire core 1 includes a copper stranded wire core 11, which is formed by twisting seven copper wires 111. The six copper wires 111 are evenly wrapped and twisted around the outer circumference of one copper wire 111, which greatly enhances the tensile strength of the copper stranded wire. A first coating 12 is provided on the outside of the copper stranded wire core 11.
