The technical performance difference between using two single lines together and the "double line structure design" is that when two single lines are used at the same time, they are prone to entanglement and breakage. When two single lines are auxiliary, they cannot achieve equal length and parallel use, and the distribution of tensile force points is uneven, which can lead to uneven order of fracture of the two single lines. The tensile strength can only reflect the strength of one line. The "double line structure design" has already glued two branch lines together. Due to structural changes, its technical performance has formed *, which can be used in equal lengths and parallel. The tensile force points are evenly distributed, forming a unified tensile strength technical index, breaking through the influence of low tensile strength of existing tracer line products.
