It can increase the flexibility and bendability of cables, and the twisted core is tightly compressed to improve the stability of the conductor structure, reduce the outer diameter of the conductor, and reduce insulation and protective layer materials, which is conducive to achieving longitudinal water resistance of the conductor. The product is mainly used in various fields such as transmission and distribution of medium and low voltage cables, fire-resistant cables, wiring, through wires, new energy power transmission, intelligent equipment power transmission, etc.
