Abstract: Braiding technology is an indispensable production technology in the wire and cable industry.The main functions of braiding are electromagnetic shielding,Armor protection,longitudinal tensile,boot fault current and to transmit electromagnetic waves as external conductors.In this paper,through the verification of the test performance of the mixed braiding technology of two kinds of cables with different types and specifications,three kinds of different mixed braiding structures are recommended,so as to achieve the stability of the cable shielding performance and reduce the cost.
