2) conducting wire is molded:Copper wire and aluminum steel are twisted together by cable conductor wire stranding machine, form conductive core;
3) insulation shaping:Granulated plastic heating is become viscous state by high-density polyethylene insulation material by the processing of extruder, Deformation is obtained under the action of machine barrel and head pressure, forming ring-type using the mold of head is coated on around conductor, shape Into insulating layer;
4) shielding shaping:Aluminium foil is first wrapped in the outside of insulating layer, the first metal screen layer is formed, is connected on the first metallic shield Stainless steel wire and copper wire are mutually woven in the outside of the first metal screen layer by braider by the outside of layer, form the second metal Shielded layer;
5) formable layer is buffered:Crumb rubber heating is become viscous state again by the processing of extruder, in machine barrel and head pressure Deformation is obtained under the action of power, forming ring-type using the mold of head is coated on around conductor, forms buffer layer;
6) formable layer is protected:The heating of protective layer granulated plastic is become viscous state in the processing by extruder, in machine barrel and machine Deformation is obtained under the action of head pressure, forming ring-type using the mold of head is coated on around conductor, forms protective layer.
