Abstract: |
|||
| This invention relates to a preparation method for special steel woven filaments for communication cable shield layers including rough drawing, plating, mid-drawing, fine-drawing and annealing of copper-wrapped steel filaments with the mechanical performance approaching to copper wires, the extension rate of which reaches to 20% and the tensile strength reaches to that of copper wires, so it will not be broken when used in weaving cable shield layers and the product will not be hard and keep fine flexibility. | |||
