CABLE FOR SHIELDING ELECTROMAGNETIC WAVE AND PREPARATION METHOD FOR COPPER- IRON ALLOY OF CABLE

摘要

Provided is a cable for shielding an electromagnetic wave, characterized in that it comprises: cable cores, made of conductors (1); insulator layers (2), covering and surrounding the cable cores; a shielding material layer (4), covering and surrounding the outside of the insulator layers (2); and a protecting layer (5), covering and surrounding the outside of the shielding material layer (4), wherein the shielding material is made of a copper iron alloy, the copper iron alloy comprises a copper substrate and crystal particles which are dispersed in the copper substrate, with iron as the main ingredient and the content of iron being 5%-45% of the total weight of the copper iron alloy by mass. The cable can have an improved effect of shielding of the electromagnetic wave, has a more artistic appearance, and has a lighter weight, without conflict resulting from the improper use of a ferrite magnetic core. In addition, the copper iron alloy has excellent mechanical strength, and can enable a reduced diameter of the shielding wire body, so that the weight of the cable is lightened, making contribution to the operating production.
