| description | The utility model relates to a polytetrafluoroethylene rope winding type insulation soft copper tube shielding low-attenuation radio-frequency cable, which is widely used in mobile communication, microwave transmission, navigation systems and the like. The polytetrafluoroethylene rope winding type insulation soft copper tube shielding low-attenuation radio-frequency cable comprises a silver-plated copper wire inner lead, a polytetrafluoroethylene rope insulating layer, a spiral copper tube outer conductor and a fluorinated ethylene propylene sheath, wherein a plurality of circles of polytetrafluoroethylene rope are wound on the silver-plated copper wire inner lead to form an insulating layer, a layer of the spiral copper tube outer conductor and the fluorinated ethylene propylene sheath are sequentially arranged outside the insulating layer, and the plurality of circles of polytetrafluoroethylene rope are arranged at continuous intervals. The polytetrafluoroethylene rope winding type insulation soft copper tube shielding low-attenuation radio-frequency cable has the advantages of greatly reducing the dielectric constant of the whole insulating layer, reducing the attenuation of the cable by at least 20%, ensuring that the cable has high shielding performance since the outer conductor adopts the form of longitudinally-wrapping and welding the copper belt and rolling spiral rings, and improving the flexibility of the cable. |
