Specifically, in the embodiment, the sheath is formed by longitudinally wrapping a copper strip with the thickness of 0.05mm into a tubular shape through a longitudinal wrapping process and extruding a layer of high-flame-retardant sheath on the copper strip for one-step forming, and the thickness of the sheath is 0.8mm, so that the cable has excellent temperature resistance, shielding performance and moisture resistance.
The first shielding layer 114 is a silver-plated copper braid. Specifically, in this embodiment, the silver-plated copper wire braid layer is a braided mesh formed by braiding a silver-plated copper wire with a diameter of 0.2mm by using a high-speed braiding machine, and the braiding density is 95%. The braided shielding layer enables the cable to be light and soft, and the shielding performance of the cable is enhanced. Such materials are commercially available.
