Description

Technical Field

[0001] The utility model relates to the technical field of data transmission cables, in particular to a high-strength, ultra-low-loss, lightweight data transmission cable. Background Art

[0002] At present, ordinary data transmission cables on the market generally do not have good tensile resistance and low tensile strength. When pulled by external force, the external force directly acts on the cable core, causing the conductor or insulation of the cable to deform and break, rendering the cable unable to work. In addition, polyperfluoroethylene propylene is used as insulation, and polyperfluoroethylene propylene has a high density, resulting in a heavy product weight, and relatively poor flame retardancy and fire resistance, making it difficult to guarantee its safety. Utility Model Content

[0003] The purpose of the utility model is to provide a high-strength, ultra-low-loss, lightweight data transmission cable, which can achieve low transmission attenuation, low signal loss, fast data transmission, and enhanced conductor antioxidant capacity by adopting a silver-plated copper conductor core.
