Coaxial cables are often used for device-to-device connections, or in bus-type network topologies. The central axis of 3F coaxial cable is a silver-plated or nickel-plated copper wire, plus a layer of Teflon insulation material, outside this layer of Teflon insulation material is a shielding layer wrapped by a hollow cylindrical mesh copper conductor , the outermost layer of sheath is PVDF insulation layer. Compared with ordinary cables, coaxial cables have the advantages of strong anti-interference ability, good shielding performance, and stable and excellent transmission data. Alkali, fire-resistant and non-combustible (VW-1), high strength, bending resistance, small external electromagnetic interference and other excellent properties, widely used in aviation, aerospace, communications, military, automobiles and electrical or communication equipment in harsh weather.
