When a user has the requirements of two functions of electric transmission and signal transmission, multiple cables are often selected, and when the cables are wired in an electric cabinet or a cabin with limited space, the multiple different cables occupy large space, are cumbersome to wire and have low reliability.
The existing common cable has poor anti-interference performance. The common cable in the market has poorer shielding performance, obviously reduces transmission performance when being interfered by external signals, and influences use; the common cable generally does not have low noise performance, and under the action of external factors such as bending, vibration, impact, temperature change and the like, the noise value generated by the cable is higher, so that signal transmission is influenced.
The existing common cable has poor mechanical and physical properties and environmental adaptability. The common cable generally has no good tensile drag, and when the common cable is pulled by external force, the external force directly acts on the cable core to cause the breakage of conductors or insulation of the cable, so that the cable cannot work. Ordinary cables generally do not have good environmental flexibility: when the cable is exposed to a high-temperature environment or a burning condition, the cable insulation and the sheath can be melted or even burnt; when the cable is exposed to a low temperature environment, the insulation and the sheath of the cable can crack, so that the cable fails and cannot be used.
Disclosure of Invention

The beneficial effects of the utility model are as follows: the high-temperature-resistant low-noise radio frequency cable conductor adopts a plurality of silver-plated copper conductive wire cores I, and has excellent transmission performance and high temperature resistance level; the conductor is coated with the noise reduction layer I, the insulating layer adopts a polytetrafluoroethylene pushing structure, the structure has excellent temperature resistance level and insulating property, and the noise reduction layer II is coated outside the polytetrafluoroethylene insulating layer, so that the radio frequency cable has good low noise performance; the shielding adopts a double-layer shielding combination mode, the inner-layer shielding adopts a wrapping silver-plated copper strip structure, the outer-layer shielding adopts a braided silver-plated copper-clad aluminum alloy wire structure, the combination type shielding has the characteristics of high shielding efficiency, excellent anti-interference performance and the like, the wrapping silver-plated copper strip has the characteristics of small volume and light weight, and the silver-plated copper-clad aluminum alloy has the characteristics of light weight, high shielding efficiency and the like when used as the shielding.
The reinforced core adopts the structure that the fusible polytetrafluoroethylene is extruded outside the aramid reinforced core, and the structure ensures that the cable has stronger tensile drag resistance, and meanwhile, the design has the characteristics of small volume, light weight, high temperature resistance and the like.
According to the utility model, a polytetrafluoroethylene film wrapping layer, a silver-plated copper strip inner shielding layer, a silver-plated copper wire woven outer shielding layer, a mica tape heat insulation flame-retardant layer and a cold-resistant flame-retardant elastomer sheath are sequentially arranged outside a total cable core. The polytetrafluoroethylene film is wrapped after the cable is assembled, so that the cable structure is more stable; the inner shielding layer of the cable is wrapped with silver-plated copper strips, and the outer shielding layer of the cable is woven with silver-plated copper wires. The wrapped silver-plated copper strip shield has the characteristics of small volume, light weight, high shielding efficiency and the like; the braided silver-plated copper wire shielding has the characteristics of high shielding efficiency, strong oxidation resistance, excellent weldability and the like.
The mica tape heat-insulating flame-retardant layer has good heat-insulating flame-retardant performance, and the structure can play a good protective role when the cable is burnt by flame, so that cable core insulation is prevented from being rapidly melted when the cable core insulation contacts flame to cause cable failure. The cable sheath adopts cold-resistant flame-retardant elastomer, and the material has good heat insulation flame retardance, and simultaneously has a certain cold resistance as the cable sheath, and is not easy to crack when being exposed in a low-temperature environment.
The cable has the advantages of small volume, stable structure, excellent transmission performance and strong anti-interference performance, and has excellent mechanical and physical properties and environmental adaptability.
