Abstract

The invention provides a coaxial leaky cable for 5G signal transmission. The leaky cable comprises a leaky cable conductor, a polyolefin insulating layer and an outer conductor, wherein the leaky cable conductor is of a hollow structure and used for transmitting signals, the polyolefin insulating layer and the outer conductor sequentially coat the leaky cable conductor, and a plurality of slottedholes used for improving signal transmission are formed in the periphery of the outer conductor at preset intervals in the axial direction and / or the radial direction through laser slotting. The outside of the inner conductor and the inside of the outer conductor are coated with graphene coatings, so that the conductor loss of a product is reduced, and the cable can transmit higher frequency; thethree-layer co-extrusion physical foaming technology is directly adopted for the inner conductor and the outer conductor, and the insulation equivalent dielectric constant is reduced. And a laser slotting mode is adopted, so that denser and more accurate slotting can be realized. The cable provided by the invention has excellent electric conduction and optical properties and better heat conductionperformance and is higher in mechanical strength, and the cable is economical and practical.

Description

technical field [0001] The invention relates to the technical field of communication cables, in particular to a coaxial leaky cable used for 5G signal transmission. Background technique [0002] Leaky coaxial cable, also known as leaky coaxial cable, consists of three parts: inner conductor, insulating medium and outer conductor with periodic slots. While the electromagnetic wave is transmitted longitudinally in the leaky cable, the electromagnetic wave is radiated to the outside through the slot; the external electromagnetic field can also be induced into the inside of the leaky cable through the slot and transmitted to the receiving end. The leaky coaxial cable is suitable for various existing wireless communication systems, and its applications include subways, railway tunnels and road tunnels where wireless propagation is limited. [0003] The current radio frequency coaxial cable is mainly insulated by foamed polyethylene, and the outer conductor of the longitudinal co...
