Description
Technical Field
The utility model relates to the technical field of network cables, in particular to a high-transmission double-shielding eight-type network cable.
Background
The non-shielding network cable has a simple structure, is convenient to manufacture, has low price, is widely applied to network data transmission, and is developed along with the times, new electromagnetic interference sources are continuously generated in the surrounding environment in production and life to influence the network data transmission, electromagnetic radiation can be generated in the transmission process of the network cable, the attention of consumers to the aspect is higher, so that the network cable needs to be improved, the external electromagnetic interference is prevented from entering the inside of the network cable, meanwhile, the signal inside the network cable is prevented from radiating outwards, the shielding network cable is also generated on the market at present, and most of the shielding network cables adopt round sheaths and are not easy to fix.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the present invention is to provide a high-transmission double-shielded eight-type network cable, which is used for overcoming the defects of the prior art.
In order to solve the technical problems, the utility model adopts the technical scheme that:
a high-transmission double-shielding eight-type network cable comprises four twisted pairs, wherein the outer sides of the twisted pairs are wrapped with inner shielding layers, the twisted pairs are arranged side by side, and the twisted pairs are separated by a straight framework; the outer sides of the four twisted pairs are wrapped with outer shielding layers, and the outer sides of the outer shielding layers are sleeved with square sheaths; the bottom of the square sheath is pasted with a glue layer, and the bottom of the glue layer is pasted with a sticker.
Furthermore, the inner shielding layer is an aluminum foil layer, and the outer shielding layer is formed by weaving tinned copper wires.
Furthermore, the twisted pair is formed by twisting two conductors, wherein each conductor comprises a transmission line and an insulating layer wrapped outside the transmission line; the transmission line is formed by mutually twisting two oxygen-free round copper wires.
Furthermore, the glue layers are uniformly distributed and arranged, and the intervals between the glue layers are 50 cm.
Furthermore, the square sheath is made of high-flame-retardant low-smoke halogen-free polyolefin material.
