Embodiment Construction

[0020] Such as figure 1 As shown, this embodiment is a Super Category 6 digital communication cable with a cross-section as figure 1 Shown: a double-layer Super Category 6 digital communication cable, including a cable core and an outer sheath, the cable core includes four pairs of twisted pairs evenly distributed in the outer sheath 3, the The cross section of the outer sheath is circular, and the four pairs of twisted-pair wires are surrounded by a flame-retardant halogen-free wire 4 that is concentric with the outer circle of the outer sheath; Root oxygen-free copper 1 twisted. The thickness of the hole-shaped insulating layer 2 is 0.05 mm. In order to achieve the purpose of low dielectric constant to meet the low transmission attenuation of signal transmission and reduce the use of insulating materials and conductors, the measurement shows that when the foaming degree is 26%, the dielectric constant of the insulating material changes from before foaming The 2.1 dropped t...

Abstract

The invention discloses a dual-layer superclass-size digital communication cable and a manufacturing method thereof. The dual-layer superclass-size digital communication cable comprises a cable core and an outer sheath, wherein the cable core comprises four pairs of twisted lines, wherein the four pairs of twisted lines are uniformly arranged in the outer sheath, the cross sections of the outer sheath are in round shapes, the four pairs of twisted lines encircle a flame-retardant halogen free line concentric to the outer sheath, and the twisted-pair cable is formed by twisting two single oxygen-free copper wires sleeved with pore insulation layers. In the superclass-size digital communication cable, new materials of the pore insulation layers are used outside the twisted-pair cable, so that the dielectric constant of the cable core becomes small, the material dosage is reduced, the production cost is reduced, and meanwhile, the signal transmission attenuation during high-frequency transmission is small.

Description

Technical field [0001] The invention relates to a Category 6 digital communication cable and a manufacturing method thereof. Background technique [0002] Since the mid-1980s, with the rapid development of data communication and information technology, the rapid development of network technology and the continuous improvement of computer performance, people’s requirements for the performance of integrated wiring systems have become higher and higher. The current network transmission rate has changed from The previous increase from 10Mb to 100Mb, and with gigabit LAN technology, the network speed is increasing day by day, which means an increase in operating frequency. The higher the operating frequency, the greater the signal transmission attenuation. The traditional Super Category 6 digital communication cable adopts solid-core polyethylene insulation technology structure, and its cable core has large transmission attenuation at high frequencies. In addition, as the cost of raw...
