Abstract

The invention provides a production process of a network cable. The process comprises the steps of: coating the surface of a copper wire with an insulation material to manufacture single wires havingsurfaces coated with the insulation layers, performing pair twist for each two adjacent single wires after cooling, forming 4 pairs of twisted pairs by twisting 8 single wires for independent cabling,and finally, coating the 4 pairs of cabled twisted pairs and the filling materials into a sheath to obtain a network cable with high temperature resistance and strong deformation resistance. According to the invention, the four twisted pairs are independently cabled without a cross isolation framework, so that the diameter of the network cable can be effectively controlled not to be too thick, the four twisted pairs are kept at relative positions, the balance characteristic and crosstalk attenuation of the network cable are ensured, the balance structure of the network cable is ensured not tobe damaged in the installation process, and the manufacturing cost of the network cable is reduced.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to a production process of network cables. Background technique [0002] A network cable is essential for connecting to a LAN. Common network cables include twisted pair, coaxial cable, and optical cable. Optical cable is currently the most advanced network cable. It is composed of many glass fibers as thin as hair, that is, optical fibers plus insulating sleeves. It is transmitted by light waves. It is characterized by excellent anti-electromagnetic interference, strong confidentiality, fast speed, and large transmission capacity. . However, optical cables have high requirements for port cleaning. Ordinary dust and fingerprints will cause greater attenuation of optical fiber transmission, and even communication interruption. Coaxial cable is a cable with a central copper conductor wrapped by layers of insulated wires. It is characterized by good anti-interferenc...
