A network cable for drag chain system

Abstract

The invention is applicable to the technical filed of a cable, and provides a network cable used for a drag chain system. The cable comprises multiple pairs of mutually-stranded core wires, inner division sheaths, a shielding layer, an inner lining sheath and an outer lining sheath; each pair of the core wires comprises two core wires which are stranded mutually; each core wire comprises a conductor and an insulating layer; the conductor is formed by multiple strands of oxygen-free copper wires in a stranding manner; the periphery of the conductor is coated with the corresponding insulating layer; the periphery of each core wire pair is coated with the corresponding inner division sheath; the peripheries of the multiple inner division sheaths are coated with the inner lining sheath; the periphery of the inner lining sheath is coated with the shielding layer; the periphery of the shielding layer is coated with the outer lining sheath; and the insulating layer comprises the following components based on mass percentages: 34-40% of styrene-butadiene block copolymer hydride, 14-26% of white mineral oil, 0.1-0.2% of antioxidant, 15-30% of polypropylene and 5-20% of calcium carbonate. The service life and signal transmission stability of the cable can be greatly prolonged and reinforced.

Description

technical field [0001] The invention belongs to the technical field of cables, in particular to a network cable used in a drag chain system. Background technique [0002] Network cables are widely used in drag chain systems for network video image transmission and signal control of industrial manufacturing automation equipment, such as intelligent lathes, machine tool processing equipment, logistics transportation systems, robots, industrial robotic arms, port machinery, complete equipment installation projects and cranes occasion etc. [0003] The defects of the network cables currently used in the towline system are: the transmission rate of the network signal is slow and the transmission distance cannot meet the requirements, the anti-interference effect is not good, and the life cycle of the cable is only about 4000 times. During the production process of automation equipment, the cables will fail after being used for about half a year, and even broken cores cannot be u...
