Abstract

The invention relates to an industrial network cable, in particular to a special communication double-layer shielding cable for the industrial network. The special communication double-layer shielding cable comprises an outer sheath, in which an insulating core quad is arranged; the insulating core quad consists of a red insulating core wire, a black insulating core wire, a yellow insulating core wire and a blue insulating core wire; the red insulating core wire is stranded with the black insulating core wire to form a red-black core quad; the yellow insulating core wire is stranded with the blue insulating core wire to form a yellow-blue core quad; the red-black core quad is stranded with the yellow-blue core quad; and a shielding layer is arranged between the inner side of the outer sheath and the insulating core quad. The special communication double-layer shielding cable is characterized by high transmission performance and strong external interference resisting capability, which meets the high requirement on the cable signal transmission in the industrial network, and ensures that the signal can be transmitted successfully even if the inner interference of the cable per se is reduced to the lowest value; and meanwhile, the special communication double-layer shielding cable removes the shielding of the external interference signal so that the signal transmission does not distort.

Description

technical field [0001] The invention relates to an industrial network cable, in particular to a double-layer shielded cable dedicated for industrial network communication. Background technique [0002] At present, the requirements for signal transmission of industrial network cables are getting higher and higher, and the existing cables can no longer fully meet the high requirements. The main reason is that the internal interference of the cable itself will also affect the smooth transmission of the signal. At the same time, the existing industrial network cable is not very effective in shielding external interference signals, which eventually leads to distortion in signal transmission. [0003] Based on the shortcomings of the above-mentioned existing industrial network cables, the inventor has developed a "communication double-layer shielded cable dedicated for industrial network" of the present invention. Contents of the invention [0004] The technical problem to be s...
