Communication cable for information transmission

Abstract

The invention discloses a communication cable for information transmission. The communication cable is sequentially provided with an outer sheath layer, a nylon sheath layer and an insulation layer from the outside in. A reinforced cable core is arranged under the insulation layer; conductive cores are stranded around the reinforced cable core and wrapped by the insulation layer; two metal detection wires are arranged symmetrically between the insulation layer and the nylon sheath layer; and the reinforced cable core is provided with a plurality of reinforcing ribs, which protrude along the radial direction and are mutually independent, at intervals. The metal detection wires are used for detecting whether the communication cable is stolen or cut off in real time, accurately determining the fault occurring places and giving a feedback in time; the interval arrangement allows the inner core to deal with the tension more effectively when the communication cable is pulled in the length direction; and the mutually-independent reinforcing ribs do not hinder the arrangement of the cables in the insulation layer.

Description

Technical field [0001] The invention belongs to the field of communication technology, and particularly relates to a communication cable for information transmission. Background technique [0002] Wire cables are cables that transmit telephones, telegraphs, fax documents, television and radio programs, data and other electrical signals. It is formed by twisting more than one pair of mutually insulated wires. Compared with overhead open wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less affected by natural conditions and external interference. [0003] Chinese patent document CN203205141U discloses a communication cable that includes a cable core and an outer sheath located outside the cable core. At least one plastic optical fiber is also provided in the outer sheath. When the light source is applied to the plastic optical fiber at the collecting end or the using end, the plastic optical fib...
