CAT6A-type network cable traveling cable used for elevator

Abstract

The invention discloses a CAT6A-type network cable traveling cable used for an elevator. The CAT6A-type network cable traveling cable comprises a plurality of line pair structures, sheathing intervals, two fully withdrawn twisted steel wire ropes and an environmentally-friendly low-smoke halogen-free elastomer outer sheath, wherein the line pair structures are parallel structures arranged in one line, and every three or four line pair structures form a group; the sheathing intervals are arranged between every two groups of line pair structures; the two fully withdrawn twisted steel wire ropesare arranged on the outer sides of the line pair structures; and the environmentally-friendly low-smoke halogen-free elastomer outer sheath is used for extruding the line pair structures and the fullywithdrawn twisted steel wire ropes. Each line pair structure comprises two line pair cores twisted through narrow-spacing comparison, a compound shielding layer and an outer insulating layer. The compound shielding layer comprises a polyester belt, an aluminum foil shielding layer and a tinned copper braid shielding layer. The CAT6A-type network cable traveling cable has the advantages of reliable electric performance and stable transmission characteristic, the whole flat cable is balanced in structure and uniform in symmetric stress, the service life of the cable is prolonged, the safety ofthe cable is improved, the life requirement of three million times for the traveling cable can be met, and the cost of the cable is reduced effectively.

Description

technical field [0001] The invention relates to a data cable, more specifically, to a CAT6A type network cable accompanying cable for an elevator. Background technique [0002] At present, coaxial cables, shielded wire pairs, network cables, and optical fiber cables are generally used in elevator systems to transmit signals such as media, video, and broadcasting. Coaxial cables and shielded wire pairs are gradually eliminated because they use analog signals. Network cables are more and more favored by customers because of their low cost and cheap price compared with optical fibers. At present, the signal frequency used in the elevator system is low, generally below 10MHz, and the performance requirements for the network cable are not high. Generally, the CAT6 network cable can meet the basic communication requirements by improving the conductor and cable pair. [0003] However, in order to solve the current problem of weak mobile communication signals in high-rise residenti...
