Abstract

The invention discloses a rail traffic cable. The rail traffic cable comprises an outer protection sleeve; an inner protection sleeve is arranged in the middle position of an inner cavity of the outerprotection sleeve; an isolation layer is arranged between the outer protection sleeve and the inner protection sleeve; insulating core wires are arranged in the inner protection sleeve; each insulating core wire comprises an insulating layer and conductors; the conductors are positioned in an inner cavity of the corresponding insulating layer; a filling layer is arranged between each insulating layer and the corresponding conductors; a blocking layer is arranged between each insulating layer and the inner protection sleeve; fixed rods are fixedly connected with the two sides of the isolationlayer respectively; an inner cavity of each fixed rod is sleeved with a lengthened rod; the surface of each lengthened rod is sleeved with a spring; and the two sides of the spring are fixedly connected with the fixed rods. By virtue of matching of the outer protection sleeve, the inner protection sleeve, the isolation layer, the insulating core wires, the insulating layers, the conductors, the filling layers, the blocking layers, an oxidization resistant layer, a corrosion resistant layer, a waterproof layer and a wear-resisting layer, the problems of easy damage to the surface, poor waterproof effect and short service life are solved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a cable for rail transit. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of trains and railway technologies, There are more and more types of rail transportation, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. Common rail transportation includes traditional railways (national railways, intercity railways and urban railways) ), subways, light rails and trams, and new types of rail transit include maglev rail systems, monorail systems (straddle rail systems and suspended rail systems) and automated passenger rapid transit systems. In Glossary, urban rail transit is defin...
