Abstract

The invention discloses a high-speed railway network data cable comprising a main conductor and control conductors. The main conductor and the control conductors are respectively subjected to extrusion molding to form in a double-layer expanded-plastic insulating layer, and are sequentially coated with a non-hygroscopic internal isolation layer, an aluminum-plastic composite belt interlocking armor layer, a tinned-copper-wire braid shielding layer, a non-hygroscopic external isolation layer, a glass fiber braid layer, a water stopping yarn filling layer and a low-smoke-zero-halogen thin-wall outer sheath after being bunched. A low-smoke-zero-halogen inflame-retardant material filing core is arranged on the inner side of the non-hygroscopic internal isolation layer. The high-speed railway network data cable has the advantages that standard stranded structures are combined with bunched or stranded structures, composite shielding formed by aluminum-tape lapping is added to the shielding layer, shielding effect of the cable is improved, the tinned-copper-wire braid shielding layer is optimized, braiding density is larger than 90%, the cable has excellent electromagnetic interference resistance performance, low smoke, zero halogen and flame retardance are realized, and physical and mechanical property is excellent.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-speed railway network data cable. Background technique [0002] Cables suitable for high-speed EMU projects and widely used in the subway and urban rail vehicle market need to have the characteristics of fire resistance, low smoke, halogen-free flame retardant, waterproof, tensile and torsion resistance, and the existing cables are not very good It satisfies the usage requirements, and has complex structure, heavy weight and high cost, and needs to be improved. Contents of the invention [0003] The object of the present invention is to provide a high-speed railway network data cable in order to remedy the defects of the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A high-speed railway network data cable includes a main conductor and a control conductor, the main conductor and the control conductor are res...
