Abstract
The invention discloses a multiline railway signal cable comprising an external protection layer, an anti-interference layer, a fixing wrapping layer, and a plurality of sub signal cables. The external protection layer is arranged outside the anti-interference layer. The anti-interference layer is arranged outside the fixing wrapping layer. The plurality of sub signal cables are uniformly distributed on the inner side of the fixing wrapping layer. Each sub signal cable comprises an inner protection layer, an inner shielding layer, an inner wrapping layer, insulating sleeves, and a plurality of conductive cores; the insulating sleeves are respectively arranged outside the conductive cores and are uniformly distributed on the inner side of the inner wrapping layer; and the inner protection layer is arranged outside the inner shielding layer. Through the technical scheme, the shielding effect between the lines of the multiline railway signal cable is good, internal interference and external interference of the cable are prevented, and the signal transmission stability of the lines is improved.
