Abstract

The invention discloses a metal sheath bureau communication cable for rail transit. The metal sheath bureau communication cable comprises a plurality of intertwisted insulated cores which are packed by a wrapping polyester tape. Factice is filled between the intertwisted insulated cores and the wrapping polyester tape. A water blocking layer clads the wrapping polyester tape. A PE heat insulating layer clads the water blocking layer. An aluminum sheath clads the PE heat insulating layer. A low-smoke halogen-free inner sheath clads the aluminum sheath. A high-magnet-conductivity steel tape armoring layer clads the low-smoke halogen-free inner sheath. A low-smoke halogen-free outer sheath clads the high-magnet-conductivity steel tape armoring layer. The metal sheath bureau communication cable greatly improves water blocking performance, shielding performance (information transmission safety), mechanical performance and flame retardance of the cable. The shielding coefficient of a pure aluminum metal sheath and the high-magnet-conductivity steel tape armoring layer to the cable is smaller than or equal with 0.2, thereby greatly improving shielding coefficient of the cable and improving information transmission safety of the cable.
