The invention relates to an A-class fire-retardant water-proof rat-proof
ant-proof intermediate-
voltage special cable for the
rail traffic. The cable comprises a conductor; a conductor shielding layer, an
insulation layer, an insulation shielding layer, a wrapping layer, a
metal shielding layer, a water
blocking layer, a
flame-retardant layer, an inner sheath, a
metal armored layer, and an outer sheath are arranged successively outside the conductor, wherein the conductor shielding layer, the
insulation layer, and the insulation shielding layer re in a three-layer co-extruded manner. The innersheath is an extruded
halogen-free low-
smoke flame-retardant
oxygen barrier layer formed by wrapping of two alkali-free glass tapes. The outer sheath is formed by extruding an optical
cement by a low-
smoke halogen-free fire-retardant rat-proof
ant-proof high-
polymer material; and the optical
cement has the thickness of 10 to 20 microns. The outer sheath is a
polyvinyl chloride outer sheath; and awhite-
ant-proof
plant additive that is non-toxic and is harmless to the
human body and the environment is added into the outer sheath. The cable has characteristics of excellent
environmental protection effect and good low-
smoke,
halogen-free,
flame-retardant, waterproof, anti-
ultraviolet radiation, rat-proof, and ant-proof performances and the like.
