[0035] The specific technical scheme of the present invention will be explained in conjunction with the drawings.
[0036] Such as figure 1 As shown, an anti-mold, mouse-proof and ant-proof cable for water-blocking electrified railways has a structure from the inside to the outside: conductor 1, conductor water blocking layer 2, conductor shielding layer 3, insulating layer 4, and insulating non-metallic shielding Layer 5, insulating metal shielding layer 6, first water blocking layer 7, inner sheath layer 8, flame retardant wrapping layer 9, armor layer 10, second water blocking layer 11, and outer sheath 12.
[0037] The conductor 1 is a stranded conductor in which a number of copper wires are regularly arranged and twisted together at a specified pitch and adjacent layers are twisted in opposite directions; bare copper composite wires with a single diameter of 2.86 mm and 37 wires are selected, concentrically adjacent The outer diameter of the layers is 28.6±0.05mm after pressi...
