Abstract

The invention discloses a moisture-proof railway signal cable, which relates to the field of manufacturing of cables. The signal cable comprises four groups insulating conductors, wherein a water-blocking tape taped covering, an aluminum-plastic compound belt dampness prevention layer, a polyethylene adhesive protective layer, a longitudinal corrugated steel belt armor layer and a polyethylene outer restrictive coating are arranged in sequence outside the insulating conductors; and a petroleum butter packing layer is arranged among the insulating conductors in the water-blocking tape taped covering. By adopting the water-blocking tape taped covering, the aluminum-plastic compound belt dampness prevention layer and the petroleum butter packing layer in the cable, the cable has a good moisture prevention function.

Description

technical field [0001] The invention relates to the technical field of cable manufacture, in particular to a moisture-proof railway signal cable. Background technique [0002] With the extension of the railway and the upgrading of technology, the performance requirements of the supporting cables are higher, especially in some rainy and humid areas, the moisture-proof and interference-proof of the cables is particularly important. Contents of the invention [0003] In order to solve the defect that the existing cables are not suitable for use in rainy and humid areas, the invention provides a moisture-proof railway signal cable. [0004] The present invention includes four sets of insulated conductors, on which a water-blocking tape wrapping layer, an aluminum-plastic composite tape moisture barrier, a polyethylene bonding sheath, a longitudinally wrapped corrugated steel tape armoring layer, and a polyethylene outer layer are sequentially arranged on the outside of the ins...
