Abstract
The utility model discloses a railway digital signal cable which is composed of conductors, wallet leather insulating layers, star-shaped four line resistance layers, a belting layer, a heat insulation layer, an aluminium sheath, an inner lining layer, a double steel tape armor layer and an outer sheath. The wallet leather insulating layers are extruded outside the conductors to form line cores. The star-shaped four line resistance layers are extruded outside the line cores. The double steel tape armor layer is extruded outside the inner lining layer. The outer sheath is extruded outside the double steel tape armor layer. The railway digital signal cable provided by the utility model has the characteristics of oil resistance, oxygen resistance, moisture resistance and excellent high voltage interference resistance.
