Abstract

The invention provides a magic tape bushing internal shielding railway digital signal cable comprising a cable core and a protective layer which wraps outside the cable core. The cable core comprises at least one shielding four-wire set. The shielding four-wire set is formed by four single insulating wires of different colors through twisting, and the external part of the single insulating wires is provided with a high-flame-retardant heat-shrinkable bushing and a magic tape bushing shielding layer in turn in a wrapping way. The protective layer outside the cable core comprises a cable core wrapping tape layer, a metal shielding layer, a polyethylene adhesive protective layer, a double steel tape armored layer and an external sheath which are arranged from inside to outside in turn. The cable is simple in production technology, high in protection efficiency, stable in quality and convenient to use. The magic tape bushing shielding layer is adopted so that the cable has excellent heat conducting performance, great shielding effect, great corrosion resistance, aging resistance and wearing resistance and higher anti-fatigue performance. The shielding four-wire set is wrapped by the high-flame-retardant heat-shrinkable bushing, and core wire insulation is not damaged in the production process so that the flame retardation performance of the cable can be enhanced.
