Longitudinal and radial water-blocking cable and manufacturing method thereof

The invention discloses a longitudinal and radial water-blocking cable and a manufacturing method thereof. The cable comprises a composite cable core, a wrapping tape layer, a longitudinal wrapping plastic-aluminum composite tape water-blocking layer, an inner sheath, a water-blocking tape layer, an armor layer and an outer sheath which are sequentially arranged from inside to outside. Wherein gaps of the composite cable core are filled with super-absorbent composite water-blocking yarns; the water-blocking tape layer is formed by weaving super-absorbent composite water-blocking yarns; the superabsorbent composite water-blocking yarn is made of base yarn and superabsorbent resin, and the superabsorbent resin is formed by solidifying a superabsorbent resin mixed glue solution on the base yarn. According to the invention, the gaps of the composite cable core are filled with the water-blocking yarns, and the cable core is provided with the longitudinally-wrapped aluminum-plastic composite tape water-blocking lay
