Polyethylene fiber armored umbilical cable

The utility model discloses a polyethylene fiber armored umbilical cable comprising a central liner tube, a cable core sheath, and an outer sheath. Five stainless steel tubes, three cables, and an optical cable are disposed between the central liner tube and the cable core sheath. An inner armoring layer and an outer armoring layer are disposed between the cable core sheath and the outer sheath. The inner armoring layer is a polyethylene fiber armoring layer, and the outer armoring layer is a steel wire armoring layer. The polyethylene fiber armored umbilical cable is advantageous in that the polyethylene fiber armoring layer can be used to replace one steel wire armoring layer, therefore the dead weight of the cable can be reduced, and the tensile strength of the umbilical cable can be improved at the same time.
