Adopt wear -resisting cable of thermoplasticity macromolecular material

The utility model relates to a cable, the more specifically adopt wear -resisting cable of thermoplasticity macromolecular material that says so, the oversheath layer of compriseing the polyether polyurethane material has excellent compliance and lower temperature resistance, and fire -retardant effect can be played in setting up of the fire -retardant parting bead of cable when the conflagration takes place, restrain further stretching of conflagration. The oversheath layer contacts with the armor. The armor contacts with copper woven shield. Copper woven shield contacts with the inner sheath layer. Inorganic filler material, separate oxygen layer, internal shield layer, insulating layer, cable conductor and fire -retardant parting bead all set up including the inside of restrictive coating to inorganic filler material is filled full inner sheath in situ portion and is separated the space between oxygen layer and the fire -retardant parting bead, and fire -retardant parting bead has four, and the equipartiti
