However, with the complexity of the existing cable use environment, a customer adds a plurality of units convenient to construct into the cable processing, so that the processing difficulty of the cable is increased.

In order to facilitate cable opening and improve construction efficiency, a plurality of tearing units are required to be added under the cable sheath. At the same time, the cable also requires the addition of a plurality of reinforcing elements in the sheath in order to increase the tensile strength. Moreover, these tearing units and reinforcing units have strict positioning requirements in the finished product, requiring no coincidence of any length of the cable and maintaining a stable angle. Specifically, the aramid fiber reinforcement is wrapped on the cable core in a spiral rotation mode, the tearing unit stably rotates outside the spiral aramid fiber reinforcement in a horizontal direction, then a sheath layer is added, the FRP reinforcement unit is embedded in the sheath in a space vertical state with the tearing unit, and the tearing unit is positioned under the sheath because the product reinforcement unit is embedded in the sheath, namely the reinforcement unit and the tearing unit are not positioned on the same space surface. Particularly, the tearing unit under the sheath is easily changed in position due to the influence of factors such as extrusion pressure fluctuation, pay-off end tension fluctuation, pay-off jumping, cable core friction and the like. The difficulty of this requirement to be achieved on thin cables of 6mm and below is that of straight line rise.
