The reinforcement components (1), the optical fibers (2) and the tearing ports (3) are not contacted with each other. The optical cable of the invention has the advantages that distortion-resistance performance is good; optical cable performance is stable; a service life is long; construction and laying are easy.

The invention discloses a movable anti-aging cable for a stacker-reclaimer. The movable anti-aging cable comprises a fixation tough pipe, a tin cladding layer, a flame-retardant layer, a tensile layerand an oxygen barrier layer. The fixation tough pipe comprises a hollow pipe and a rubber pressing block. The fixation tough pipe is arranged in the tin cladding layer and fixedly connected with theouter surfaces of conductor bodies in a clamped mode; a cavity channel is formed in the middle of a hollow pipe; and the outer surface of the hollow pipe is fixedly connected with the rubber pressingblock perpendicularly. The fixation tough pipe and the conductor bodies form an integrated structure with deformation resistance, so that the overall pressure resistance is enhanced; and the separatedintegrated fixation mode can reduce the material torsion and stretching conditions caused by different deformation amounts due to the internal and external deformation offset of each layer of the cable caused by working movement. Besides, through the control of the tin cladding layer on the internal temperature, the strong flame-retardant property of the flame-retardant layer, the good torsion resistance of the tensile layer, and the thermal aging resistance of the oxygen barrier layer, the aging resistance of the whole cable is improved.
