Photoelectric composite medium-voltage reel cable with rated voltage of 3.6/6kV-12/20kV

The utility model discloses a photoelectric composite medium-voltage reel cable with the rated voltage of 3.6/6kV-12/20kV. An optical unit sheath made from a chlorinated polyethylene rubber material capable of being quickly sulphuretted is adopted, so that the optical fiber performance is ensured in the rubber extruding process, and accordingly, all properties of the photoelectric composite medium-voltage reel cable are improved and the service life is prolonged. Besides, owing to a reasonably-designed cable structure and a reasonably-formulated processing technology, for example, the stranding direction, the layer-stranding direction and the lay ratio of conductor braided wires, as well as the cabling layer ratio control, one frame is changed into an active wire releasing design by cabling equipment, and the design of a weaving reinforced layer and the sulfidization degree of both an inner sheath and an outer sheath are controlled, so that the bendability, the tensile performance and the twisting resistance of the cable are ensured and the service life of the cable is prolonged. In addition, owing to a special neoprene sheath material, the cable is endowed with such favorable properties as ultraviolet resistance, oil resistance, low-temperature resistance, abrasion resistance and the like, thereby having improved service performance and prolonged service life.
