Lightening-proof photoelectric composite cable for communication base station

2014 
The utility model relates to the field of the cable technology, especially to a lightening-proof photoelectric composite cable for a communication base station. The lightening-proof photoelectric composite cable consists of a cable core, an inner sheath, an armored layer, an outer sheath, a ground layer, a connecting rib, hanging wires, a hanging wire protective layer, and an optical unit. The outside of the cable core is coated with a first protection layer that is extruded and coated with the inner sheath; the outside of the inner sheath is coated with the a second protection layer; the ground layer is arranged outside the second protection layer; the armored layer coats the outside of the ground layer; the outside of the armored layer is extruded and coated with the outer sheath; the hanging wire protective layer coats the outside of the hanging wires; and one end of the connecting rib is connected with the hanging wire protective layer and the other end is connected with the outer sheath. The cable is characterized in that the hanging wires are arranged outside the optical unit; the optical unit and the hanging wires are arranged in the hanging wire protective layer; and the hanging wires are formed by a plurality of reinforced elements and peripheries of all reinforced elements are at the same cylindrical surface. The provided cable has the following beneficial effects: the manufacturing is simple; the production speed is fast, the ground layer resistivity is low; the maintenance cost is low; and the optical communication is not influenced by lightning stroke.
