A lightning protection device for an OPGW (optical fiber composite overhead ground wire) optical cable on an outer wall comprises the OPGW optical cable, a grounding point, an optical cable joint box and a grounding network. The grounding point and the optical cable connector box are arranged on the outer wall; the outer wall is provided with an optical cable steering device, a residual cable rack, a rain shelter and a grounding pipeline; the grounding point is connected with the parallel groove clamp through a first grounding wire; the rain shelter is positioned above the optical cable joint box; the optical cable joint box is provided with a second grounding wire; the second grounding wire penetrates through the grounding pipeline and is connected with the grounding grid; the OPGW optical cable is downwards connected with the parallel groove clamp through the optical cable steering device, after the optical cable is led out from the parallel groove clamp, redundant optical cables are wound and fixed on the redundant cable frame and then downwards connected with the optical cable joint box.
Further, the first grounding wire is an aluminum wire.
Further, the second grounding wire is an aluminum wire.
Furthermore, the size of the grounding grid is 5m multiplied by 5m to 20m multiplied by 20 m.
The utility model has the advantages that:
the utility model discloses a set up the earth connection respectively at optical cable and optical cable splice box, ensured when taking place the thunderbolt, can flow into the ground with the forceful electric power effectively, guaranteed that the optical cable also can steady operation under the condition that receives the thunderbolt.
