Abstract

The utility model discloses an optical power ground wire (OPGW) pull-in optical cable safety grounding fixing assembly, which comprises an over cable rack I and an over cable rack II. The over cable rack I is transversely arranged and the over cable rack II is vertically arranged. The two over cable racks are crossed and fixed to form a cross-shaped over cable coiling unit. At least one connecting mechanism I for being fixed to a truss bar is arranged on the over cable rack II. The fixing assembly also comprises an optical cable splice tray. A connecting mechanism II for being fixed to a truss piece is arranged on the optical cable splice tray. The optical cable splice tray is reliably grounded through a grounding drainage piece. An optical cable led out of the optical cable splice tray is coiled up through the cross-shaped over cable coiling unit. The fixing assembly also comprises a plurality of fixing clamps for fixing an optical cable onto the truss piece. Due to the adoption of the above structure of the utility model, an OPGW can be conveniently introduced into the door-shaped truss of a transformer station to be grounded, so that the damage of the optical cable due to a large current flowing through the OPGW is effectively prevented. Meanwhile, the grounding point can be conveniently disconnected so as not to influence the grounding test of the transformer station.
