Optical cable lead-down pipe system

The invention discloses an optical cable lead-down pipe system. The optical cable lead-down pipe system includes a transformer station door type framework and an optical cable lead-down pipe, whereinthe optical cable lead-down pipe is used for leading an optical cable out from an optical cable trench, and includes a ground part of the lead-down pipe and an underground part of the lead-down pipe;the top end of the ground part of the lead-down pipe includes a bended segment 1; the underground part of the lead-down pipe is laid to the optical cable trench; the transformer station door type framework is used for fixing the ground part of the lead-down pipe; and the bottom end of the transformer station door type framework is arranged at an underground preset distance location. The optical cable lead-down pipe system solves the technical problem that in the related arts, a blocking mode for the optical cable lead-down pipe is lower in the reliability. 本发明公开了种光缆引下管系统。其中，该光缆引下管系统包括：变电站门型架，光缆引下管，光缆引下管，用于将光缆从光缆沟引出，其中，
