Abstract

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.

Description

technical field [0001] The invention relates to the field of optical cable downcomer processing, in particular to an optical cable downcomer system. Background technique [0002] figure 1 It is a structural diagram of an optical cable downcomer system according to the prior art, such as figure 1 As shown, it includes: substation portal frame 11, lead wire fixing clip 12, ADSS optical cable 13, sealing part 14 (ie, fireproof, waterproof and mud blocking), optical cable downpipe 15, fixing steel belt 16, cable trench 17 and communication room 18 ,From figure 1 It can be seen from the figure that the outlet of the traditional optical cable downcomer faces upwards. In order to prevent rainwater from entering the downcomer, engineers and technicians often use fireproof and waterproof plugging mud to fill and seal the outlet of the cable downcomer. However, the above sealing method is based on experience. Accumulation, there is no scientific basis, and the effective sealing tim...
