Same number of anchors as steel handles
14. Sub-tube
In the overhead cable project, it is mainly used to protect the optical cable and lead the optical cable.
Plastic tube
The overhead cable installation requires 25 meters per kilometer. The indoor channel cable requires 103 meters for every 100 meters, and when looking at the cable, how far the manual hole is from the pole, which is generally very close.
