Design points of light all-media self-supporting optical cable lines(5)

- Nov 16, 2018 -

Because the allowable tension of the light all-media self-supporting optical cable is small, the sag should be left during installation; the sag is the ratio of the sag to the gear, as shown in Figure 2. The greater the sag, the smaller the tension of the cable, but because the light self-supporting cable is laid under the power line and the sag is large, the distance between the cable and the ground may be insufficient. Generally, the sag of the winter cable is required. 1.0% and 1.5% in summer.

The light full-media self-supporting optical cable is usually not more than 50 meters, and the maximum is no more than 100 meters; the maximum distance across the road is no more than 70 meters. Where the gear distance exceeds the required paragraph, appropriate reinforcement measures should be used.
