The lead-down clamp is used to lead down the optical cable and fix the optical cable when it is jumpered, which improves the mechanical performance of the clamp. It is mainly used for the communication line of the newly built overhead high-voltage power transmission system of 35kv and above. The stainless steel tube and cable core stranding design is reasonable, and the optical fiber is redundant. The length is accurate; the all-dielectric self-supporting optical cable (adss) is suspended on the pole tower with the line turning angle less than 25°
Down-lead clamps for rubber towers are used to fix the up and down or up of the optical cable on the tower so that it will not shake and avoid the optical cable from wearing.
Features:
1.Wide range of application: It is suitable for skeleton type, layer stranded type, beam tube type armored and non-armored fiber optic cables, and is flexible in use.
2. Dielectric strength: 15kv DC, no breakdown in 2 minutes.
3.Function of the down-lead clamp for the stainless steel belt-shaped pole: fasten the optical cable that is drawn down or up from the pole to the pole so that it cannot be shaken, so as to avoid the abrasion of the optical cable.
4.Conditions: the first and end poles, connecting poles, etc. of the optical cable line.
5.Usage: Generally install one every 1.5 meters.
