The lead-down clamp is used to lead down the optical cable and be fixed 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°.
Features
1.It is suitable for skeleton type, layer stranded type, beam tube type armored and is flexible in use.
2. Dielectric strength: 15kv DC, no breakdown in 2 minutes.
3.fasten the optical cable that is drawn down or up from the pole to the pole so that it cannot be shaken
4.Conditions: the first and end poles, connecting poles, etc. of the optical cable line.
5.Usage: Generally install one every 1.5 meters.
Application
1. For fiber optic cable connecting tower, tower cable lead terminal and the middle under the arched part of the tension cable tower fixed, each 1.5 meters with a set of general, other needs can also use a fixed place.
2. The down lead clamp is used in the immobility of OPGW/ADSS on pole/tower. It is suitable for the riveting of fiber when jumping or down lead. And it was commonly installed every 1.5 to 2 meter each set. This clamp bears the excellence of easy installation, adjustable range be suitable for different Dia.
