Tension assembly
Preformed tension assembly especially designed for OPGW cables. Includes
grounding clamps for tower connection. When the distance between two anchor towers is greater then
the maximum length of OPGW cable drums, there are special tension assemblies for installation in
suspension towers, allowing a cable joint to be included.

Dampers
The dampers are used to absorb the cable vibrations. The number of dampers is
determined by the environmental conditions, the distance between towers, the type of OPGW cable and
the installation parameters. On request, Prysmian can calculate a customized vibration
study.
