FIBERLIGN® Formed Wire Dead-End
The FIBERLIGN Formed Wire Dead-End uses two helically shaped formed wire components: an inner layer of structural reinforcing rods (SRR) and an outer-layer dead-end component to distribute axial and compressive loads over the applied area of the OPGW. The distribution of these loads reduces stresses on the central core and optical fi bers of the OPGW.
-
Standard Formed Wire Dead-Ends include right-hand lay SRR and a left-hand lay dead-end component
-
A current transfer tab is included to provide a direct electrical bond between the OPGW and ground lead
-
Current transfer tab is captured between the OPGW and the SRR. No additional fasteners are needed
-
Current transfer tab has a hole diameter that accommodates a standard 1/2"-13 UNC bolt for compatible ground terminal attachments
-
Thimble clevis is provided with each standard assembly to ensure proper long-term performance and support
-
An optional ground wire assembly can be included with the formed wire dead-end
-
SRR and dead-end components can only be reused once for retensioning after initial installation. Hardware components of the dead-end can be reused if they are in good condition.
-
Dead-end components are made of corrosion-resistant materials
-
The FIBERLIGN Formed Wire Dead-End has been thoroughly tested for vibration, mechanical loading, and optical attenuation in accordance with IEEE Standard 1138 and IEEE Standard 1591.1
