Wedge Dead End for OPGW

AFL’s optical ground wire (OPGW) wedge dead end improves the ease and speed of installing OPGW as compared to bolted and formed wire devices. The wedge dead end is sold mostly assembled and only requires connecting three components (the body, top wedge and locking pin) during preparation. The unique cam action in the pivoting cable guide ensures proper alignment of the wedges prior to loading and the wedges automatically provide the necessary gripping action to meet the holding strength requirements. A removal tool (sold separately) is available to unlock the wedges for situations requiring additional adjustment of the dead end.

HIBUS® Series OPQW Suspension

The Hinged Bushing Suspension (HIBUS) is designed to reduce the static and dynamic stress at the attachment point on all types of OPGW fiber cables without the use of protective rods. Eliminating the need for the rods was achieved by the use of a unique bushing system that allows the OPGW cable to better withstand the effects of aeolian vibration. Test results have proven its ability to provide superior protection for your fiber system. The hinged concept on the suspension configuration provides self-alignment of the housing halves. All of the hardware is captive except for the attachment pin.

Test reports available include vibration test, slip test, ultimate strength and angle test. Clamp is rated slip load at 20% of RBS for cables with less than 25,000 lbs breaking load. Contact AFL for slip rating on cables greater than 25,000 lbs RBS.

OPGW Vibration Damper

Vibration dampers work to cancel damaging fatigue caused by wind-induced vibration. Most tuned damping devices operate best near their natural frequencies.

AFL vibrationdampers are designed for efficient transfer and dissipation of energy over a wide spectrum of frequencies. They feature all aluminum clamp construction to match expansion/contraction of conductor and break-away bolts for easy installation and proper torque.
