Anchor clamps for figure-8 cables
Tension clamps designed to anchor figure-8 fiber optic cable of different diameters, and messengers’ types. All the clamps are self-adjusting. Needed mechanical strength and clamp of cable achieved by wedges and conical body of clamp.
All of Jera’s overhead fiber optic tension clamps for type 8 cable divided to 2 groups, depend on the messenger type
* Anchoring clamps for figure-8 cables with steel messenger
* Anchoring clamps for figure-8 cables with dielectric messenger
Each messenger type require specified wedges type and body material. Commonly for FRP, Kevlar messenger we use plastic wedges and body of clamp, whereas for metal messenger we use Zink teeth and aluminum body material. Generally, optical cable with steel messenger require higher mechanical load, and this completely assured by high strength aluminum materials that applied in anchor clamps. The flexible stainless steel bail is typical.
Our wedge tension clamps does not cut the cable jackets and guarantee the long period of usage.
Those fiber optic cable fittings can be applied on dead-end, double dead-ending or double anchoring cable routes.
ADSS anchor clamps are made of
* Flexible stainless steel bail
* Fibre glass reinforced, UV resistant plastic body and wedges
The stainless steel bail allows installations of clamps on pole brackets, hooks.
All the assemblies passed the tensile tests, operation experience with temperatures ranging from –60 °C up to +60 °C test, temperature cycling test, aging test, corrosion resistance test etc.
