Description

                             Preformed tension clamp for OPGW

Usage

The product is used to connect OPGW cable and tower in the optic fiber cable erection, the ground wire can protect the OPGW cable and improve the anti-vibration. The special design of the ground wire can guarantee that the preformed tension clamp will not lead to the stress concentration, which does damage to the OPGW cable, so that, ensure the normal life of the cable system.

Structure &material

Shackle     Galvanized steel shackle, used to connect the tower fasteners.

Exstrain rod  Hot dip galvanized steel precision exstrain rod, used to connect thimble and shackle, it can also let the exit cable of the preformed tension  clamp keep at a distance with the tower, as a result, it will guarantee the cable’s Bending radius.

     Thimble  Hot dip galvanized steel precision thimble, in the U-shape bending head, which can make tension clamp connect with exstrain rod.

preformed armor rods  made by galvanized steel wire or galvanized steel wire, there is one Particles emery on the inner wall of the preformed armor rods, this can improve the friction force. The preformed armor is prefabricated into four muon beams when in manufacturing so that it can install correctly and quickly. The corner of the preformed armor is over the outside so that it can avoid extruding the cable.

Preformed armor rods  made into beams by galvanized steel wire or galvanized steel wire, there is strong emery on the inner wall for reducing the lateral pressure on the cable, and meanwhile, it can raise the Grip strength of the preformed tension clamp.

Instruction

1. Used to connect with the terminal tower, strain tower and the connecting tower.

    Specific configuration: terminal tower**-one suite/tower; strain tower**-two suite/tower; connecting tower**-two suite/tower.

2. Select the tension clamp according to the cable diameter and the cable’s rated pulling strength, the users can choose the suitable preformed tension clamp according to the specification table.

3. The ground wire clamp and the tension clamp should be ordered together. It is not allowed to install the ground wire clamp directly on the inner or outer layer performed armor rods of the tension clamp.
